What the audio suggests
Each loud event is also run through an audio classifier on the monitor. It labels its best guess at the source from a few seconds of sound. Audio is analyzed on the monitor and never saved.
Every loud event: dBA vs. dBC

Loud events per day
Last 14 days, station local time. Older monitor software only recorded events at or above the dBA threshold, so days before a monitor was updated undercount Δ-only events.
Daily peak levels
Highest dBA and dBC each day. Days with no loud events have no point.
