What is the 3dB rule?
3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). … It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.
What is the loudest sound ever recorded on Earth?
