**Beta Release:**This software has not fully completed NIOSH's rigorous testing but is considered fully functional. Because of the high level of interest from many potential users this beta version is being made available now. Send comments tomining@cdc.gov.
The NIOSH Hearing Loss Simulator is a software training and communication tool for promoting hearing loss prevention and awareness. It allows a user or trainer to demonstrate the effects of noise exposure on hearing without experiencing an actual noise-induced hearing loss.
HLSim displays a "control panel" for playing sounds while adjusting the simulated effects of noise and aging. A simulated individual's age (in years) can be entered along with the years of exposure to noise (in A-weighted decibels). The effects are shown visually on the frequency band control panel and sound level display screen while the user listens to the audio playback.
This version of HLSim has been redeveloped as a progressive web application (PWA) and supports mp3 sound files as well as other popular audio file formats.
**Prerequisites:**
Modern web browser
**Installation instructions:**
This version of HLSIM can be run from any modern web browser directly from the web.
It can also be downloaded to any PC or mobile device for use when an internet connection is not available. Refer to this installation guide for instructions on how to download to your particular device.
Audience: Trainers, workers, and hearing loss professionals
