Simulation of Levels of Noise Generated by Local Grinding

Feb 06 2012 Levels of noise generated from grinding machines were measured. Noise levels as high as 116dB was obtained. These levels of noise can be stressful that can result to fatigue. It is capable of causing temporary and permanent deaf. Noise spectra generated from grinding machines are mixture of low and high frequencies. Low and high frequencies noise can have negative effects on memory.
