Exceedance triggers provide a way to monitor for compliance to additional
exposure requirements. For example, if:
• workers should not be exposed to C-weighted peak levels above 140 dB
• workers' exposure to LAS levels greater than 115 dB should be limited
to a certain duration or to a specific number of occurrences
An exceedance occurs when the measured sound level rises above one or more of
the user-defined trigger levels. For the Spartan 730, there are two threshold levels
(SPL 1 and SPL 2), and three peak trigger levels (Peak1, Peak2, and Peak3). The
process of setting these exceedance levels is explained in section 3.2.1.
The Spartan 730 also allows you to customize the Frequency Weighting, Detector,
and Peak Frequency Weighting for these Exceedance Triggers if you choose to do
so. For the example exposure requirements listed above, you would choose C-
weighting for the peak frequency weighting, and choose S (slow) for the
Detector setting. The process for customizing these settings on the meter is
shown in section 3.2.2.
