Test frequencies in audiometry are derived from the musical scale, and are generally octave intervals. An octave is a tone with a frequency that is exactly twice that of a reference tone. Therefore, the basic audiometric test frequencies are 500, 1000, 2000, 4000, and 8000 Hz.

Results of the audiometric testing program must be evaluated to determine if the tests are valid and if there is a change in hearing that requires follow-up action. The OSHA definition of Standard Threshold Shift (STS) in regulation 1910.95 is a change in hearing of an average of 10 dB or more when comparing the current test to the annual test at the frequencies of 2000, 3000, and 4000 …

Audiometric Symbols - ASHA
https://www.asha.org/policy/GL1990-00006/
Audiometric symbols used to record the results of conventional pure tone threshold audiometry were suggested by ASHA ( 1974), following a review by the Committee on Audiologic Evaluation. Jerger ( 1976) has described further options in the way audiometric data might be reported in scholarly publications. Many audiometric symbols are used universally, while others are unique …
