HEARING LOSSHearing loss, caused by exposure to noise at work, continues to be a significant occupational illness despite the improvements made for comfort and attenuation. Hearing protection can play a vital part in avoiding occupational hearing loss. Comfort and ease of use play a role as economical, practical noise protection that conforms to the local legislation is the priority. Hearing loss can be gradual because of exposure to noise over time, but damage can be caused suddenly by extremely loud noises. The damage is disabling as it can stop people being able to understand speech, keep up with conversations or it may develop into tinnitus (ringing, whistling, buzzing or humming in the ears), a distressing condition which can lead to disturbed sleep.

EXPOSURE & PROTECTIONHere is a rule of thumb, If you must shout to be understood over the background noise when standing about 1 meter away from somebody, that background noise is hazardous. using EN352 Hearing protectors - Safety requirements and testing these problems can be easily prevented.Protection is required if the noise is over 85dB. Below 75dB is non-hazardous.Noise regulations define exposure action values in lower and upper values. The amount of time exposed to the noise hazard also determines the level of protection required.

Improved protection can be obtained by wearing a combination of earplugs and earmuffs. In general the most useful combination is a high performance earplug with a moderate performance earmuff. In practice the increase in attenuation expected from dual protection will be no more than 6dB over the better of the protectors.

DECIBEL dB

If the noise hazard is 108 dB and the hearing protector is SNR24 then the result

108-24=84 dB then the below 85dB regulation is achieved.

CONFORMITYManufactured to EN 352-1:1993 – ear muffs as per the requirements of Council Directive 89/686/EEC “personal protective equipment”, article 10, EC type examination.

PACKAGING & STORAGEPacked 15 each per carton.

SPECIAL INSTRUCTIONSProtection will only be offered if the earmuff is fitted correctly. Earmuffs may deteriorate with use and should be examined at frequent intervals.

Do not apply paint, solvents, adhesives or self‐adhesive labels, except in accord-ance with instructions from the manufacturer.

Before selection of a suitable ear defender a noise survey should be carried out. Hearing protection should be used in accordance with the European Physical Agents (Noise) Directive 2003/10/EC. The user must read and familiarize themselves with the correct uses of the prod-uct as directed on the packaging.

EN 458, a European guidance document that gives hearing protector recom-mendations, suggests selecting hearing protection devises that reduce the level of exposure to the ear to between 70 and 85 decibels A‐weighted sound level (dBA).

If a protector with too high an SNR attenuates noise to below 70 dBA, the wearer also is overprotected and is at risk of missing key alarms and instructions.
