Feedlot Noise Reduction and Sound Management

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Feedlot noise originates from animal vocalizations (bellowing during feeding, sorting, or adjustment), equipment operation (feed mixers, grinders, hydraulic systems), and traffic (trucks, tractors), with peak impact during feeding, processing, and loading/unloading.
• Effective noise management requires a multi-pronged approach: source reduction (consistent feeding schedules, low-stress cattle handling, equipment maintenance), path control (solid sound barriers like wood or concrete panels, earth berms, or enclosed buildings), and receiver protection (worker hearing protection above 85 dB(A) TWA).
• Sound travels via waves, with levels decreasing by approximately 6 dB(A) per doubling of distance, but can be amplified by temperature inversions and wind direction, necessitating site-specific analysis of sound propagation.
• Structural solutions like solid panel fences (8-12 ft tall, continuous, no gaps), earth berms (6-8 ft tall, stable base), and enclosed buildings with sound-absorbing materials are critical for containing noise that cannot be mitigated at the source.
• A proactive noise audit and complaint tracking are essential for identifying loudest sources and times, documenting mitigation efforts, and fostering positive community relations through open communication and prompt, professional responses to concerns.

Feedlot noise is more than an annoyance. It affects cattle behavior, worker safety, and your standing with neighbors. This guide explains where feedlot noise comes from, how it travels, and what you can do to reduce it. It is written for feedlot owners, managers, and operators who are planning new facilities or looking to improve existing ones. You will find practical steps for managing noise at the source, along the path, and at the receiver, plus guidance on monitoring, community relations, and when to bring in outside help.

At a Glance

Understanding Feedlot Noise

Feedlot noise is a complex mix of sounds from animals, equipment, and people. To manage it well, you need to understand what makes noise, how loud it is, and how it travels beyond your property line.

What Causes Feedlot Noise

Cattle are social animals that use vocalization to communicate. In a feedlot setting, you will hear a range of sounds from the animals themselves. Bellowing is most common during feeding times when cattle anticipate feed delivery. It also occurs when cattle are moved through alleys, sorted through the chute, or separated from pen mates. New arrivals often vocalize more during their first days as they adjust to the new environment. Cows calling for calves and bulls establishing dominance add to the mix.

The equipment on a feedlot produces steady and intermittent noise. Feed trucks and tractors moving through the alleys create engine noise. The feed mixer itself produces a constant mechanical hum. Grinding and rolling grain adds higher frequency noise. Diesel engines on older trucks can be particularly loud. Hydraulic systems on loaders and skid steers whine when operating. The banging of metal gates, latches, and sorting panels creates sharp, impulsive sounds that carry far.

Processing facilities generate their own noise. The hydraulic squeeze chute clanks and bangs. The crowd pen gate scrapes against the alley walls. The vaccination gun clicks. The branding iron hisses. These sounds are short but can be intense, especially inside a covered building where sound reflects off metal walls and roofs.

Ventilation fans on enclosed barns produce continuous low frequency noise. This is more of an issue for workers inside the building than for neighbors, but large banks of fans can be heard at a distance. Feed mill operations add grain handling noise from augers, bucket elevators, and the mill itself.

Truck traffic is a major noise source that many operators overlook. Semi trucks arriving to deliver feed ingredients or to load finished cattle create engine braking noise, air brake releases, and the rattle of trailers. These events often happen early in the morning or late at night to avoid heat stress on cattle or to meet packer schedules.

How Loud Is Feedlot Noise

Noise is measured in decibels on the A weighted scale, written as dB(A). This scale approximates how the human ear perceives different frequencies. A quiet rural area sits around 30 to 40 dB(A). Normal conversation is about 60 dB(A). A passing diesel truck at 50 feet is around 80 to 85 dB(A). A banging metal gate can spike above 100 dB(A) at close range.

For workers, the Occupational Safety and Health Administration standard sets the permissible exposure limit at 90 dB(A) over an 8 hour time weighted average. At 95 dB(A), the permitted exposure drops to 4 hours. At 100 dB(A), it drops to 2 hours. At 105 dB(A), only 1 hour is allowed. If you have workers spending full shifts in areas with steady equipment noise, you should measure the sound levels and provide hearing protection where needed.

For neighbors, the concern is different. Rural residential areas typically have ambient noise levels around 40 to 50 dB(A). A feedlot operation that raises nighttime noise levels by 10 dB(A) or more can be noticeable and disruptive. Noise that is intermittent and unpredictable, such as banging gates at odd hours, tends to bother people more than steady noise.

How Sound Travels

Sound travels in waves that spread out from the source. As distance from the source increases, sound levels decrease. In open flat terrain, sound drops by about 6 dB(A) for every doubling of distance. This is called the inverse square law. A sound that measures 90 dB(A) at 10 feet from the source measures about 84 dB(A) at 20 feet, 78 dB(A) at 40 feet, and 72 dB(A) at 80 feet.

Several factors change how sound behaves in the real world. Temperature inversions can cause sound to travel much farther at night. When the air near the ground is cooler than the air above it, sound waves bend downward and carry farther. This is why neighbors may hear feedlot noise more clearly in the early morning hours even when the feedlot is not any louder.

Wind also affects sound travel. Sound travels farther downwind and is reduced upwind. A neighbor who is downwind of the feedlot will hear more noise than one who is upwind. Vegetation can absorb some high frequency sound, but dense tree belts only reduce noise by about 5 to 10 dB(A) over a wide band. This is helpful but not a complete solution.

Topography matters. A hill between the feedlot and a neighbor blocks line of sight and reduces sound. A valley can channel sound toward specific locations. Buildings and solid fences cast acoustic shadows. Understanding how sound travels from your specific site helps you target your noise reduction efforts.

Planning a Noise Management Strategy

A good noise management plan starts before you build or modify a feedlot. If you are planning a new facility, you have the most options available. If you are working with an existing feedlot, you can still make meaningful improvements.

Site Selection and Layout

When choosing a site for a new feedlot, consider the noise impact on surrounding properties. Look at the location of neighboring homes, schools, churches, and businesses. Check local zoning regulations and any noise ordinances that apply to agricultural operations. Some areas have right to farm laws that protect existing operations, but these do not protect you from nuisance claims if you are not following good management practices.

The layout of the feedlot itself affects noise. Place the loudest operations, such as the feed mill, grain processing area, and truck loading facilities, as far from neighbors as practical. Orient the feedlot so that the main traffic flow moves away from neighboring homes rather than toward them. Use natural features such as hills and existing vegetation to your advantage.

Pen arrangement matters too. Cattle that are close to the property line will vocalize more during feeding. If you can place the most active pens away from the boundary, you reduce the noise that reaches neighbors. Consider which pens will hold newly arrived cattle, as these animals tend to be the most vocal during their adjustment period.

Noise Barriers

Sound barriers are one of the most effective structural solutions for feedlot noise reduction. A barrier works by blocking the direct path of sound between the source and the receiver. For a barrier to be effective, it must be solid, continuous, and tall enough to break the line of sight between the noise source and the neighbor.

The barrier should be placed as close to the noise source as practical, or as close to the receiver as practical. The closer the barrier is to either the source or the receiver, the taller it must be to block the sound path. A barrier placed midway between the source and receiver gives the best overall performance for a given height.

Barrier materials vary in effectiveness. A solid wood fence with no gaps works well. Concrete panels are highly effective. Earth berms are effective if they are tall enough and planted with vegetation to prevent erosion. Metal sheeting can work but may reflect sound rather than absorb it. Adding sound absorbing material to the side facing the noise source improves performance.

The height of the barrier is critical. A barrier must be tall enough to block the line of sight from the noise source to the receiver. For a feedlot where the noise source is cattle at ground level and the receiver is a neighbor in a single story home, a barrier of 8 to 12 feet is often needed. If the neighbor has a two story home or spends time on an upper deck, the barrier may need to be taller.

Barriers must be continuous. A gap of even a few feet can allow significant sound to pass through. This is especially true for gaps at the bottom of the barrier. Make sure gates and access points in the barrier are solid and kept closed.

Vegetation and Landscaping

Trees and shrubs can contribute to noise reduction, but they are not a replacement for solid barriers. A dense planting of evergreen trees can reduce noise by 5 to 10 dB(A) over a wide band. The key is density. A single row of trees with open space between them does little. A multi row planting with trees spaced closely and understory shrubs filling the lower levels works much better.

Plant trees that keep their foliage year round for consistent noise reduction. Evergreen species such as spruce, fir, and cedar work well in most climates. The planting should be at least 50 to 100 feet deep to achieve meaningful reduction. The trees should be planted close together, with rows spaced 8 to 12 feet apart and trees spaced 6 to 10 feet within rows.

Vegetation also provides a psychological benefit. A screen of trees between the feedlot and a neighbor reduces the visual impact of the operation. People are often less bothered by noise they cannot see the source of. Even if the noise reduction from vegetation is modest, the visual screening improves neighbor relations.

Managing Noise at the Source

Reducing noise at the source is the most direct approach. This involves changing how you manage cattle, maintain equipment, and schedule activities.

Cattle Handling and Behavior

Cattle vocalize for specific reasons. Understanding those reasons helps you reduce noise. Hunger is the most common trigger. Cattle that are fed on a consistent schedule learn when to expect feed. They vocalize more in the hour before feeding time. If you can shift feeding times to occur when neighbors are less likely to be disturbed, you reduce complaints.

Sudden changes in routine cause cattle to vocalize. If you normally feed at 7 AM and one day you feed at 9 AM, the cattle will bellow more. Keep feeding schedules as consistent as possible. When you must change the schedule, do it gradually over several days.

Moving cattle creates noise. Cattle that are handled calmly and quietly move through alleys with less bellowing. Cattle that are rushed, prodded, or frightened vocalize more. Train your crew in low stress cattle handling techniques. Move cattle at a walk. Use the flight zone and point of balance to guide animals rather than forcing them. Reduce the use of electric prods and hot shots.

Newly arrived cattle are the most vocal. They are stressed from transport and adjusting to a new environment. If possible, place new arrivals in pens away from neighbors. Give them a few days to settle before processing. Provide clean water and feed immediately so they can establish a routine.

Separating cattle from pen mates causes vocalization. When you sort cattle for processing or shipping, the animals left behind will call for those that were removed. This is temporary but can be loud. If you can sort cattle late in the day or at a time when neighbors are less likely to be home, you reduce the impact.

Equipment Maintenance

Well maintained equipment is quieter than equipment that is worn or loose. Gates that drag on the ground or have worn hinges rattle and bang. Latches that do not catch properly slam. Sorting panels with loose bolts clank. Regular maintenance reduces these noise sources.

Check gates and latches monthly. Tighten hinges, replace worn latches, and adjust gates so they swing freely without dragging. Install rubber bumpers on gates that tend to slam. Use nylon or rubber stops on sorting panels to reduce metal to metal contact.

Feed trucks and tractors should have proper exhaust systems. A leaking exhaust manifold or a hole in the muffler can make a truck significantly louder. Check exhaust systems during routine maintenance. Replace worn mufflers promptly.

The feed mixer produces noise from the augers and the material being mixed. Worn bearings and gears increase noise. Keep the mixer properly lubricated and replace worn parts. The type of feed being mixed affects noise. Mixing dry hay produces more noise than mixing silage or wet distillers grains. If you have flexibility in your ration and the noise is a problem, consider how ingredient choices affect sound levels.

Grain processing equipment such as roller mills and hammermills produces continuous noise. These are often located in or near the feed mill. If the mill is close to neighbors, consider enclosing the equipment in a building with sound absorbing material on the interior walls. This contains the noise and reduces what reaches the property line.

Operational Scheduling

The timing of noisy activities has a big impact on neighbor relations. Most neighbors are more tolerant of noise during daytime hours and less tolerant early in the morning, late at night, and on weekends.

Feeding times are the most predictable source of cattle vocalization. If you feed at 5 AM, the cattle will start bellowing around 4 AM. If you can shift feeding to 7 AM or later, you reduce early morning noise. This may not be practical in hot weather when you want to feed early to avoid heat stress. In that case, consider feeding the pens closest to neighbors later in the morning.

Processing days are inherently noisy. The chute, the crowd pen, and the cattle all create sound. Schedule processing for mid morning or early afternoon when neighbors are more likely to be away or less sensitive to noise. Avoid processing on weekend mornings when neighbors may be trying to sleep in.

Truck traffic is a major noise source that you can control. Schedule feed deliveries and cattle loading during daytime hours. If you must load cattle early in the morning to meet packer schedules, consider using a loading facility that is located away from neighbors. Keep truck engines from idling for long periods. Ask drivers to avoid engine braking when approaching the feedlot.

Worker Practices

Workers can reduce noise through their daily practices. Train crew members to close gates quietly rather than letting them slam. Use the latch rather than letting the gate swing and bang. When moving cattle, use voice and body position rather than shouting. Shouting adds to the noise and also stresses the cattle.

Workers should wear hearing protection in areas with high noise levels. Provide ear plugs or ear muffs and require their use in the feed mill, near the mixer, and around processing equipment. Post signs in high noise areas reminding workers to protect their hearing.

Sound Barriers and Structural Solutions

When source reduction is not enough, structural solutions help contain noise. These range from simple fence modifications to complete buildings for noisy equipment.

Fencing and Panels

The standard feedlot fence of metal pipe or cable does little to reduce noise. Sound passes through the open spaces between rails. Replacing perimeter fencing with solid panels creates a sound barrier while still containing cattle.

Solid panels can be made of wood, concrete, or metal. Wood panels are common and effective. Use rough sawn lumber that is at least 1 inch thick. Overlap the boards or use tongue and groove construction to eliminate gaps. A double layer of boards with a layer of building paper between them improves sound reduction.

Concrete panels are durable and require little maintenance. They are available in precast sections that can be installed quickly. The panels should extend from ground level to a height of at least 8 feet for effective noise reduction. Concrete also reflects sound, so adding an absorptive surface on the feedlot side improves performance.

Metal panels are effective if they are solid and well sealed. Corrugated metal panels can be installed vertically with the corrugations running up and down. Seal all joints and gaps. Metal panels tend to reflect sound, so consider adding sound absorbing material on the interior side.

Earth Berms

An earth berm is a mound of soil that acts as a sound barrier. Berms are effective because they are massive and have no gaps. They also provide visual screening and can be planted with grass or trees to improve appearance.

A berm should be at least 6 to 8 feet tall to provide meaningful noise reduction. The taller the berm, the better the performance. The berm should be wide enough at the base to be stable. A typical berm has side slopes of 3 to 1 or flatter.

Build the berm as close to the noise source as practical. The closer the berm is to the source, the shorter it needs to be to block the sound path. A berm placed along the feedlot boundary works if the boundary is close to the noise source. If the boundary is far from the pens, the berm may need to be very tall.

Plant the berm with grass to prevent erosion. Consider planting a row of trees on top of the berm for additional noise reduction and visual screening. The combination of a berm and vegetation is one of the most effective natural noise barriers available.

Enclosures for Noisy Equipment

The feed mill, grain processing area, and other noisy equipment can be enclosed in buildings that contain the sound. A simple pole building with metal siding reduces noise by about 10 to 15 dB(A) when the equipment is inside. Adding insulation to the walls and ceiling improves sound reduction.

Sound absorbing material on the interior walls reduces reflected sound. Fiberglass insulation covered with perforated metal or fabric is commonly used. The material absorbs sound energy rather than reflecting it. This reduces the overall noise level both inside and outside the building.

Ventilation must be maintained when enclosing equipment. Engines and motors generate heat that must be exhausted. Use ventilation openings that are designed to reduce sound transmission. Install sound attenuators or baffles in ventilation openings to allow air flow while blocking sound.

Loading Facilities

Loading cattle is a noisy operation. The cattle are excited, the truck is running, and the loading chute bangs. If your loading facility is close to neighbors, consider relocating it or modifying it to reduce noise.

A loading chute with solid sides reduces the noise that escapes. The cattle are contained within the chute and their vocalization is partially blocked. Adding a roof to the loading chute further contains the sound.

The loading area should have a solid surface that does not amplify sound. Concrete is better than gravel for this purpose. The truck should be positioned so that the engine is pointed away from neighbors when loading. Ask drivers to shut off the engine when the truck is parked during loading.

Common Mistakes in Feedlot Noise Management

Many feedlot operators make the same mistakes when trying to reduce noise. Avoiding these errors saves time and money.

Mistake 1: Ignoring the Problem

The most common mistake is doing nothing. Many operators assume that noise is part of the business and neighbors should accept it. This attitude leads to complaints, regulatory action, and damaged community relations. Addressing noise early is almost always easier and cheaper than responding to a formal complaint.

Mistake 2: Focusing Only on Cattle Noise

Operators often assume that cattle bellowing is the only noise that matters. In reality, equipment noise, truck traffic, and gate banging often bother neighbors more than cattle vocalization. A complete noise audit identifies all sources, not just the most obvious one.

Mistake 3: Building Barriers That Are Too Low

A 4 foot fence does little to reduce noise. Sound travels over the top of a low barrier. For effective reduction, the barrier must break the line of sight between the source and the receiver. This usually requires a height of 8 feet or more.

Mistake 4: Leaving Gaps in Barriers

A barrier with gaps is much less effective than a continuous barrier. Even a small gap allows significant sound to pass through. Gates in barriers are common problem areas. Make sure all gates are solid and kept closed.

Mistake 5: Using Vegetation Alone

Trees and shrubs can help, but they are not a substitute for a solid barrier. A single row of trees provides minimal noise reduction. Even a dense planting only reduces noise by 5 to 10 dB(A). Use vegetation as a supplement to solid barriers, not as the primary solution.

Mistake 6: Forgetting About Workers

Noise management is not just about neighbors. Workers in the feed mill, near the mixer, and around processing equipment are exposed to high noise levels. Failing to provide hearing protection puts workers at risk and may violate workplace safety regulations.

Mistake 7: Inconsistent Scheduling

Making noise reduction efforts only some of the time confuses neighbors and reduces trust. If you commit to avoiding early morning processing, stick to that commitment. Inconsistent efforts make it harder to defend your operation if a complaint is filed.

Mistake 8: Being Defensive With Neighbors

When a neighbor complains about noise, the worst response is to become defensive or dismissive. This escalates the conflict and makes it more likely that the neighbor will pursue formal action. Listen to the complaint, acknowledge the concern, and explain what you are doing to address it.

Monitoring and Recordkeeping

You cannot manage what you do not measure. A noise monitoring program helps you track noise levels, identify problems, and document your efforts.

Conducting a Noise Audit

Start with a basic noise audit of your feedlot. Walk the facility at different times of day and note the loudest sources. Pay attention to feeding times, processing days, and loading operations. Identify which activities produce the most noise and when they occur.

Use a sound level meter to measure noise at key locations. Measure at the source, at the property line, and at the nearest neighbor's property. Take measurements at different times of day and under different weather conditions. Record the date, time, weather, and activity for each measurement.

A basic sound level meter is available for under 100 dollars. More advanced meters with data logging capabilities cost more but provide better documentation. If you need professional grade measurements for a legal dispute, hire an acoustic consultant.

Tracking Complaints

Keep a log of all noise complaints. Record the date, time, the name of the person complaining, the nature of the complaint, and the action you took. This documentation is valuable if a complaint escalates to a legal dispute. It shows that you are taking the issue seriously and making good faith efforts to address it.

Follow up with neighbors who complain. Let them know what you have done to address their concern. Ask if the situation has improved. A personal follow up call or visit goes a long way in maintaining good relations.

Regular Reviews

Review your noise management plan at least once a year. Walk the facility and look for new noise sources. Check barriers for gaps or damage. Verify that gates and latches are still in good condition. Talk to your crew about noise issues and get their input on improvements.

Document your review and any changes you make. This record shows that noise management is an ongoing priority rather than a one time effort.

Community Relations

Feedlot noise is as much a community relations issue as it is a technical issue. How you interact with neighbors affects how they perceive your operation and whether they file complaints.

Open Communication

Introduce yourself to neighbors before they have a reason to complain. Let them know what your operation does and what they can expect. Provide your contact information and encourage them to call you directly with concerns. A neighbor who knows they can talk to you directly is less likely to call authorities.

Send a letter to neighbors before major events that may create noise, such as a large processing day or a construction project. Explain what will happen and how long it will last. This advance notice reduces surprise and gives neighbors a chance to plan around the noise.

Responding to Complaints

When a neighbor complains, respond quickly and professionally. Thank them for bringing the issue to your attention. Ask specific questions about what they heard and when. This helps you identify the source of the noise.

Explain what you are doing to address the problem. Be honest about what you can and cannot change. If you cannot eliminate the noise entirely, explain what you are doing to reduce it and what the neighbor can expect.

Follow up after you have made changes. Ask the neighbor if the situation has improved. If it has not, continue working on solutions. A neighbor who sees genuine effort is much less likely to pursue formal action.

Working With Local Officials

Build relationships with local officials before problems arise. Invite the county commissioner, planning board members, or township supervisor to tour your operation. Explain what you do and how you manage noise. This creates goodwill that is valuable if a complaint is filed.

If a complaint does escalate, cooperate fully with local officials. Provide your noise monitoring data and complaint log. Show what you have done to address the issue. A documented history of good faith efforts is your best defense in a nuisance claim.

When to Call a Professional

Most feedlot noise issues can be addressed with the strategies in this guide. Some situations require professional help.

Acoustic Consultant

Consider hiring an acoustic consultant when you face a formal complaint, a regulatory action, or a lawsuit. A consultant can perform professional noise measurements, model sound propagation, and recommend specific solutions. Their expertise and credibility are valuable in legal proceedings.

An acoustic consultant can also help with planning a new facility or major expansion. They can model the noise impact of different layouts and recommend the best configuration before you invest in construction.

Veterinarian

Call a veterinarian if you notice changes in cattle behavior related to noise. Cattle that are excessively stressed by noise may show reduced feed intake, increased aggression, or signs of illness. A veterinarian can assess the animals and recommend management changes.

A veterinarian can also help if cattle are vocalizing excessively for reasons other than normal behavior. Excessive bellowing can indicate pain, illness, or distress. A health check may identify a problem that is causing the noise.

Extension Agent

Your local agricultural extension agent is a valuable resource for feedlot noise management. Extension agents can provide information on best practices, connect you with other producers who have addressed noise issues, and help you navigate local regulations.

Extension agents can also help with community relations. They may be able to facilitate conversations between you and neighbors or provide educational materials that explain agricultural operations to non farming audiences.

Attorney

If a noise complaint escalates to a formal nuisance claim or regulatory action, consult an attorney who handles agricultural law. An attorney can explain your rights under right to farm laws and help you respond to legal action.

Do not wait until you are served with a lawsuit to contact an attorney. If you receive a formal complaint or notice of violation, seek legal advice promptly. Early intervention often prevents more serious legal problems.

Frequently Asked Questions

How much does a feedlot sound barrier cost?

The cost varies widely based on material, height, and length. A basic wood privacy fence costs 15 to 30 dollars per linear foot installed. Concrete panels cost 50 to 100 dollars per linear foot. An earth berm costs 5 to 15 dollars per cubic yard of fill, plus the cost of the land it occupies. For a typical feedlot, a perimeter sound barrier can cost anywhere from 10,000 to 100,000 dollars or more depending on the size of the area to be enclosed.

Will trees block feedlot noise?

Trees help but are not a complete solution. A dense planting of evergreen trees can reduce noise by 5 to 10 dB(A) over a wide band. This is meaningful but not enough to solve a serious noise problem. For best results, combine trees with a solid barrier such as a fence or earth berm. Trees also provide visual screening, which improves neighbor relations even when the noise reduction is modest.

What is the quietest time to feed cattle?

Feeding cattle later in the morning is quieter for neighbors. Cattle begin vocalizing in anticipation of feed about an hour before feeding time. If you feed at 7 AM, the cattle start bellowing around 6 AM. Shifting feeding to 8 AM or later reduces early morning noise. In hot weather, you may need to feed early to avoid heat stress. In that case, feed the pens closest to neighbors later in the morning.

How far away should a feedlot be from a house?

There is no single distance that guarantees no noise complaints. Sound from a feedlot can travel a mile or more under certain conditions, especially at night during temperature inversions. A distance of at least half a mile reduces noise to near ambient levels in most conditions. Local zoning regulations may specify minimum distances. Check with your local planning department for requirements in your area.

Do cattle get used to noise?

Cattle habituate to constant, predictable noise. They become accustomed to the steady hum of equipment and the regular sounds of feeding. However, cattle startle at sudden, loud, or novel sounds. This is why banging gates and sudden equipment noises stress cattle more than continuous noise. Consistent routines and well maintained equipment reduce startle responses.

What noise level is dangerous for cattle?

Research on cattle and noise is limited, but cattle have sensitive hearing similar to humans. Prolonged exposure to noise above 85 dB(A) can cause stress and reduced feed intake. Sudden loud noises above 110 dB(A) can cause a startle response that leads to injury. If your feedlot has areas with sustained noise above 85 dB(A), consider moving cattle away from those areas or reducing the noise at the source.

Can I be sued for feedlot noise?

Yes, neighbors can file a nuisance claim against a feedlot for excessive noise. Right to farm laws protect existing operations in many states, but these laws have limits. They typically protect operations that follow good management practices and have not significantly changed their operation. If you are not making good faith efforts to manage noise, you have less legal protection. An attorney who handles agricultural law can explain the specific protections in your state.

How do I measure feedlot noise?

Use a sound level meter to measure noise in dB(A). Take measurements at the source, at the property line, and at the nearest neighbor's property. Measure at different times of day, including feeding times and quiet periods. Record the date, time, weather conditions, and activity for each measurement. A basic sound level meter costs under 100 dollars. For professional grade measurements, hire an acoustic consultant.
