There is some confusion regarding the source of the LRAD sound and the frequencies at which this device operates. But don’t worry, we have already done the work for you. If we want to design a system to produce only the warning tone, we won’t have to worry about transmitting the human voice in our design. Learn more about Genasys PSS, Mobile and Public Safety Mass Notification Solutions. It has the capability to be 20 ?
In fact, a typical LRAD system only draws around 100-300 watts, which is well within the range of our home audio or car stereo equipment. If we use this really cool online sweep tone generator and enter the various settings, we can hear that it sounds very similar to our LRAD sound.
LRAD 300X Low Profile Communication Device.
LRAD systems are self-contained or easily integrated with existing communications infrastructure. Optimized to the primary human hearing range of 1 – 5 kHz, LRAD’s advanced driver and waveguide technology ensures every broadcast is clearly heard and understood, even above crowd, engine, and background noise. This unique audio system is considered a non-lethal weapon for this reason.
Now that we have established the source of the soundwaves, we need to begin exploring the design of the LRAD device itself. These reasonable power requirements mean that building a low-cost version of the LRAD system should be feasible. Explore the Video Library and discover how Genasys systems and solutions are used in diverse applications to help keep people safe.
For our first project, we will merely be taking our recorded sounds and testing them with some audio amplifiers and speakers.
Offer the longest range and clearest communication, Provide the scalability, portability and availability needed to communicate in any situation, Overcome background noise in any terrain and environment, Offer simple operations with less manpower, Use much safer alternatives to non-lethal deterrents.
We will get into the design of the LRAD nonlethal weapon system in future articles, but for now, let’s take a look at the annoying sound that it produces. Unlike bullhorns, vehicle P.A. Methods we could use for producing annoying sounds. Our sound source must go through some high power and efficient speakers to produce those levels at long distances. For more information, view our

The LRAD sound is an uncomfortable audible deterrent tone that travels very long distances within a narrow beam of focused soundwaves.
systems and conventional loudspeakers that disperse sound in all directions, LRAD’s proprietary audio technology focuses sound in a 30° beam in front of its Long Range Acoustic Devices (LRADs). Once we understand how to best reproduce the effect of the LRAD in the real world, we can begin thinking about how to make a low-cost version of this amazing technology. Our systems are safe, rugged, reliable, easy to operate and can be temporarily or permanently mounted. This LRAD Mp3 recording can be very annoying and loud, so be careful and never place the speakers next to your ears.

The Long Range Acoustic Device (LRAD) was developed by American Technology Corporation (Now Genasys) and is a popular crowd control tool used by government agencies, law enforcement, and marine companies worldwide. I have analyzed many audio and video recordings of this sound cannon’s output and have also seen the audio reproduced in a downward sweep. This sweep occurs only in one direction and then starts over at 2200Hz, sweeping in that same upward direction over and over. It is a practical and safe alternative to more dangerous methods generally used for crowd control.
Many websites have mistakenly stated that the LRAD produces ultrasound to transmit its beam of deterrence. LRAD mass notification systems are also used to communicate to crowds during large, outdoor events and to populations throughout emergency situations.
LRAD broadcasts are safely optimized to the primary human hearing range of 1 – 5 kHz to generate voice messages that are clearly heard and understood from close range out to 5,500 meters. The Leading Portable AHD for On-Scene and Tactical Communications In addition to featuring best in class broadcast voice intelligibility, the LRAD 100X is 20 – 30 decibels louder than typical bullhorns and vehicle-based P.A. LRAD’s 60°- 360° systems combine warning sirens and highly intelligible voice broadcasts to provide advanced mass notification and public address solutions. Upon further investigation into the source of the LRAD sound, I am fairly certain that the tone is a square wave produced by a simple microcontroller. The good news is that high frequencies do not require that much power to reproduce. Both versions seem to have the same effect. Unfortunately, this app doesn’t repeat continuously, so just keep hitting the “play” button over and over quickly. Pain in the ears begins to occur at 120dB and becomes intolerable over 135dB. LRAD systems deliver live or recorded voice messages with exceptional clarity for any operational scenario. There isn’t anything special about this set of tones or the sweep.
Remotely operated across an IP network to create a fully functional, unmanned perimeter security solution and scalable first response capability. If we look at the spectrum analysis of the audio output from the Long Range Acoustic Device, we can see that the frequencies of sound fall well below the ultrasonic range and are, in fact, within the mid-ranges of normal hearing levels.
LRAD 2000X Long Range Communication Device, LRAD 300X Low Profile Communication Device, LRAD 360Xm Rapidly Deployable Mass Notification System. LRAD Sound. We could use any number of methods to move around various frequencies that would annoy anyone within the path of the audio beam.

It’s just that LRAD was the first company to envision this type of device, so the sound it produces has become sort of the trademarked sound for non-lethal weapons and crowd control devices. The Soundlazer is an example of a device that uses ultrasonic audio to transmit a beam of audible sound capable of bouncing off an object like a laser beam. Designed for integrated applications ranging from small vessels to fixed installation security solutions, the LRAD 950RXL can be controlled remotely across an IP network enabling system operators […] No matter which methods produce this annoying tone, I am sure we would all clear the area very quickly. 2020 © Genasys, Inc. All rights reserved. Frequencies above 2000Hz are still directional when combined with good speaker design.
LRAD systems are self-contained or easily integrated with existing communications infrastructure.
These types of devices are used in museums, kiosks, and retail displays to beam sound to individuals without disturbing others in the same room. We will measure their output and see what kind of results we can achieve. Live or recorded broadcasts from the portable LRAD 100X are heard above crowd and background noise to ensure every message […] CLICK HERE to see inside the LRAD acoustic weapon. Now that we know that there are no unique technologies needed to produce the LRAD sound, all we have to do is come up with a way to generate those tones. If we examine the spectrum analyzer’s output closely, we can see that there are two underlying tones with a continuous upward sweep from 2200Hz (2.2KHz) to 3200Hz (3.2KHz).
You can hear from the video above that it wouldn’t take long for a crowd of people to disperse if you pointed a speaker at them playing that unbearable sound.
This ensures that targeted individuals are able to hear and understand the communications while significantly reducing audio levels behind the devices and in surrounding areas. Add the directional nature of the design of the device, and you have a very effective tool for maintaining law and order. Remotely Operated Security & Response System Engineered and designed on a proprietary pan and tilt system, the LRAD 950RXL is a lighter, more compact version of the successful LRAD 1000RX system. The extremely high power of the LRAD transducer’s outputs also adds to the effectiveness of this system. Before you leave, make sure you're prepared for the next disaster. The sound source is only a small part of the design, and the volume or pressure of the soundwaves it produces are also part of this unique system.
Voice would require a more complex speaker enclosure and drivers to transmit the wider range of frequencies. If you are wearing headphones, make sure you lower the volume before hitting play. LRAD devices boast output levels of 140dB or more depending on the model.
The LRAD sound is an uncomfortable audible deterrent tone that travels very long distances within a narrow beam of focused soundwaves. The warning tones produced by the LRAD are in the normal audible range of hearing and driven by multiple high-efficiency audio mid-range compression drivers. For now, the most straightforward way to do that would be to create an MP3 recording of the sound.
