For the non-specialist, audiometric testing can seem like a confusing minefield so this is a quick breakdown covering what is the minimum which is acceptable for standards-compliant audiometry. When we say an audiometric test is ‘compliant’, what do we mean? There are two documents setting out standards for a screening audiometric test: BS EN ISO 8253 …

The employer must establish and maintain an audiometric testing program. The important elements of the program include baseline audiograms, annual audiograms, training, and followup procedures. Employers must make audiometric testing available at no cost to all employees who are exposed to an action level of 85 dB or above, measured as an 8-hour TWA.

§ 227.111 Audiometric test requirements. (a) Audiometric tests shall be pure tone, air conduction, hearing threshold examinations, with test frequencies including 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. Tests at each frequency shall be taken separately for each ear.

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 …
