The ER9 and RC13 filters do not fulfil the minimum attenuation requirements according to
the EN 352-2. For daily noise exposure levels L
h
of 87 dB(A) (for the ER 9) and 88 dB(A)
(for the RC13), a residual sound level at the ear of L
h
= 79 dB(A) is reached. If the exposure time
is halved to 4 h, a level at the ear of L
h
= 79 dB(A) is also reached for a noise exposure level
of LAeq
= 90 dB(A).
The hearing protectors are suitable for 8 h use per day in following areas:
The typical noise situations in these areas, the daily noise exposure level at the ear L
h
does
not exceed the value of 85 dB(A). Thus a secure protection is generally assured by ER 9 and
be suitable.
