Zone 3 Hearing Range

The Zone 3 Hearing Range is suitable for environments with extremely high noise levels.

The Zone 3 Hearing Range is available in 3 versions:

1. Zone Headband Ear Defenders - SNR 34

The Zone Headband Ear Defenders offer the perfect balance between comfort and protection. The optimised headband clamping force and stable twin stirrup ear cup attachment ensures an even and comfortable pressure with consistant attenuation performance throughout the products lifetime. The lightweight and adjustable Headband Ear Defenders fits a large range of head sizes and a foam lining on the underside of the headband ensure endless comfort.

      2.   Zone Helmet Mounted Ear Defenders - SNR 32

The Zone Helmet Mounted Ear Defenders are ideal for situation where both head and hearing protection is necessary, such as construction, forestry, oil & gas and heavy industry. The Helmet Mounted Ear Defenders can easily be converted into a head, face and hearing protection combination utilising the universal 30mm attachment post fitted as standard. Standby and parked positions allow for the product to stand off the head, ready for use, or to park the ear defender out of the way on the rear of the helmet when not in use.

      3.   Zone Neckband Ear Defenders - SNR 33

The Zone Neckbamd Ear Defenders off the ideal solution where safety helmets do not have attachment slots ot hearing protection needs to be used in conjunction with a head mounted face shield or a baseball style bump camp. The Neckband Ear Defenders offer the user the option to balance the weight on the neck rather than on the head, which is the personal preference of some wearers.

Exact colour and style may vary slightly.

A Basic Guide to Hearing Protection:

Hearing protection should ideally limit exposure to between 70 - 80 dB at the ear, and not exceed 87bB. However, it is also important to not over protect as the wearer may not be able to hear other sounds such as fire alarms or vehicles. The wearer can also feel isolated resulting in reluctance to wear the protection when necessary.

dB (decibel) is the unit used to measure sounds intensity. Sounds intensity roughly doubles for every 3dB increase.

SNR is the ‘Simplified Noise Level Reduction’ or ‘Single Number Rating’, which is the simplest way of getting a general indication for the level of protection provided.

The most accurate way to decide whether hearing protection is needed is to arrange a specialist survey from an independent professional.

Simple Equation:

Noise Level                      100dB

Hearing Protection SNR    - 30dB               (This calculation is only a rough guide and does not take into account different frequencies so may no be a suitable measurement.)
