A team of noise specialists from the National Institute for Occupational Safety and Health, Mine Safety and Health Administration, and Joy Manufacturing attempted to evaluate an engineering noise control on a Joy longwall stageloader. The team developed and executed a test plan to evaluate the noise attenuation of the engineering control in an underground coal mining environment. An evaluation of the long-term noise effects and durability of the engineering control were also a focus of the research effort. Pre- and post-control measurements consisting of a combination of worker dosimetry and task observations, tape recordings, and sound level measurements were used to evaluate the engineering control. A description of the engineering noise control, pre- and post-control sound level measurements, and an evaluation of control success are presented. In the end, no evaluation was possible due to mining practices, miner task variations, and inconclusive data.
