Sound level meters trade average level against tracking speed via time response.
Evidence
Thus most sound level meters have slow and fast time response settings. The slow time response gives an estimate of the average sound level whereas the fast response tracks more rapid variations in the sound pressure level. — David Howard, Jamie Angus, coustics and Psychoacoustics, 627
