4 SafetyMeter operating modes
SafetyMeter has 4 operating modes:
u Attenuation 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 certificate (in PDF form) is generated when an attenuation
control session has been completed. This certificate summarizes the main information
concerning the particular user, their product and the protection provided. The results are
also stored in an Excel file.
u Demonstration: this mode is used to demonstrate to a customer what a SafetyMeter
attenuation control session involves. It features a sequence of typical session screenshots.
u Data browser: this allows the operator to sort attenuation results by company and by
date, then export this data into an Excel file.
u System 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: verifies 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: verifies that the probes are perfectly sealed and do not have any defects that
might adversely affect the results of the attenuation control. This test requires Check disc 2.
