Model 831 Manual Data Display 9-5
Data Display
The Industrial Hygiene measurement data are displayed on
the
Overall tab of the Data Display View, as are the results
of the basic sound level measurements as described in
Chapter 5 “Data Display” on page 5-1.
Four sections will appear: Sound Exposure , Dosimeter 1,
Dosimeter 2 and SEA. The two dosimeter displays will be
identical except for the measurement values (if they had
been setup with different measurement parameters). These
four sections will be found just before the last section of the
Overall tab.
Sound Exposure
FIGURE 9-5 Overall Tab, Sound Exposure
The Sound Exposure page on the Overall tab shows sound
exposure metrics (in this instance for A-weighted). L
AE
is
the sound exposure level (previously known as SEL). The
Sound Exposure metrics indicate the actual and extrapolated
(8 and 40 hours) exposure accumulated in terms of hours
and seconds. These are discussed in "Sound Exposure (SE)"
on page D-16 and "Sound Exposure Level (SEL, LE)" on
page D-17.
