WEBINAR - ACGIH® TLV® for Audible Sound – Understanding the Proposed Notice of Intended Change to the ACGIH® TLV® for Noise


Occupational noise exposures represent an important but under-recognized cause of disease and disability in the United States. Now titled as Audible Sound, the ACGIH® Threshold Limit Values for Physical Agents (TLV®-PA) Committee has proposed a revision to the TLV® for Noise. This webinar will highlight the available information on sources and trends of occupational noise exposures in the U.S., discuss the elements and recommendations in the draft Notice of Intended Change (NIC) TLV® Documentation, including a review of the proposed notes that link occupational noise exposure to increased risk of cardiovascular disease (including hypertension and ischemic heart disease), as well as increased risk of occupational injuries. The list of chemicals indicated as ototoxic, even in the absence of noise, has also been expanded in the draft NIC TLV® Documentation. This webinar will also review the recent scientific literature cited within the draft NIC Documentation supporting the addition of notes and expansion of the list of ototoxic substances, and will also cover best practices and available resources for the prevention of occupational noise-induced hearing loss. Participants will receive a copy of the proposed NIC Documentation for Audible Sound with their registration (a $60 value).

What is an ACGIH® Webinar?

ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. This ACGIH® webinar is 1 hour in duration and consists of a live presentation given via the Internet with an audio telephone link similar to that of a conference call.

Audio Option

ACGIH® is pleased to offer webinar attendees an audio option. U.S. and Canadian attendees can connect to the audio portion of the webinar via the toll-free audio telephone link or listen to the audio portion through an audio stream directly through their computer. Other international participants can listen via the audio stream without incurring additional telephone charges.*

*Connection from outside the U.S. and Canada will be via streaming audio only.
