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.
1 Welcome
2 Legal disclaimer
Use the SafetyMeter software only after reading and accepting the license agreement. The
system requirements and SafetyMeter test specications need to be strictly followed.

3 Installation
When the installation is complete, the following shortcuts will appear on your PC’s
desktop:
PDF Folder Contains PDF versions (grouped by company) of all attenuation
control certicates.
DATA Folder Contains the raw data (grouped by company) of all attenuation
control tests. This data can be retrieved and exported to Excel in ’Data
browser’ mode.
The folder ’MONTHLY_REPORTS’ will group all attenuation control
results (independently of the company) in one data le per month
and per operator.
HELP Folder Contains all on-line help topics in a single document that can be
printed and used alongside this User manual. This help document is
available in English, French and German.
SafetyMeter icon Double-click this icon to start SafetyMeter.
3.4 Installing the SafetyMeter equipment
You need a desktop or laptop PC that is capable of playing audio. An attached printer is
also recommended for printing out SafetyMeter certicates, as is Adobe Acrobat Reader
for previewing the PDF certicates.
3 Installation
3.3 Installing the SafetyMeter software
Insert the SafetyMeter CD-ROM in your PC's CD-ROM drive.
The CD-ROM will auto play.
In case of auto play not starting, go to "My Computer", double-click the "CD/DVD" drive
icon, then double-click on the "SafetyMeter.exe" installation le.
Click "Next" and follow the on-screen prompts to complete the installation.
Installation of the SafetyMeter software will only begin after you have read and
accepted the SafetyMeter license agreement.

uIn the
"Playback"
menu, select
the Phonak
PAC Speakers.
uIn the
"Recording"
menu, select
the Phonak
PAC Line.
uConnect the headphone cable to the HEADSET socket of the soundcard.
Check that the cable is properly attached to the headphones' cups: the blue
connector must be plugged into the cup with the L mark. The red connector must
be plugged into the R cup.
Select the probe you are going to use rst. Plug it into the PROBE socket of the soundcard.
The software will issue a warning message if the headphones and probe have been
wrongly connected to the soundcard.
uUsing the USB cable provided, connect the SafetyMeter soundcard to a free USB slot
on your computer.
We recommend always using the same USB slot of the PC if possible, so that you
are not requested to install the soundcard driver again.
Windows Vista and Windows 7 users must manually set the Phonak soundcard as the
default sound device in Windows settings.
uIn the Start menu of
your PC, select "Control
Panel" then "Sound"
settings.

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.

6.2 Operator screen
The operator screen must only be initialized once. Data is stored and reloaded the next
time the software is activated.
6.3 Company screen
'Company name' refers to the company or professional that purchased the hearing
protection in question. All attenuation results and PDF certicates will be stored in a
folder labeled using this name.
'Language for printing' applies only to the Personal Attenuation Control Certicate and
can dier from the screen language (selected under Parameters/Language).
6.4 Product screen
Select the product to be tested from the drop-down list.
If a product is not on the list, check that its corresponding probe is selected and
has passed the System Check.
6.5 Calibration screen
The probes in use must be calibrated daily. We strongly recommend calibrating these
probes on-site just before use.
Make sure the probe and headphones are connected to the soundcard.
Place the probes in the corresponding openings of Check disc 1 as
explained in the on-line help. When Check disc 1 is correctly positioned,
the probes will sit as shown on the right:

The noise reduction level – in dB – of each ear shell is provided for information t.
The Personal Attenuation Rating (PAR) is a single number rating that approximates the
SNR or NRR attenuation values as measured per ISO 4869 or per ANSI S3.19-1974 u.
The PAR expresses the amount of noise reduction – combined for both ears – which the
device under test provides to its user.

6.6 User screen
The 'DWOM Nr.' is a unique identier that links a hearing protection device to a specic user.
The DWOM is printed on the user-label of each device, in both barcode and text form.
We recommend acquiring the 'DWOM Nr' using a barcode reader in order to avoid mistakes.
You can also enter this number manually (it is the 10-digit number below the barcode).
6.7 Measurement screen
Click the blue-tagged probe into the user’s left ear shell.
Click the red-tagged probe into the user’s right ear shell.
User inserts ear shells with the probes attached.
Verify that the shells are correctly positioned in the user’s ear and that the probes are
clicked in.
Place the headphones over the user's ears. If ear-jewelry interferes with the headphones,
kindly ask the user to remove it.
Instruct the user to remain quiet (no speaking or chewing) during the measuring
process.
"Click to start measuring’ initiates the attenuation control process.
The 'Measurement and results' screen shows:
