Hearing Protection

As noise induced hearing loss cannot be cured or restored

it must be prevented from happening. It is important that all

protection provided is to AS/NZS 1270:2002.

Personal hearing protection is usually available in two forms:

earplugs and earmuffs.

Earplugs are usually made of silicone or foam and are

inserted into the ear canal. Plugs are best for people who work

all day in noise and who have to wear other personal protection

equipment such as hard hats, masks or goggles.

Earmuffs completely enclose the ear and are held in place

against the side of the head by a headband. They are designed

to block the sound waves from reaching the inner ear, this

process is called attenuation. The higher the attenuation the

more noise is blocked from reaching the inner ear. As not all

ears are the same it is important to choose a hearing protection

solution that suits the working environment, the comfort of

the worker and promotes user acceptance and wearablility.

Earmuffs are easier to put on and remove so are more suited

to people who are exposed to noise intermittently.

Under AS/NZS 1270:2002, the class system is a simple way

to select a hearing protector appropriate to a noise exposure.

Once the extent of the noise hazard has been established the

correct hearing protection can be applied by using a table

such as that below.
