The E-A-RCaps™ semi-aural earplugs are ideal for
moderate noise exposure levels, and are suited for a
wide range of industrial workplace, particularly for
intermittent noise exposure. Examples of typical
applications include:
� Automotive
� Chemical & pharmaceutical manufacture
� Construction
� Inspection work
� Light engineering
� Metal processing
� Textile manufacture
� Woodworking
The E-A-RCaps™ semi-aural earplugs are tested and
CE approved against the European Standard EN352-
2:1993. These products meet the Basic Safety
Requirements as laid out in Annex II of the European
Community Directive 89/686/EEC and have been
examined at the design stage by INSPEC International
Limited, 56 Leslie Hough Way, Salford, Greater
Manchester M6 6AJ, UK (Notified Body number 0194).
The E-A-RCaps™ semi-aural earplugs are designed to
seal the entrance point of the ear canal to help reduce
exposure to hazardous levels of noise and loud sound.
These products are designed to be worn under-the-chin
and behind-the-neck mode.
Key
APVf (dB) = Mf – sf (dB)
Mf = Mean attenuation value
sf = Standard deviation
APVf = Assumed Protection Value
H = High-frequency attenuation value (predicted noise level reduction for noise with L(C) –
L(A) = -2dB)
M = Medium-frequency attenuation value (predicted noise level reduction for noise with L
(C) – L(A) = +2dB)
L = Low-frequency attenuation value (predicted noise level reduction for noise with L(C) – L
(A) = +10dB)
SNR = Single Number Rating (the value that is subtracted from the measured C-weighted
sound pressure level, L(C) in order to estimate the effective A-weighted sound pressure
level inside the ear).
