grinding machine noise level
HSE Engineering Health topics: Noise
Below are some examples of typical everyday noise levels and noise levels for a selection of engineering processes where no steps have been taken to reduce noise are given below: Grinding on a pedestal grinder 9095; Discharging metal objects into metal bins 8595 ; General noise level in fabrication shop 8595 ; Hammering steel 95100Levels 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 memorySimulation of Levels of Noise Generated by Local Grinding
