coming to the United States soon. According to its developers, the Ambiciti mobile app “measures levels of air and noise pollution street by street in real-time and offers the healthiest route for urban citizens to move and live in their cities.” The app does this by combining “all sources of information available: numerical simulations, observations of fixed sensors, mobile sensor observations and qualitative observation,” so that people can choose a path around the city that minimizes their exposure to noise or air pollution. The developers hope that the information the app provides influences policy decisions and encourages healthier lives.
When the White Noise app first went live in 2008, it went from being one of the first mobile apps to go live in the Apple store to the number one app in the fitness and health category. Eight years later and the White Noise app remains popular and now allows users to upload sounds from around the world. White Noise 7 is ad-supported, so no cost to download.
