Long Range Acoustic Device

The Long Range Acoustic Device ( LRAD ) represents the new generation of wildlife control devices . the LRAD system is capable of providing controlled delivery of bioacoustics at variable volumes in a flight beam at range to 2000 meters , and max noise level to 160dB . The LRAD drive device also named High Power Directed Acoustic Generation , it is a flat panel ,multi-transducer, phase coherent emitter. designed for broadcast high power alarm notice .

The product firmly and durable with good quality suitable variable environment, can properly work by all weather, and enhanced voice and tone and frequency response, it is non-deadliness weapon. With effective directed noise generation technology, it will not injure the operator .

Application:

*Bird control for airports, airfields, landfills, mines & wind farms.

*Waterside force protection

*Crowd & Riot control

*Building clearing operations

*Psychological operations

*Visit board search & Seizure

*Remote-operation infrastructure force protection

*Ground/mechanized offense/defense operations.

Principle of Operate:

Long Range Acoustic Device work principle like Antenna array, arrange multi acoustic unit which can generate high power acoustic on a round flat panel, it make up a surface acoustic base array, and use the acoustic supraposition principle to focusing and direct the voice . the Acoustic unit use electroacoustical transducer, and the character is big power ,convert efficiency high, small dimension, and with small heat emitting . signal source and amplify circuit control the phase coherent emitter, and based on the supraposition principle, the large acreage transducer array generate narrow acoustic beam, so that the acoustic power source directed emitting .

Product Specification:

Highly directional communication at 2000 meter

Carry and install easy , Can quickly install in everywhere

Support Microphone , MP3 etc multi audio input method, and can broadcast various kinds lifelike voice .

One operator is enough and the back of product is safety area

Suitable for all weather .
