HEARING LOSS PREVENTION: HEARING PROTECTION AND AUDIBILITY CONSIDERATIONS FY06

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.
Current Information can be found at: Hearing Protection and Audibility Considerations - FY07

Objective

  • To develop recommendations and strategies for mine operators and mineworkers that will improve the audibility of spoken communication and hazard/warning signals in the mining environment while preventing additional cases of noise-induced hearing loss.
