What are PROTECThear?
PROTECThear inserts are custom-moulded soft silicone earpieces,
individually crafted under the strictest conditions from an
exact impression of the user’s ears.
Comfort
Each pair are custom-manufactured using specially formulated
medical-grade silicone, to offer the highest degree of comfort
whilst providing a highly effective acoustic barrier.
The Filter
PROTECThear ear plugs are vented and incorporate a passive
acoustic filter, which attenuates loud noises whilst maintaining the
ability of the individual to hear speech, ambient noise and to
use telephones and radios.
Excessive background noise is reduced, resulting in
increased safety and working comfort.

Technical
Noise Braker®
It is an axiom of physics that we cannot create or destroy energy.
We can however, convert it. The Noise Braker Filterconverts sonic
energy into thermal energy by means of compression acceleration.
The rise in temperature is so minute you will never notice it. You can still hear
but a dangerous level of sound can not possibly get through the filter.
No sounds over 80dB will pass through the filter.
