I need a decible meter for my N7.

I have a 2013 automobile that is driving me nuts. There is a lot of wind noise around the windshield.
I am going to tape up around the windshield, then fronts of doors and windows  etc. so I can isolate the problem before I take it to the dealer. It would be good if I can show them the amount of wind noise I hear.
Yes, I did have my hearing thoroughly tested recently, they could not find anything wrong and would not sell me anything to mask the noise.
Can anyone recommend a sound (decibel) meter app that works with the N7?

Smart Tools Co.  has a free Sound Meter app that should work with the N7. I paid for the full Smart Tools app, and its Sound function works with my old and new version N7s.
