Audio spotlighting was invented by Dr. F. Joseph Pompei and uses ultrasonic waves to produce focused beams of sound. It allows sound to be focused only in a specific location using thin, flat ultrasonic emitter devices. Audio spotlighting can precisely control sound dispersion and travel much faster than conventional speakers, promising to replace them. It puts sound exactly where wanted and will shape the future experience of sound applications.

3.  Audio Spotlighting was invented by Dr. F.
Joseph Pompei.
 Production of focused beams of sound.
 Uses ultrasonic wave as carrier signal
 Non-linearity of the air aid the device for its
working.

5. (Speech or music)
(21k to 28k Hz)

9.  Direct Mode
 Projected Mode

10. 1. Can focus sound only at the place you want.
2. Ultrasonic emitter devices are thin and flat
and do not require a mounting cabinet.
3. Focused sound travels much faster in a
straight line than conventional loudspeakers.
4. Dispersion can be controlled - very narrow or
wider to cover more listening area.

13. Audio spotlighting system holds the promise of
replacing conventional speakers.
It allows the user to control the direction of
propagation of sound.
Audio spotlighting really “put sound where you
want”.

14. Audio spotlighting system is going to shape the
future of sound and will serve our ears with
magical experience.
So we can conclude- Audio Spotlighting really
“put sound where you want it” and will be
“A REAL BOON TO THE FUTURE.”
