AUDIO SPOTLIGHTING
Audio spot lighting is
a very recent technology that creates focused beams of
sound similar to light beams coming out of a flashlight. By ‘shining’ sound to one
location, specific listeners can be targeted with sound without others nearby
hearing it. It uses a combination of non-linear acoustics and some fancy
mathematics. But it is real and is fine to knock the socks of any conventional loud
speaker. This acoustic device comprises a speaker that fires inaudible ultrasound
pulses with very small wavelength
