20 kHz, the frequency response of the sound level meter should be good, with variations smaller than 1 dB, over that incident sound pressure of amplitude 1 Pa (94 dB) at 1000 Hz. It can also be expressed in decibels by the .. output amplifier. The instruction manual of the measuring instrument should be consulted.
