Admittedly I am not a power user, so I may not be taking max advantage of the few config settings there are, but I found this useful every time I needed it. One example being testing the noise level of various prospective dehumidifiers. All in all, cool app.

Although I don't often need to measure the noise level around me, this app performs nicely when I do need an accurate measure.
