Overload/Under Range Conditions A secondary role of calibration is to determine the sound level which would overload the instrument and the minimum sound level which can be accurately measured, referred to as the under range level. It can also be expressed in decibels by the following expression: Thus, a microphone giving an output signal V of 10 mV for a pressure signal p of 94 dB has a sensitivity of 10 mV/Pa or -40 dB.
