Study Regarding Industrial Noise Reduction with Sound Absorbing Screens

Abstract

To establish a coherent, realistic, and tangible effects strategy on the workplace environment, it is necessary to know the industrial noise level and characteristics. The noise is the main risk in the case of occupational illnesses of the hearing loss type given that all workers must be protected. The realized determinations showed an acceptable value of the noise attenuation coefficient for screen less than 0.1 m thick. Also, their utilization can decrease the acoustic pressure from 9% to 35%, the reduction depending on screen thickness. Reduced weight, the different geometries of realizing and assembling (with the scope to extend the surface covered by them), suggest that they be used to improve the work environment.
