Thank you for using Decibels. This version fixes a bug that in some cases prevented the microphone from being activated when the app was reopened.
Ratings and Reviews
Logarithm
I think everyone miss a point here; the decibel scale is logarithmic. It means (if I remember correctly from my school days) that if a decibel value is twice another one, the actual sound is ten times higher.
Boat skipper
The app is, as far as I can tell,7 quite accurat on db-levels. A bit larger digits on the dial and this is all I need! Thank you!
Way too sensitive!
The ambient noise (a couple of computers in the other end of the room puts it at 50dB. My current typing on the keyboard with the phone 20 cm away peaks at 65 dB. Speaking normal voice into the mic (like you'd do if recording a memo) gives 80dB.
Only good for indicating variations in noise level, but the scale is all wrong.
