ON THE RESULTS OF EXPERIMENTAL STUDIES OF THE PHYSICAL PROCESS OF GENERATING SOUND VIBRATIONS BEATS IN CLOSED AIR CAVITIES OF TECHNICAL ROOMS

Abstract

This paper gives the results of experimental researches for producing physical processes of acoustic vibration beats, which are spread in a free and in a diffused field of enclosed air volumes in technical rooms of different types. There are defined general regularities and distinct features of forming the physical processes of acoustic vibration beats. A limited frequency range of beats production which includes two different frequency ranges of dynamic frequency interactions with close values of sound frequencies are found out. Sufficiency of frequency detuning of two independent sources of acoustic radiation which exclude physical process creation of sound frequency beats is defined.
