UCi SNR 35 Optime III

Based on new technology, the UCi SNR 35 Optime III features double casing that minimises resonance in the holder casing. The Optime III therefore provides high-frequency muffling, whilst allowing the wearer to understand speech and signals. The Optime III is available in a standard headband version, or as a neckband version, enabling it to be worn with other protective equipment such as helmets.

The Optime III is available in 2 versions:

• Standard headband (available as single or 20 pack)
• Neckband version (available as single or 10 pack)

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.)
