如何使用麦克风在Android应用程序中以分贝记录声音强度？

Question

I need to measure ambient noise on my android application. Let's say I allow the microphone to be turned on briefly, say 30 seconds. I would like to have a decibel value in return that is representative of the sound intensity.

I do not want to record any sound. I want to simply calculate the intensity of the noise captured through the microphone for 30 seconds and turn the microphone off.

PS I am newbie and clueless. I'd need step by step sample code.
