Did what I needed. It never seems to go below 30-35 decibels, but then I read somewhere online that the library is between 30-40 decibels, so it seems to be working great. A minor downside is that the instructions say it may need to be recalibrated at some point in the future, but there don't seem to be any instructions on how to do that.
