SafetyMeter software is protected and can only be operated with the SafetyMeter
soundcard, accessories and specied hearing protection products.
3 Installation
The SafetyMeter system provides in-situ verication of the acoustic attenuation provided
by a Phonak hearing protection device.
SafetyMeter conrms the eectiveness of Phonak’s hearing protection systems by
checking that the in-ear shells properly seal the ear canal.
Reasons for leaky hearing protection devices include:
uImproper in-the-ear t of the shells by the user. This can be easily improved by training
the user on how to correctly insert their hearing protection.
uWrong size/shape. Occasionally custom-molded shells are inaccurately produced, for
example as a result of a poor quality ear impression being taken. A shell that fails
SafetyMeter should be sent back for replacement. Ideally a new ear impression should
also be taken.
For more information check section 10 (Background information) of this User Guide.

4 SafetyMeter operating modes
SafetyMeter has 4 operating modes:
uAttenuation control: this is the main operating mode. It serves to verify the protection
level provided to the user by a Phonak hearing protection device, while the user wears it.
The result of an attenuation control is a graph of the attenuation level versus frequency, for
the left and right protections, as well as an estimated Personal Attenuation Rating (PAR).
A Personal attenuation control certicate (in PDF form) is generated when an attenuation
control session has been completed. This certicate summarizes the main information
concerning the particular user, their product and the protection provided. The results are
also stored in an Excel le.
uDemonstration: this mode is used to demonstrate to a customer what a SafetyMeter
attenuation control session involves. It features a sequence of typical session screenshots.
uData browser: this allows the operator to sort attenuation results by company and by
date, then export this data into an Excel le.
uSystem check: performs a 2-step check of the SafetyMeter's headphones and probes
to ensure that the system is fully operational and attenuation control results are accurate.
The SafetyMeter software automatically requests a system check once every 6 months.
System check 1: veries that the sensitivities of the microphones contained in the head-
phones and in the probes are matched. This test requires Check disc 1.
System check 2: veries that the probes are perfectly sealed and do not have any defects that
might adversely aect the results of the attenuation control. This test requires Check disc 2.

* The Personal Attenuation Rating (PAR) is based on the result of a single us er test with SafetyMeter.
The PAR is the “single user equivalent” of a Single Number Rating (SNR) as measured per ISO 4869. The PAR is
computed like an SNR except it is calculated individually for the user and does not include a standard deviation
correction.
The [PAR-1.1dB] is the “single user equivalent” of a Noise Reduction Rati ng (NRR) as measured per ANSI S3.19-1976.
The [PAR-1.1dB] is equal to an NRR calculated individually for the us er, i.e. excluding standard deviation corrections
and 3dB spectral uncertainty factor.
In case of doubt, please use the SNR and NRR attenuation values as given i n the user instructions.

There are several reasons why communication with the update server might not be
established.
10 Background information
SafetyMeter veries the attenuation that a Phonak hearing protection ear shell provides
to the user, while he or she wears it.
There are several advantages to running a SafetyMeter test:
uUser and employer rest assured that the hearing protection is protecting the user
eectively.
uThe user receives training on how to t his/her ear shells and experiences how it feels
when the hearing protection is worn correctly.
uTest results are stored and can be included in hearing conservation programs, helping
employers to comply with national standards and/or the recommendations of
occupational safety organizations.
The SafetyMeter test is objective and does not require the user to provide any subjective
feedback. The soundcard plays reference sounds through the headphones while miniature
microphones, mounted in the probes, capture the residual sounds inside the user's ear
shells. The dierence between the two signals is used to compute the eective attenuation
provided by the shells.
A relatively quiet room (such as an oce) is needed to run a SafetyMeter test. The
attenuation check takes approximately 20 seconds, whereas a complete sequence including
user training, attaching the probes, tting the shells, wearing the headphones and running
the software lasts around 5 minutes per person.
The SafetyMeter software also provides self-test functionality in order to guarantee
that all elements – soundcard, headphones, probes and software – stay operational over
time. A system check with the probes in use is automatically required by the system
every 6 months.

2 Rechtliche Hinweise
Der SafetyMeter ist ein System zur in-situ Verikation der akustischen Dämmwirkung, die
von einem Phonak Gehörschutz System geboten wird.
SafetyMeter bestätigt durch die Verikation die Eektivität (die sachgerechte Abdichtung
des Ohrkanals durch die Ohrschalen) von Phonak Gehörschutzsystemen.
Gründe für schlecht isolierende Gehörschutzsysteme können sein:
uUngenaues Einsetzten (Position im Ohr) der Ohrschalen durch die Benutzer. Dies kann
einfach durch eine Unterweisung "Sachgemäßes Einsetzen des Gehörschutzes" für die
Benutzer verbessert werden.
uFalsche Größe/Form. Persönlich angepasste Ohrschalen können eine falsche Form
aufweisen. Dies passiert, wenn der Ohrabdruck eine schlechte Qualität aufweist. Eine
Ohrschale, die den Test des SafetyMeters nicht besteht, sollte mit der Bitte um Ersatz,
zurückgesendet werden. Idealerweise sollte ein neuer Ohrabdruck genommen werden.
