Welcome to the Hush City  app!

With this app, you are an active part of a citizen science research project to map quietness in cities.
Our cities have become increasingly noisier by the hour. Only in Europe, over 125 million people are affected by noise pollution from traffic every year, and apparently, quietness is becoming a luxury available only for a few of us. By using this mobile app, you will contribute to making quietness available for all those appreciate it.

This mobile app will help you to identify, access and evaluate “everyday quiet areas” in your neighborhoods. You can find places such as small, quiet spots where you can go to escape the city’s chaos, relax, read a book, play with your kids, and have a pleasant conversation. Chill out!

Join the community. It is simple.

  • Go to one of your favorite quiet spots
  • Record the sound where you are in the quiet spot
  • Take a picture of the spot where you recorded the sound
  • Answer the questionnaire about this quiet spot
  • Share this information with your community.

Or, use the app to find a quiet spot near to you. Go to it and enjoy spending some time there.

* Please be aware that noise levels measured by the mobile app, may not be entirely accurate, depending on which smartphones are used, weather conditions and other factors.
