* The Personal Attenuation Rating (PAR) is based on the result of a single user 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 Rating (NRR) as measured per ANSI S3.19-1976.
The [PAR-1.1dB] is equal to an NRR calculated individually for the user, 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 in the user instructions.
