1 LOSS OF HEARING: UNLIKE EYE, HEAD AND RESPIRATORY INJURIES, HEARING DAMAGE IS NOT NECESSARILY PAINFUL OR VISIBLE AT THE TIME OF OCCURRENCE. HOWEVER, NOISE SHOULD BE REGARDED AS A PHYSICAL HAZARD. THE RESULT OF PROLONGED EXPOSURE TO EXCESSIVE NOISE CAN RESULT IN PHYSICAL CUMULATIVE INJURY - LOSS OF HEARING. Acoustic waves are a fundamental part of your hearing ability - which cuts both ways. The waves are a prerequisite for the transmission of sound but if they are not within the ear s natural acoustic range, they have a destructive effect. Located inside your inner ear are the wave specialists: hair cells with their fine hairs. It is these hairs that are set in motion by the sound waves the ear receives. And the higher the sound level, the more the hairs flutter. This motion is converted into nerve impulses that are passed on to the brain. But if the hairs are repeatedly subjected to excessively high doses of sound, they eventually break off. Those that survive only manage to transfer a fraction of the information. The result is impaired hearing.

Ear Muff Covers Ear Muff Belt Clip Ear Muff Hygiene Kits Ear Plug Storage Box INDICATION OF SOUND LEVELS 1db Aeroplane 110db Bulldozer 10db Pneumatic Drill 80db Voice (screaming) 60db Voice (speaking) 0db Listening to soft music in home 0db Sound of a breeze in the trees db Minimum level of noise perceived ATTENUATION TABLES TYPES OF PROTECTION AVAILABLE Ear Muffs are a traditional form of ear protection providing a wide level of protection. Since they are very visible they make it easier to enforce the wearing of protection in the workplace. Ear Muffs can be supplied with a number of options such as helmet mounting and built in radios. Ear Plugs are convenient and comfortable to wear and can provide a higher level of protection than ear muffs. Plugs can also be provided banded or corded for convenience when not in use. For each product an Attenuation Table is provided which details the noise reduction tested at frequencies between 6Hz and 8000hz. The tables provide figures for the Mean Attenuation, Deviation for the test and the Assumed Protection. The Assumed Protection is the Mean Attenuation less the Deviation. These tables allow the user to select the product which suits the application taking into account the background noise levels and frequencies. IDENTIFY THE HAZARDS To identify the risk a Noise Survey should be carried out. The survey will identify the background noise levels and frequency range and can be used as the basis of selecting the most appropriate products. 9
