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.


However, noise levels above 7580 dB (A) are known to cause hearing damage. The louder the noise is, the less time it takes to cause damage. For example, noise levels at 85 dB (A) may take as long as eight hours to cause hearing damage, while noise at 100 dB (A) …
