Audiometric Calibration and Standards: Methods for Audiometry
The ISO 8253 series which specifies audiometric test methods, have now all been adopted as dual numbered BS EN ISO standards. In addition, ISO 6189-BS 6655 deals with pure-tone air conduction audiometry used for hearing conservation purposes.
