104db@ 10 feet is a bit of a stretch. That's the rated levels of a Federal 55 AC resonating horn, which are fairly accurate. The SpectrAlert Advance is rated around 88db on 16VDC, so around 88-95db is more typical. I can take some readings of my P2RK on both low and hi volume (I'll wait till the neighbors are out for that ) this week.
