    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.
