Abstract: In this paper, we propose an experimental installation in the form of a laboratory bench for measuring the spectral characteristics of noise, the effectiveness of sound-proofing screens and individual human audiograms. The stand contains a noise source in the form of a low-frequency sound generator, a loudspeaker, headphones, a sound-proofing screen and a sound level meter. The installation allows to investigate noise experimentally depending on the amplitude and frequency of the spectrum. In this case, you can select the form of the noise signal, select or check the sound-insulating screens of various materials, as well as receive individual hearing audiograms for employees. The installation can find application in scientific research and educational process.
