This document describes standard procedures and recommendations for effective pure-tone audiometry carried out in most audiological contexts. It also includes descriptors for pure-tone audiograms and the recommended format for audiogram forms. This document is not intended to provide guidance on specific circumstances or on interpretation of results. It is important that the competent person carrying out, or responsible for, the test (the ‘tester’) uses professional judgement when deciding on the particular approach to be used with each person being tested (the ‘subject’), given the specific circumstances and the purposes of the test, and the tester’s level of competency. The BSA has produced a separate procedure for the determination of uncomfortable loudness levels (BSA).
