Abstract

One of the problems of acoustics is the sound attenuation. In this paper this problem was described on the basis of changes in sound structure during transmission through pregnant women’s abdominal wall. This phenomenon can be modeled with first order low-pass filter. In this paper, changes in amplitude and phase characteristics of the sound, which reach to the fetus ear, and changes in sound timbre have been shown.
