Sound-absorbing and insulating enclosures for ultrasonic devices reducing the level of noise penetrating the environment. Own research results

Summary/Abstract: The article discusses the technical solutions of sound-absorbing and sound-insulating enclosures for devices that are sources of ultrasonic noise (sound frequencies range of 10-40 kHz). Due to the high health risk of employees operating ultrasonic technological devices and the fact that they are in close proximity to these devices, it is necessary to use an effective measure to reduce this risk, i.e. sound-insulating enclosures. So far, however, the rules for the use of such casings and the sound-insulating and sound-absorbing properties of their materials (in this frequency range) have not been defined. The article presents the results of own research on the impact of the materials used to make enclosures, linings of casings and the presence of openings (hole) in casings on the level of noise emitted by ultrasonic devices that penetrates into the environment.
