In view of the current serious environmental noise pollution problem, a kind of noise monitoring system was put forward, which is based on GPRS and virtual instrument technology. The system deal with the noise data for storage and coding through the microcontroller, and regularly send data to the remote monitoring center through GPRS wireless communication mode. In addition, it can store and analyze the noise data by using the labview software. The whole system has high practicability and reliability, and it is low power consumption, so it become an effective means to environmental noise data acquisition and monitoring.
