Typical Applications

Ear defenders, or ear protectors, are essential PPE in any environment where loud or continuous noise is a potential problem. Damage to hearing and even hearing loss are potential side effects of work in high-noise environments, and so ear defenders that provide noise-reduction are important to meet health and safety requirements. Ear defenders are typically used in;
• Power stations • Mining operations
• Airports
• Engine rooms
• Printing
• Cement manufacture

These Peltor Optime III passive ear defenders are CE approved to EN 352-1:1993 and offer an SNR (single number rating) of 35 decibels (dB) for protection against extremely high levels of noise.

Features & Benefits

Can these ear defenders be cleaned?

The ear cushions for these hearing protectors can be easily replaced, for hygiene and comfort over a long use life.

Are ear muffs as effective as ear plugs?

For ear protection in high noise environments, ear plugs can offer a more complete level of noise reduction. However, ear muffs have advantages in that they don't have to be fit inside the ear, and so can be more comfortable, economic and hygienic.

Why are ear defenders necessary?

Exceptional value ear defenders maintaining safety in extremely noisy environments
Special low-profile headband design maintains constant pressure to maximise secure hearing protection
Resonance effect minimised due to double-casing technology
Increased space inside cup reduces moisture and heat build-up for added comfort
Ear cushions are soft and wide reducing pressure around the ears for improved wearability
Easy to replace hygiene kit sold separately

Hearing protection is designed to protect the user from extreme noise levels. The padding of the cushion is made from a type of acoustic foam that absorbs the waves to stop them from reaching the eardrum.

Some everyday tasks can damage your hearing and can have a catastrophic effect. So it's important to protect yourself of task/activities such as mowing the lawn.
