Abstract
This study presents the development and preliminary evaluation of a wireless acoustic sensor network (WASN) designed for environmental noise monitoring in Thailand. A WASN prototype was developed and deployed at a construction site in Bangkok. The system's performance was evaluated over 240 days, comparing its measurements to a certified Class 1 sound level meter. Preliminary results indicated that the WASN tended to report lower 1 minute A-weighted equivalent continuous sound level values than the Class 1 sound level meter with an average difference of 8 dB. The study also identified key challenges during field deployment, including downtime caused by power loss and Wi-Fi connectivity issues. Future work will focus on addressing these limitations to improve system reliability and measurement accuracy.
