Dear All,
I am very new in arduino and i am planning to make a noise detector device using Arduino Uno Please Give some Sugession and help me?

What are the sensitivity, dynamic range, and bandwidth requirements for your detector? Or perhaps what and why you wish to measure 'noise' might help with suggestions.

Here is a recent Instructable that has an audio board  Measures Sound Pressure to connect to an Arduino Board.
Is this what you were looking for?
http://www.instructables.com/id/Sound-Pressure-sensor-for-Arduino-based-on-ZX-soun/ (http://www.instructables.com/id/Sound-Pressure-sensor-for-Arduino-based-on-ZX-soun/)  Not that the Resistor Capacitor circuit creates a high frequency cutoff filter ( which is good to measure sound pressure).

I  just give you some links I googled about a noise detector.

Same circuit on different website.
