THE MEASUREMENT AND ANALYSIS OF WORKING CONDITIONS REGARDING NOISE AND PREPARATION OF NOISE CONTOUR MAP IN A TAG AND TRANSPONDER PRODUCTION FACTORY IN LAMPHUN PROVINCE

Abstract

This study aims to assess the noise level in the working environment to create a noise contour map and designate areas for personal protective equipment in a tags and transponder manufacturing factory. The research involves measuring and analyzing the work environment is noise conditions in three areas using a sound level meter standardized by IEC PUB 651 TYPE 2. The results were used to create a noise contour map and designate areas for personal protective equipment. The study found that in area 1 (EMB department), the average noise level was 78.03 dBA, in area 2 (Injection molding department), it was 75.45 dBA, and in area 3 (RF machine department), it was 70.99 dBA. Overall, the majority of measured noise levels complied with standards, but area 2 had one point with noise exceeding standards, at 85.1 dBA, representing 0.52% from a total of 191 measuring points in the said area it has a maximum sound level of 85.1 dBA. Therefore, area 2 should be designated for protective equipment, along with monitoring and assessing noise exposure and measuring additional accumulated noise level, together with control planning at the source of the sound or transmission paths should be implemented to reduce potential health impacts on employees. This includes establishing safety regulations, providing training about the dangers of loud noises and creating noise contour maps to raise awareness and foster a healthy working safty environment for employees.
