of surveying). Stakeholder interaction is enhanced through the Noise Partnership group, previously mentioned. It appears that the Noise Partnership is heavily focused on coal mining noise. If this is the case, it should be expanded to include metal and nonmetal mining.

Signature Accomplishment: Education and Training Through Mobile Audiometric Testing

The Hearing Loss Prevention Unit (HLPU), developed by the Mining Program, consists of a sound-insulated 32-foot trailer containing four independent, computer-controlled audiometric testing stations. The HLPU travels around the country to conferences and to remote mine locations educating miners and their families about noise-induced hearing loss and hearing protection. Not only can it conduct hearing evaluations, but it is also used by the Mining Program for training—such as teaching workers the proper way to insert hearing protectors—and for research projects. A counseling area inside the booth contains audiovisual equipment used to present educational materials. The HLPU can be configured to perform a wide range of research tasks, including hearing test feedback as part of training programs, training in proper use of hearing protectors, and supporting more effective hearing loss programs aimed at protecting the hearing of the nation’s miners.
