摘要： A continuous environmental noise level recording and analysis system is provided. The system is capable of sampling, processing and storing Equivalent Sound Level values over a period of about two weeks. The recorded data is downloaded and analyzed to show graphs, and to automatically detect noise events of interest. The measurement system conforms to ANSI/IEC Type I or Type II standards for noise level monitoring
