scope:

A Guide for the Control of Audible Sound Hazards is a downloadable guide published by ACGIH and the Threshold Limit Values for Physical Agents (TLV-PA) Committee. This guide is designed to provide additional guidance for users of the Threshold Limit Value (TLV) for occupational exposure to audible sound, which recommends levels of exposure and conditions under which it is believed that nearly all healthy workers may be repeatedly exposed, day after day, without adverse health effects. It is important that this TLV be applied only by individuals adequately trained and experienced in the necessary measurement and evaluation techniques.
