Levels of Noise In decibels (dB) according to the American Academy of audiology, from 20 dB to 120 dB between the division, for example, 60 dB is "Normal conversation ".

The littlest sound makes it jump to well over 100db, and a room with no noise is at 80db.

Good app, however mostly useless unless you have a calibrated decibel meter to calibrate it against. I was hoping there were some common device presets or something that would allow a reasonable starting point for a calibrated reading. Without this, the fact remains, you need a decibel meter to calibrate, so may as well use that to measure rather than this app.

The feature to record video is perfect for capturing my upstairs neighbor. Having the time, date and location definitely helps for reporting purposes. Big issue is that the screen goes to sleep early while video recording and stops the recording upon waking up the phone. The settings don't seem to apply to the pic/vid function. Please add options for time and date format as not everyone uses military time. I would change "History" to "Saved Recordings"
