Abstract

One of the main problems of pneumatic systems is the noise that occurs when compressed air is discharged, which negatively affects personnel. To create an effective noise muffler, it is necessary to predict its throughput. The article presents the results of experimental studies of the bandwidth of a noise muffler using porous polypropylene. A simulation model of a noise muffler as part of a pneumatic system has been created and calculations of pressure changes at control points have been carried out. Noise measurements were carried out and the acoustic efficiency of the developed muffler was determined, which amounted to 34.3 dBС and 32.4 dBА.
