Interface Analysis in Personal Protective Equipment
Noise is a harming agent to the human hearing and is present at every work ground, be it an office or a metallurgic plant. This paper is centered in the analysis of noise levels and their relation with the most common work related illness, the Noise Induced Hearing Loss (NIHL) as well as the analysis of auricular Personal Protective Equipment (aPPE), which has been reported to lose efficiency through its life span. From all the gathered data are proposed changes in the overall structure of the insertion type of hearing protectors. T o come up with such conclusions the study discourses on the efficiency of aPPEs currently employed in high noise levels work places. If considered the daily use, the efficiency of auricular protectors falls below the required attenuation in a matter of days. Also, is presented the issue of the non-use of the protector, for it being uncomfortable. The authors propose the action of a products designer, with backup of a materials engineer, in the selection of a new material to be used in the making of the protectors. The standardization between manufacturers, as to encourage the use, is suggested as well. The paper is concluded with the notion that modifications are needed in order to improve functionality and cost benefit ratio, important as much for the worker as for the company he is working for.
