Grinding Machine Noise Level

  • HSE Engineering Health topics: Noise

    Choose tools carefully. E.g. using a 30 x 6 mm tool instead of an 80 x 6 mm tool for a ‘slitting’ operation may reduce the noise level by up to 5 dB (A). As a general rule, the smaller the surface area of the tool, the lower the noise; Carry out periodic inspections and necessary maintenance on machines and noise control measures, to ensure

  • Simulation of Levels of Noise Generated by Local Grinding

    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.

  • Safe Environments Common Noise Levels

    Noise is the variation of air pressure comprising compressions and rarefactions of longitudinal waves. It is the magnitude of the compressions and rarefactions that determine the noise levels. As the noise level increases the risk of Noise Induced Hearing Loss (NIHL) increases. A person can generally perceive a 1 3 dB change in noise levels.

  • How to Make Noise Calculations with Decibels Womack

    Example: If noise from Pump 1 is 85 dB, and Pump 2 is added with 90 dB, what will be the new noise level? Solution: 90 85 = 5 dB difference. Use the chart: Add 1.2 dB + 90 dB = 91.2 dB. In combining several noise sources, combine the two highest first. Combine this total with the next highest level, etc.

    Sound Level Meters; Sound level meters provide instantaneous noise measurements for screening purposes (Figure 16). During an initial walkaround, a sound level meter helps identify areas with elevated noise levels where full-shift noise dosimetry should be performed. Sound level meters are useful for: Spot-checking noise dosimeter performance.
