3M E-A-Rfit - Attenuation Graph; Octave Band Analysis; Detail View; Comprehensive Measurement Data

14
IMPORTANT NOTE
i
Hover your mouse over the Fitting Gauge needle to see how the PAR results compare to others who were tested on the same
model. You may also hover your mouse over Your Fit to see the PAR value.
Attenuation Graph
The Attenuation Graph tab plots the attenuation at each of the seven octave bands for the left ear (blue) and the right ear (red).
The PAR values for left, right, and binaural are values carried over from the Quick View tab. This information allows the
operator to analyze the shape of the curve and look for abnormalities.
IMPORTANT NOTE
i
Low attenuation values in the lower frequencies might indicate a poor seal.
Detail View
In the Detail View Tab Results, the full value of the PARs are displayed for left, right, and binaural along with associated
uncertainty values.
In the middle of the screen, the formula for the protected exposure is displayed and calculated providing the results for the
recommended user protected exposure.
