Noise Exposure Assessment at Wood Workshop Faculty of Bioengineering and Technology University of Malaysia Kelantan, Jeli Campus

Abstract

Loud noises from the machinery significantly harm the workers at wood workshops. It is critical to consider the loud surroundings they experience, the effect on their hearing, and their general well-being. This study will improve methods for reducing the health risks associated with noise exposure at work. This investigation is being conducted at UMK Jeli's wood workshop at the Faculty of Bioengineering and Technology. A sound level meter and calibrator were the tools that were employed. For the assessment, nine sampling points were used. The selection of the points was based on the types of machinery that produced noise, including the Flat Die Pallet Mill (P1), Sliding Table Saw (P2), Thicknesser Planner (P3), Band Saw (P4), Air Compressor (P5), Jaw Crusher (P6), Pulverizer (P7), Grinding Machine (P8) and CNC Router (P9). As a result of the loud machinery, 4 out of 9 points had noise levels above the permissible limit which is NEL>85dB(A). At 98.3 dB(A), the Flat Die Pallet Mill (P1) produced the most noise. Based on the assessment, we also achieved that 8 out 9 machines were exceeding the excessive noise limit which is NEL>82dB(A). The next step in this investigation after the data were collected is to draw the noise mapping for every machine evaluated during area monitoring was. The mapping of noise was effectively established. The mapping can be used to know the noise hazard area that produced from the machineries. The noise mapping was successfully established. This research also successfully determined that the worker was exposed to noise level exceeding the recommended safe limit of 85dB(A).
