Sound pressure level is the pressure of sound related to a fixed reference. The reference is the threshold of hearing 2 10^-5 Pa, or in the logarithmic decibel scale the value 0 dB.

The table below can be used as a guide to maximum acceptable sound pressure levels in rooms with different types of activities.
