INNOVATIVE APPROACHES TO DESIGN OF PROTECTIVE NOISE CABINS BY APPLYING WALL MATERIALS

Abstract

The paper presents a practical solution for designing a protective noise cabin using wall materials and a mobile access application. Due to the current wide-spread demand for small-sized benchtop tools intended for domestic purposes, the development of group protective equipment for their upgrade, operation, and application becomes urgent. The presence of adjacent living rooms when organizing the working space at the stage of set-up works raises the issue of meeting the requirements of sanitary standards concerning noise. The concept of designing a cabin with a sufficient level of noise insulation is implemented by the example of the most unaffected soundproof cabin made of purest wall materials. Processing of results on the average value of sound pressure levels and indeterminacy of measurements is carried out using the developed mobile accessed application. It has been determined that the sound level (dBA) is increased with the increase of the rotational frequency. The achieved maximum level of the sound outside the protective noise cabin of 73.6 dBA at the standard mode of equipment operation is lower than the regulated value of 80 dBA, thus allowing to substantiate this approach as the express method for designing a protective noise cabin.
