A Story of Impact:
Job-induced hearing loss is a big problem in today’s work settings, affecting workers in industry sectors such as manufacturing, construction, mining, transportation, agriculture, and the military. Approximately 22 million workers are exposed on the job to noise levels that could harm their hearing.
The National Institute for Occupational Safety and Health (NIOSH) has developed the NIOSH Hearing Loss Simulator, a software training and communication tool that demonstrates the effects of noise exposure on a worker’s hearing without exposing the person to harmful noise levels or toxic materials. The software considers several factors including age, gender, level of exposure, and years of exposure, and then simulates human speech that is degraded to reflect the estimated hearing loss.
Relevant Information
- At present exposure limits, 1 in 4 people exposed to excessive noise or other toxicants while on the job will develop permanent hearing loss.
- Approximately 11.4% (13.9 million) of working American adults report some degree of hearing loss.
- Hearing loss may impede some individuals’ ability to be gainfully employed.
- Hearing loss is not inevitable and can be prevented.

NIOSH Recommendations
- Download the free NIOSH Hearing Loss Simulator. www.cdc.gov/niosh/mining/products/product47.htm.
- Read the NIOSH Hearing Loss Simulator Instruction and Training Guide. The guide details the simulator’s functions, lists the major objectives that can be addressed with the simulator, and provides training scenarios that can be applied to real-life real-worker situations.
- Use the simulator to work through a series of scenarios. Demonstrating degrees of hearing loss under various circumstances helps users better understand how different exposure levels may affect hearing loss.
- Gather and use trainee input to tailor lessons to the end user. Scenarios that participants can directly relate to are more meaningful, relevant, and motivational.
