Hush City: the app to discover, map & evaluate quiet spots around you! This app will help you find quiet areas in your city and worldwide where you can escape the city chaos, relax, play with your kids, read a book, have peaceful conversations. Enjoy slowing down! Join the Hush City community. It is simple. • Download Hush City app • Go to one of your favourite 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. With this app, you are an active part of worldwide research 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 has become a luxury available only for a few of us. With Hush City, quietness is available for all those who appreciate it. You can learn more about the research project at www.opensourcesoundscapes.org: where citizen science meets soundscape research. * 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 Credits The first version of the Hush City app was released in April 2017 within the framework of the project: “Beyond the Noise: Open Source Soundscapes” (2016-2018).

You can register but the app is buggy, hasn’t been updated, no longer shows a map, the list goes on. ### 1/5 — Ist die App inaktiv? *2025-06-25, version 1.1.3* Leider erscheint alles in weiß. Ich kann absolut nichts erkennen, geschweige denn lesen. ### 1/5 — Hier geht gar nix *2022-08-12, version 1.1.3* Registrierung und Anmeldung Katastrophe, weil keine Buchstaben in den Feldern angezeigt werden. Man tippt quasi blind. Wenn man das geschafft hat, sieht man eine leere Seite, wo eine Karte sein sollte. Nichts funktioniert, auch Menüpunkte werden leer angezeigt. Ist einfach für gar nichts gut die App. Sehr schade. ### 1/5 — Schrift nicht lesbar *2021-11-15, version 1.1.3* Hellgraue Schrift auf weißem Hintergrund. Keine Ahnung was da steht. Und ohne Registrierung geht gar nichts. Dann halt nicht 🤷🏼‍♂️ ### 1/5 — No labels when registering? *2021-08-31* There’s three fields you have to fill in to register, but no labels. Is it a username? An email? A name? A password? Who knows! How this got past Apple review I’ll never understand. ### 5/5 — Macht was sie soll *2021-08-29, version 1.1.3* Ich habe nicht diese Probleme der andere Menschen, die hier bewertet haben. Bei mir funktioniert alles gut und ich finde die Idee und Umsetzung klasse 👌🏼 ### 1/5 — Funktioniert nicht *2021-01-02, version 1.1.3* Die App zeigt nicht mal die Karte an. Das wäre halt das Mindeste. So eine Qualität lässt die Techn. Uni Berlin nicht gerade strahlen. ### 2/5 — Crashes frequently *2019-11-04* Interesting tool that I would love to use more. Has difficulty loading the mic when I want to record and when it does load, the app crashes 9 out of 10 times. Battery draining I can deal with but don’t have to worry about that since the app nearly always crashes. So disappointing! I really wanted to map the sounds around me! ### 1/5 — Interested but why should i register... *2019-09-21, version 1.1.1* Simply no go. I want to test, but i will not register! ### 4/5 — Account required? *2019-09-02* I love the idea but it doesn’t seem to be taking off in the US much at all—perhaps making it possible to use without an account would help? ## Frequently asked questions about Hush City ### What is Hush City?
