ABSTRACT:
A pre-recorded test tape or test disk which is used to isolate unwanted buzzes in an audio listening environment. The prerecording is a series of varying amplitude frequency sweeps. The frequency sweeps from the audible range of 20 Hz. to 400 Hz., while the amplitude level is set at five different levels. The amplitude of the first sweep is set to the maximum output of the audio system which will give a clean 400 Hz. pre-recorded pallet tone. Each subsequent sweep is 6 dB down from the previous sweep.
