A study from the World Health Organisation found that long-term exposure to noise may account for 3% of deaths associated with heart disease and stress. Noise is a particular problem in urban areas and is aggravated by the fact that over half of people now reside in cities.

Pollution issues such as poor air or water quality are now monitored by networks of Internet of Things (IoT) sensors. Yet noise pollution remains largely an ignored issue for now.

Sentec partnered with Polysolar Ltd and the University of Warwick to generate a concept IoT noise pollution sensor – Solar Owl: Sound. It is an economical solution which will make our cities “sound smart”. It can provide local governments with real-time actionable noise data. The cost of each Solar Owl: Sound is less than $20, making city-wide installation a viable solution for monitoring the sound pollution.
