Interactive Tools for Teaching Hearing Loss Prevention
The Hearing Loss Simulator (HLSim) is a Windows® based program that 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.
Play around with the Noise Meter and hear the different sounds and sound intensities of everyday objects. The red bar below shows how long it takes before a particular sound level becomes dangerous to the human ear. For example, a chain saw has a sound intensity of about 110 dB. Without proper hearing protection, running a chain saw for only 2 minutes can become dangerous to the human ear!
EARLAB provides activities, services, and products that support the practice of hearing conservation at NASA field centers. Our educational resources and training tools are also freely available to hearing conservationists, acoustical engineers, and educators worldwide. All EARLAB products are now available as free downloads from the new EARLAB website. These popular educational resources and training tools, formerly distributed by the Glenn Research Center Acoustical Testing Laboratory, include the Auditory Demonstrations Series, interactive training games (such as JeopEARdy), and applications (MACSUG). EARLAB's resources are free and publicly available and have been distributed worldwide to hearing conservationists, acoustical engineers, and educators worldwide since 1997.
This is a collection of games, demonstrations and activities that will answer three important questions:
1. What are the sources of dangerous sounds?
2. What are the effects of listening to dangerous sounds?
3. How do I protect myself from dangerous sounds?
The Virtual Exhibit is based on the Dangerous Decibels exhibit at the Oregon Museum of Science and Industry in Portland, Oregon
A Europe-wide campaign to tackle one of Europe’s most persistent workplace health problems - noise at work. Too many people are exposed to high levels of noise and have to raise their voices to be heard during their working hours, which can lead to deafness, tinnitus and other problems. How noisy is your work environment?
