• Abstract:
  This project involved the development of a cost-effective sensor for long-range wireless, autonomous traffic noise monitoring. The device is called the Smart Sensor For Autonomous noise Monitoring (SSAM). The SSAM system developed under this project includes ten prototype sensors that measure and report noise levels periodically (e.g., once per minute) to a prototype base station that may be located up to 1.2 miles away. The data reported by SSAM includes flat-weighted and A-weighted sound pressure levels as well as octave band measurements over the frequency range of 22 to 5657 Hz. The system performance is similar to a Type 1 microphone as demonstrated in laboratory calibration tests reported here. The SSAM system developed in this project has been used to measure highway noise barrier insertion loss. The low-cost design of SSAM as well as the ability to perform autonomous measurements provides a new cost-effective approach to noise monitoring.
