Noise monitoring in CNC machine working area in electronic based company in Kuantan, Malaysia

Noise is the most significant health hazard to the working population in terms of the number of people affected has been recognized by the World Health Organization (WHO). The noise induced hearing loss is the most cases damage accumulates over time. Therefore, the goal of noise control regulation f...
