Noise pollution is a major problem in many communities. Big industry, military operations, and airports are all capable of producing damaging levels of sound. Wilderness areas need to monitor noise to protect wildlife. Because this type of pollution has a high impact on the safety and quality of life, this E-Team from Dartmouth College developed, by request from Lebanon Municipal Airport, an efficient, low-cost, and portable noise-monitoring system.
The system is a robust, weatherproof, and portable package backed up with solar power for use anywhere. It employs digital and analog technology, and is equipped with long and short-term data storage, user-friendly hardware and software controls, and data analysis software. The system automatically monitors low-complexity noise and records its findings.
