LONG RANGE ACOUSTIC DEVICE (LRAD)
Here is some footage of one of our Long Range Acoustic Devices (LRAD). This is the smallest model of the range the LRAD 100X. It is can be mounted on a tripod as shown here, fitted to a vehicle or boat with a choice of magnetic and vacuum mounts or even carried on your back in its own pack. The 100X is used in a wide range of roles across the emergency services and military. It also has roles in the commercial sector where you need to get a message across clearly fighting background noise. This model will reach out to a maximum of 700m and is crystal clear. It also has an alarm mode that sets of a penetrating siren that will deter protesters, pirates or terrorists. There is an MP3 player fitted that you can prerecord messages on, perhaps the same one in a number of languages.
The first video clip shows it at distance (you can hardly see it) with the sound coming across loud and clear. No one is going to be a say they didn’t hear you message! We then come in a bit closer so that you can see the device close up.
This isn’t a run of the mill old style speaker with an electromagnet pulling a speaker diaphragm in and out. The LRAD system utilises an array of piezo electric tubes that vibrate at two frequencies. These then combine when they strike an object (your listeners ear) to form an audio frequency. This technology enables LRAD to produce a focused beam of sound out to, depending on equipment, 600 metres for the LRAD 100X to 5 kilometres for the LRAD 1950XL, there are a number of different models in-between.
If you’re a thin blue line holding back a crowd of violent protestors, a commander at a fire scene with loud background noise and poor communications, or a Coastguard Rescue Team attempting to get to someone stranded on a cliff in a storm, then this is the equipment you want in your hands.

We will do a piece on the LRAD 450XL next!
