Sound deterrents provide a safe way to protect your property without causing permanent harm.
Basic systems include electronic guard dogs that bark as loud as 120 decibels, while advanced devices like LRADs can reach 160 decibels. These tools create high-pitched sounds between 19,000-20,000 hertz that make intruders feel uncomfortable and want to leave.
Before installing any system, check your local noise laws and follow all safety rules carefully. Adding motion sensors and cameras to your sound deterrents will make your security even stronger.
Take time to research different models and safety guidelines to find the right system for your property.
Understanding Sound Deterrent Technology
Sound deterrent technology has come a long way in recent years. At its core, it creates strong sound waves that make intruders uncomfortable.
Modern devices like Long-range Acoustic Devices (LRADs) can make sounds as loud as 160 decibels – as loud as a shotgun firing right next to you. Electronic guard dog systems have also improved, creating realistic barking sounds up to 120 decibels to scare away unwanted visitors.
These systems use groups of smaller speakers to send special sound signals through the air. They work really well because they can make different types of sounds, including very high-pitched ones between 19,000-20,000 hertz. Engineers design these sounds to make people uncomfortable without causing lasting harm.
What makes these devices smart is how they use different deterrent tones that spread out in the air. The air changes these sound signals to make them work better at keeping intruders away.
While some people try to protect themselves from these sounds, most methods don't work very well. Even good noise-canceling headphones can't block out these powerful sound waves completely. Simple materials like cardboard might lower the sound by about 80%, but you can't count on them to block the sound entirely.

Installation and Maintenance Requirements
Professional installers must set up and maintain non-lethal sound deterrents to work properly. You need to connect the device to your existing alarm panel's 12v power supply, which lets you integrate it easily without extra batteries.
The motion detection system lets you adjust sensitivity to prevent false alarms while keeping your area secure.
To make sure your device works well and stays safe, follow these key steps:
- Place the device where sound won't bounce off walls, so it covers your security area directly without bothering people walking by
- Hook up the unit to a steady 12v power source and check that all electrical connections are safe
- Put the deterrent at the right height and angle to cover the most area without exposing the wrong places
- Add weather protection that fits your local climate to keep the unit safe from rain, snow, or sun
Check your device regularly to make sure it works, especially after bad weather or if something hits it. Test the sound level often to make sure it's still putting out the right volume.
When you follow these setup rules and keep checking your sound deterrent, it will work better and stay within safety rules longer.
Legal Compliance and Regulations
You need to check your local noise rules and get permits from city officials before setting up any sound deterrent system on your property.
When you combine deterrents with home security alarms, you create a better system to protect your property.
Law enforcement requires you to register powerful sound devices, and you must keep proper documents ready for their regular checks.
Follow the maker's safety rules carefully – this includes sound levels, how long you can use the device, and where you point it. This helps you avoid legal problems and keeps everyone safe.
Noise Ordinance Requirements
You must follow strict noise rules when using sound devices to protect your property. These rules include both local noise laws and federal guidelines.
Most local rules limit how loud sounds can be to protect people's health and keep neighborhoods peaceful. You should know both OSHA safety rules, which say workers need ear protection for sounds over 85 decibels, and what your city requires.
To follow noise rules correctly, you should:
- Look up your local noise laws and get permits before setting up any sound systems
- Check and write down sound levels to make sure they stay within legal limits
- Put up warning signs and give out ear protection when sounds might go over 85 decibels
- Keep good records of when you use the system and how loud it gets
Courts have made decisions that limit how people can use very loud devices like LRADs. Groups of hearing experts, like Audiology Australia and the American Speech-Language-Hearing Association, strongly support following these rules.
If you don't follow local, state, or federal rules, you could face fines or legal problems, so it's important to make sure your sound system follows all the rules.
Registration With Authorities
Local authorities require you to register your sound deterrent system in most areas. You must work with police and regulators to make sure your sound security equipment follows all safety rules and laws.
Before you set up any sound deterrent system, you need to submit papers that show you follow local rules. These papers should include:
- Proof that operators are trained
- Your safety rules
- Your plans for using the devices
Many areas now watch these systems closely because of recent court cases, especially in New York, where they limit how people can use LRADs (Long Range Acoustic Devices).
Safety warnings from expert groups have made registration rules stricter, so you need to know what rules apply in your area. Whether you work in Australia, New Zealand, or other places with new rules, you must keep up with changing safety requirements.
When you register, you need to explain:
- How you'll handle health risks
- Limits on how you'll use the system
- What you'll do in emergencies
Remember: If you don't register your sound deterrent system properly, you could face fines and have to stop using it right away.
Safe Usage Guidelines
Safe Usage Guidelines
You need to follow strict safety rules after registering your sound deterrent system. Following safety rules protects you from legal issues and ensures you meet all regulations.
These rules help prevent hearing damage and other injuries when you use the system.
Follow these key safety steps when using sound deterrents on your property:
- Keep track of sound levels – don't let them go above 120 decibels for more than eight seconds, since this can permanently damage anyone's hearing in the area
- Put up warning signs around your property to tell visitors and potential intruders about your sound deterrent system
- Keep detailed records each time you use the system, including how long it ran, how loud it was, and why you turned it on
- Write down clear steps for safe use, including how far people should stay away, how long the system can run, and how to shut it off quickly if needed
Make sure to check and update your safety rules often to match current laws and expert advice.
Courts have set limits on how people can use sound devices, so you must prevent harm to anyone near your property, including people passing by and emergency workers who might need to enter.
Performance and Effectiveness Metrics
Sound deterrents work best when we measure two main things: how loud they're and what sound frequencies they use. Professional LRADs can be as loud as 160 decibels – about as loud as a shotgun fired nearby.
Indoor systems usually run at 122-124 decibels, which works well without damaging buildings. Like other sound alarms, these systems let users adjust how sensitive they are.
Volume isn't the only thing that matters – the sound frequencies also play a big role. Using different tones together makes people feel more uncomfortable, which helps keep them away. High-frequency sounds between 19,000-20,000 Hz target specific areas well, though older people mightn't hear them as clearly as younger people do.
Safety needs to balance with how well the system works. Sounds over 120 decibels work better to keep people away, but they can permanently damage hearing even after a short time. This means we need to check sound levels often to make sure the system works well while keeping everyone safe, including nearby people and security guards.
Training for Security Personnel
Security staff must complete thorough training to operate LRADs safely, focusing on correct power levels and time limits to avoid causing permanent hearing damage.
Staff need to know how to use safety equipment properly and understand how sound waves spread, which helps protect both operators and nearby people.
Teams must set up and watch clear safety zones, making sure the sound only affects the intended area and doesn't harm civilians who happen to be close by.
Safe Operating Procedures
Security professionals must complete thorough safety training before operating non-lethal sound deterrents to protect everyone's hearing. Learning how to use high-pitched sound devices safely is crucial since they can be louder than 120 decibels.
You need to learn the right setup methods to reduce sound bounce and keep everyone safe.
Follow these key safety steps when using a deterrent device:
- Look around for any surfaces that could bounce loud sounds back at you or your team
- Stay at least 10 feet behind the device and wear proper safety gear, including sound barriers
- Keep track of sound levels to make sure they stay under 90 decibels during high-frequency use
- Switch between different settings as needed, always starting with the lowest power that works
Thin cardboard and special foam can help block sound, but don't count on these materials alone to stay safe.
Your security or police training should stress that even non-lethal tools need careful handling to avoid hurting anyone's hearing.
Protective Equipment Requirements
Security personnel need proper protective gear meeting safety standards before using any non-lethal sound deterrent. You must wear ear protection that cuts sound levels by at least 20-30 dB to protect your hearing when working with LRADs.
High-quality noise cancellation headphones are a must since they protect against dangerous sounds over 120 decibels. While thin cardboard can slightly block high-frequency sounds, don't count on it as your main protection.
Regular items like hoodies or acoustic foam won't protect you enough against LRAD sounds.
Pay attention to your surroundings when using sound deterrents. Keep sound from bouncing off nearby walls to avoid accidental exposure and headaches.
Stay up to date with training to learn the latest safety rules and how to use equipment correctly. Your protective gear protects you from health risks like blown eardrums and hearing loss that won't heal.
Check your gear carefully before each use to make sure it works properly.
Dispersal Zone Management
Managing Dispersal Zones with LRADs
Security teams need to understand both the benefits and dangers of Long Range Acoustic Devices (LRADs) when controlling crowds. These powerful sound systems can help manage large groups, but they must be used carefully to avoid hurting people.
Key points for safe and effective LRAD use:
- Sound Settings
- Use alarm mode between 2,200-3,200 hertz
- Use high-frequency mode between 19,000-20,000 hertz
- Pick the right setting based on each situation
- Safety Limits
- Sounds over 120 decibels can permanently damage hearing
- Sounds at 150 decibels can break eardrums
- Keep sound levels below these dangerous thresholds
- Sound Bounce Control
- Watch out for sound bouncing off buildings and hard surfaces
- Reflected sound can cause headaches and discomfort
- Choose locations that minimize these echoes
- Protection Facts
- Regular headphones won't block LRAD sounds well
- Even noise-canceling headphones offer little protection
- Tell team members about these protection limits
Control the LRAD's focused sound beam carefully to protect protesters, nearby people, and security staff.
Check the surroundings and target specific areas instead of broadcasting widely.
