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/ 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. http://www.docstoc.com/docs/91034206/Electronic-Schematic-Circuit-Diag-for-Noise-Detector Same circuit on different website. http://circuitdigital.blogspot.com/2011/06/room-noise-detector.html http://www.eeweb.com/blog/circuit_projects/noise-detector-for-isolated-room
http://www.slideshare.net/bluemath144729/sound-detector-17732105 Good example of OP-AMPs to amplify Audio input from a microphone and to rectify the audio AC into DC for analog voltage measurement by 10 bit ADC input on the UNO board.
