Noise Measurements Made
The main noise measurements taken by the doseBadge depend on
the settings and the regulations being followed:
- OSHA and related regulations: TWA, Lavg
- ISO 3dB and related regulations: Lep,d, Leq
The doseBadge also measures, calculates and stores other parameters,
such as Dose %, Peak , and Pa2hr, which are needed for some
noise exposure regulations.
The doseBadge has dual channels, and can
have Channel 1 configured to have different exchange (doubling)
rate, time response, threshold, criterion level and criterion
time. Channel 2 is fixed to the common ISO 3dB settings. This
means that you can work to regulations such as OSHA but still
record the ISO parameters too.
The main measurement parameter (Lavg or Leq, depending on
settings) is stored every minute, giving a graph of the sound
level over time when downloaded to a computer. The C Weighted
Peak is also stored every minute for similar graphing.
