Isolating the worker from the noise source in a room or booth (such as a sound wall or windows).The same is true of decibels. Although rarely explicitly mentioned, decibels are always in reference to a chosen value. Every time you come across the word decibel, you can tack on “with reference to _____”. Without a reference, a decibel is meaningless. For sound pressure, the reference value is generally 20 micro-Pascals.Sound levels are measured in A-weighted decibels. Long-term exposure to sounds below 80 decibels should not affect your hearing. Sounds measured at this level appear as OK in the app. Repeated, long-term exposure to sounds above 80 decibels can lead to permanent damage.

Each 10 dB represents a factor of ten difference, so 120 dB represents a pressure 1,012 times greater than the reference threshold level. Ears respond logarithmically to changes in sound level, explaining why the decibel is a useful tool of comparison. ...The decibel scale is logarithmic, meaning it increases by the power of 10 each time. The smallest audible sound is 0 dB.
