Building noise maps is always accompanied with a lot of human efforts and time costs.This paper designs and implements a system based on participatory sensing.The mobile part and the server part are two key components in this system.Smart phones in mobile part measure the noise level around them.Noise data is uploaded to the server part after calibration.The server part collects these data,recovers the loosed data and builds the noise map.Users can query the noise map according to their demands.Experimental results show that the error of the calibration is less than3 dB and this system builds the real-time and fine-grand noise map with low overhand.
