HEAR TODAY, HEAR TOMORROW?
The ability to speak and listen to others is fundamental to our participation in work, education, social activities and the community at large. Yet every day, thousands of Australians risk hearing loss and tinnitus through choices we make about exposure to loud sounds in the work-place, at sporting or leisure activities and in the home. Damaged hearing cells
Normal hearing cells
Like sunburn, damage to hearing cells results from the intensity of the sound, duration of exposure and how often you are exposed. This figure shows normal hearing cells and hearing cells damaged by noise exposure (E) in a human cochlea.

UP TO 10% OF YOUNG AUSTRALIANS ARE REGULARLY EXPOSED TO HIGH LEVELS OF LEISURE NOISE FROM THE COMBINED EFFECTS OF NIGHTCLUBS, PUBS, LIVE MUSIC VENUES AND PERSONAL STEREOS (MP3). (From Binge Listening 2010, a report by. The HEARing CRC member, Australian Hearing).

Average noise levels is average LAeq
SOUNDS LOUDER THAN 85dB CAN CAUSE DAMAGE The LAeq takes into account all the varying sound levels experienced at an event and produces a single figure (in decibels).
The HEARing CRC’s mission is to reduce the economic and health impact of hearing loss through more effective prevention and improved remediation of hearing loss. Developed with Intrinsically Safe design and low cost of ownership and replacement in mind, The HEARing CRC’s Safears™ incorporates smart digital sound processing to enable wearers to hear sound and speech at normal loudness while remaining protected in high noise environments.
The HEARing CRC’s research is aimed at developing more effective public awareness of the risks to hearing associated with both work and leisure activities. Hearing loss from noise damage adds up over our lifetime. In just one year, leisure noise exposure for a young Australian can be almost 3.5 times of the allowable workplace noise exposure.

Are You Protected? We can all protect our hearing by using personal hearing protection (earplugs, headphones) and by managing our daily noise exposure – reducing the volume, limiting our listening time and taking breaks from noise.
