Chapter 2: General safety measures and regulations
Section 2
Individual means of protection
against noise
These individual means of protection
serve to lower the sound energy
transmitted to the ear by air. They are
used when it is not possible to avoid
a damaging exposure in any other
way. They exist in various types and
with varying filtering capacity: helmets,
muffs, plugs (Fig. 2.3).
The helmets and muffs offer a
major decrease, but are bulky and
cumbersome and therefore useful
for exposure to high levels of noise,
but short periods of time (two hours
maximum).
Plugs are generally less annoying
and are useful in case of prolonged
exposure to noise of a lower noise
level.
Whenever the level of personal daily
exposure to noise is equal or superior
to 85 dBA, we advise the use of
appropriate means of individual ear
protection.
