As it turns out, the quietest place in our house was in a closet (50 dB) and the loudest was at the ice maker (101 dB!).
Street noise and a toilet flush are both 78 db.
It's wonderful that the library has this for loan submitted by mickplu on July 10, 2017, 10:21am Great for home schooling projects or just fun to explore the quietest and loudest items in the house.

Sound Meter submitted by Varshini on June 24, 2019, 8:11pm This was cool to test out. However, my house is very quiet with me alone in it, so I didn't have much fun.
