Removes the guesswork
October 1st 2007 This year's A+A exhibition in
Düsseldorf was the venue for
the launch of E.A.R's
E.A.RFit hearing protection
validation system.
The patented software
enables the user to know
the level of protection
workers are receiving
personally and does not rely
on other people's data.
Each ear canal shape is
different and fitting
techniques can vary; this
can result in different
protection levels. E.A.RFit is
said to take away the
uncertainty and documents
each worker's Personal
Attenuation Rating (PAR) in
minutes. The test can be
performed on a variety of
E.A.R hearing protectors,
including Classic, E.A.Rsoft
and UltraFit models.
The device is an F-MIRE
(field-microphone-in-realear)
test system with dual
element microphone
measuring sound inside and
outside the ear. It only
takes 8sec to obtain data at
seven standard (125 to
8000Hz) frequencies. The
user will know exactly what
level of protection each
worker receives from each
tested protector, removing
all guesswork. PAR results
will be automatically
documented and stored by
the technician. The
information is valuable for
comparison during
subsequent tests and may
qualify as an insurance claim
reference. More articles from 3M UK Plc: |
