Establishes procedures and requirements for air conduction pure tone threshold audiometry without masking that are applicable to individuals whose hearing sensitivity might be adversely affected by occupational noise exposure. Covers references, definitions, audiometers, conditions for audiometric test rooms, preparation and instruction of subjects before audiometric testing, conduct of audiometric test and determination of hearing threshold levels from an audiometric recording and audiogram.
