Long Range Acoustic Device (LRAD)
I would like to know about how this device operates from the engineering folks out there. I just don't have the knowledge to understand how it works. I'm used to using an Amp to power my speakers. IIRC, it takes a doubling of power to increase sound by 3db. Being exponential in nature, it would take tons of power to get to these levels they are talking about (above 130db) for distances the distances they say which can go up to 300 meters for the short bursts.
Can someone educate me on this and offer opinions and what effects this could have on the speakers of the future?
