There is some confusion regarding the source of the LRAD sound and the frequencies at which this device operates. 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. 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. 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. No matter which methods produce this annoying tone, I am sure we would all clear the area very quickly.

LRAD mass notification systems are also used to communicate to crowds during large, outdoor events and to populations throughout emergency situations. 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. These types of devices are used in museums, kiosks, and retail displays to beam sound to individuals without disturbing others in the same room. 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. Methods we could use for producing annoying sounds. Voice would require a more complex speaker enclosure and drivers to transmit the wider range of frequencies. LRAD’s 60°- 360° systems combine warning sirens and highly intelligible voice broadcasts to provide advanced mass notification and public address solutions. Unfortunately, this app doesn’t repeat continuously, so just keep hitting the “play” button over and over quickly. Frequencies above 2000Hz are still directional when combined with good speaker design. 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. 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 […] 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. The focused beam of sound is possible through a unique design that combines folded horn speakers within a large parametric array. The frequency of the sound starts at 2200Hz and sweeps up to 3200Hz in a matter of a few hundred milliseconds.

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). It has the capability to be 20 ? Pain in the ears begins to occur at 120dB and becomes intolerable over 135dB. This sweep occurs only in one direction and then starts over at 2200Hz, sweeping in that same upward direction over and over. This LRAD Mp3 recording can be very annoying and loud, so be careful and never place the speakers next to your ears. Remotely operated across an IP network to create a fully functional, unmanned perimeter security solution and scalable first response capability. These reasonable power requirements mean that building a low-cost version of the LRAD system should be feasible. Before you leave, make sure you're prepared for the next disaster. 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. PRIVACY POLICY. 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. | Privacy Policy, A Unified Communications Platform for Disasters and Emergencies, Critical Communications Solutions for the Public and Businesses, Emergency Warning and Notification Speaker Systems. LRAD devices boast output levels of 140dB or more depending on the model. But don’t worry, we have already done the work for you.

Our systems are safe, rugged, reliable, easy to operate and can be temporarily or permanently mounted. Add the directional nature of the design of the device, and you have a very effective tool for maintaining law and order. 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. 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. 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. LRAD 2000X Long Range Communication Device, LRAD 300X Low Profile Communication Device, LRAD 360Xm Rapidly Deployable Mass Notification System. 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.
