HEARING PROTECTION
Hearing Protection
Earplugs
Ear plugs, made from expandable foam
are the traditional way of protection,
provide the best combination of comfort
and protection for most users against
noise. Once in the ear, the foam plug
expands in the ear canal and fits thus for
everyone. Available with or without cord.
Earmuffs
Most earmuffs enclose completely both
ears with a hollow cup and forms an airtight
seal. The cups are internally insulated and
fitted with sound absorbent foam. A soft-
ring shaped cushion provides a firm but
comfortable seal around the ears. Earmuffs
have a headband to hold the cups in place.
There are also earmuffs available, which can
be attached to the safety helmet directly.
General Information
Noise is part of everyday life, but too much noise can cause permanent and disabling hearing damage. This can be hearing
loss that gets worse over time, damage caused by sudden or extremely loud noises. However, there is no need for your
hearing to be damaged by your work. People should wear a hearing protector if the noise or sound level at the workplace
exceeds 85 decibels (dB). Hearing protectors reduce the noise exposure level and the risk of hearing loss.
Condor personal protective equipment offers you a wide range of quality hearing protection gear to meet
or exceed relevant CE safety standards.

NOISE REDUCTION RATINGS (NRR)
The maximum number of decibels (dB) that a hearing protector will reduce the sound level when worn.
SINGLE NUMBER RATING (SNR)
An SNR is a single number rating system determined according to International Standard ISO 4869. The tests are carried out by commercial laboratories that are independent of the
manufacturers. Like NRRs, SNRs are expressed in dB’s and are used as a guide for comparing the potential noise reduction capability of different hearing protection devices.
