Australia Model Code of Practice Managing Noise and Preventing Hearing Loss at Work 4.2: Have noise assessments done by a competent person under AS/NZS 1269.1, with understanding of the assessment objectives, the physics of sound, instrument use and limits, exposure determination methods, recording and explaining results, hearing protector evaluation, when to call in a specialist, and the applicable law and standards

What does 4.2 require?

Whoever assesses noise should be competent and should follow AS/NZS 1269.1 on measuring and assessing noise immission and exposure; the harder the situation, the more knowledge and experience the assessor needs. Competence here means being able to show a thorough grasp of what the assessment is for, the basic physics of sound, how to use the measuring instruments properly and where their limits lie, what information and methods are needed to work out occupational exposure, how to record results and explain them to people on site, how hearing protectors are evaluated, when a specialist in noise measurement or control should be called in, and the Australian legislation, codes and standards that apply, together with a basic understanding of how hearing works, how noise harms it, and the principles of engineering noise control and noise management.
