STAND FOR THE STUDY OF SOUNDPROOFING MATERIALS
The article presents information about the stationary robotic stand designed for experimental research, describes the work of this stand. A feature of the stand is the implementation of a research installation with the possibility of programmatic performance of research without the mandatory presence of the researcher. A remotely controlled power amplifier, a remotely controlled sound generator and a personal computer with special software are used. The sound source is located near one of the end walls of the soundproof chamber. The sound receiver in the form of a high-precision microphone is located at the opposite end wall of the soundproof camera and is connected to the sound processing module, which is connected to a personal computer. The developed stand is an example of the concept of robotic research, the direction of improving the methodology of research work. A description of the design of the stand is given, information about the known similar research equipment is given. The scheme of the stand and a description of its construction are given. Some results of studies of soundproofing materials are given. The influence of the structure of soundproofing materials on the frequency characteristics of acoustic resistance is shown. The essence of booth automation is to programmatically change the research modes for each experience. The robotic stand ensures the reliability of the results of experimental studies, allows you to speed up the results.
