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.
