Performance of the Ear Piece about Sound Collecting

A Study on a Sound Reflector Type Ear Pieces for Tuning the Acoustic Environment for Music (part1)

Abstract

Abstract : In this research, acoustic measurements were carried out to investigate performance of the ear pieces about sound collecting. The ear piece has a paraboloidal reflector focusing on the ear canal. The influences of area and position of the reflector and of the distance between the ear canal and the reflector on the performance were investigated.
The results are as follows; 1) Sound collecting performance increased as the area of reflector became wider. 2) The performance decreased as the distance between the ear canal and the reflector increased. 3) The performance was not affected by positions of the reflector.
