| Research Abstract |
The purpose is an methodology for building a small acoustic space that produces little audible sound at the intersection of multiple ultrasonic beams. We introduced a method that makes a phase difference between two transducers arranged side by side 180 degrees in a cluster of transducers. We made good progresses in three methodologies(1) particularly reduce the sound out of the acoustic space,(2) weaken the strength of sound by transducers in a concentrate circle, and(3) focusing ultrasonic beams inside of the strait line, and in their multiple effects.
