Always sunny in my mind ,

This app seems to work well. Of course calibration is another matter .. I can easily set the threshold level and it actually responds to my intent well.



Most other “decibel” meters keep constant noise level about 30 dB no mater what and which cannot be reset reduced etc., giving high level noise in a perfectly quiet environment (to my ears of course ;)



Bottom line - high marks to this app, it is simple but at least threshold noise calibration is responsive and it makes sense ...
