Sometimes it is hard to find quiet places nearby when you want to escape from the hustle and bustle of the city. We came across a mobile app that helps users find quiet areas close by to relax. Hush City, an app introduced during the ASA meeting in Boston earlier this year, helps users find these “everyday quiet areas” on a map of quietness (Figure 1). The app also encourages users to explore quiet spots in their neighbourhoods by allowing them to record sounds and measure sound levels in decibels with the app (Figure 2). Users can answer a questionnaire of feedback on the sound spot (Figure 3). The collected data and feedback are used for the map of quietness. This actively engages the public in sonic environment evaluation and planning.
