I never see below 30dB values although the room would be quiet.
The linear scale is usually 0, while, say, typing on keyboard can give 8 (on linear).

The db scale usually gives 30. It could be related to atmosphere pressure or something, but I don't understand how.

The loudest noise is getting the stylus into N900 quickly: 106 on dB scale, 200 on linear.

Looks like math artifact, linear is fine. It's probably due to input scale limitation.

I'm loving this app.

Is there a way to measure more than 106 db??

Can you add dBa ? It's more common for sound measure.
(you have to add a filter witch reduce the bass)

Why i can't find dBa on Wikipedia, and why WolphramAlpha doesn't know what it is?
