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.

Decibel Noise and Range Charts HelpCharts

Decibel (dB) is the unit used to measure a sound's strength. The decibel scale is not linear but logarithmic. This means that noise levels can't be added directly like other numbers. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more

ACOUSTIC PROPERTIES OF INDUSTRIAL MACHINERY

4. What sound levels can be expected during spin test, load test, and field operation. 5. Method of lowering generated sound levels, design absorptions, shielding, etc. Just about everything a person does involves motion. This motion produces “sound.” When machines are built to improve man’s abilities, the situation becomes worse,

How to Make Noise Calculations with Decibels

To state that a certain pump has an 80 dB noise level means that the ratio between its sound level and that of the selected zero base (0 dB) is 80 on the dB scale. The dB Pressure Scale The standard reference base selected for the intensity (pressure) of a sound wave is 0.000,000,003 PSI because this is the least sound wave intensity that can be detected by the average human ear.
