Formation of Given Sound Field by Modeling Sound Reflecting Surface

Abstract

A model of a sound reflecting surface is presented that provides the specified character of the sound field formation. According to the pre-planned nature of the sound field for a specific area, the shapes of the reflecting surfaces are modeled, made and installed in a given order. For a point sound source, the shape of the reflecting surface is calculated, which is located at a given distance from the source and ensures the formation of a parallel sound stream in a given direction.
