Abstract
According to the small amplitude acoustic wave propagation in ideal fluid medium theory
the acoustic model of the sound channel of the snail shell-like horn was analysed by using ANSYS to explore the analysis and the improvement of the sound channel of the snail shell-like horn performance.This paper obtains sound pressure and frequency characteristics of the sound channel of the snail shell-like horn.From the energy point of view this paper give the performance evaluation criteria of the sound channel of t...
