The Quiet Coalition just received news that the Hush City app, developed by Dr. Antonella Radicchi, our scientific advisor and Senior Research Associate and HEAD-Genuit Foundation Fellow at the Technical University of Berlin, has been recognised and honored by the World Economic Forum among the “4 clever projects fighting noise pollution around the globe.”

Hush City app is a free citizen science mobile app that helps crowdsourcing quiet areas worldwide.

In the spring 2019, Dr. Radicchi was on a research stay at New York University in New York City, working with other anti-noise advocates there. We were pleased to co-host her stay in America.

Congratulations, Antonella! We firmly believe in crowdsourcing data about quiet areas as a “democratic” as well as scientifically valid method that will start to make the world a quieter place for all.

David Sykes chairs several professional organizations in acoustical science: QCI Healthcare Acoustics Project, ANSI Committee S12-WG44, the Rothschild Foundation Task Force on Acoustics, and the FGI Acoustics Committee. He is lead author of “Sound & Vibration 2.0” (Springer, 2012), a contributor to the NAE’s “Technology for a Quieter America” and the GSA’s “Sound Matters,” and co-founded the Laboratory for Advanced Research in Acoustics at Rensselaer Polytech. A graduate of UC-Berkeley with advanced degrees from Cornell, he is a frequent organizer of professional conferences in the U.S., Europe, Asia and the Middle East.

Searching for quiet in New York City

In his search for quiet in New York City, John Surico, writing for CityLab, turned to Dr. Antonella Radicchi’s Hush City app in an attempt to find a slice of serenity in the din. Surico joined Dr. Radicchi in a soundwalk of lower Manhattan, and discussed her ressearch. She would like to expand “equitable access to natural urban sounds,” noting there is a difference “between the human sounds of urban living…and the mechanical din of development, which hops up the decibel scale quick.”

During Antonella’s stay while conducting research mapping quiet areas in New York City, we met a number of times and were in contact regularly. As a researcher on the adverse effects of loud sounds and noise on our health and someone who has written and appreciated the wonderful sounds of our city, I welcomed my time with Antonella and enjoyed my Soundwalk with her.

Antonella understands well the sounds of our city that make it “New York”, e.g sounds of Times Square, Macy’s parade, and roars of fans at ball parks. But she also wants us to be able to continue to listen to the sounds of birds, the laughter of children playing, the hum of conversation. With her Hush City app, Antonella spent time mapping out the quieter areas of New York City and stressing the need to protect these spaces, especially the many parks in our city which provide us with the requisite quiet and the opportunity to enjoy more natural sounds.

Dr. Arline Bronzaft is a researcher, writer, and consultant on the adverse effects of noise on mental and physical health. She is co-author of “Why Noise Matters,” author of “Listen to the Raindrops” (children’s book illustrated by Steven Parton), and has written extensively about noise in books, encyclopedias, academic journals, and the popular press.  In addition, she is a Professor Emerita of the City University of New York and Board member of GrowNYC.


Want to be a citizen scientist?


Antonella Radicchi is a registered architect with a PhD in Urban Design and a soundscape researcher.  She is currently an IPODI-Marie Curie Fellow working on her post doc project “Beyond the Noise: Open Source Soundscapes” at the Technical University Berlin. As part of her project, she has developed HUSH CITY app, a free mobile app designed to crowdsource data “related to ‘everyday quiet areas.'”

Radicchi is concerned about how cities have become increasing noisier, noting that in Europe “over 125 million people are affected by noise pollution from traffic every year.” “Quietness,”she laments, “is becoming a luxury available only for the elites.” In order to protect and plan quiet areas, Radicchi’s project applies “the soundscape approach, the citizen science paradigm and open source technology, with the ultimate goal of making quietness as a commons.”

Radicchi is currently working on a pilot study in the Reuterkiez, “a Berlin neighborhood affected by environmental injustice and noise pollution,” using crowdsourced data to target “everyday quiet areas” by using the HUSH CITY app, interviews, and group soundwalks. And she is inviting people to be “an active part of a citizen science research project to map and evaluate quietness in cities” by downloading and using the app. The information that is gathered will be use to generate an “Everyday Quiet Areas Atlas,” a “virtual, open, interactive and multi-layered map,” and “a digital report on how to protect existing ‘everyday quiet areas’ and planning new ones.”

Ah, but I don’t live or work in Berlin, you may be thinking. Not a problem, as you don’t have to be in Berlin to participate. You can identify “everyday quiet areas” in your neck of the woods because HUSH CITY app can be used wherever you are.  If you want to join others to identify, preserve, and create quiet spaces in your community, here’s how to do it:

  • Download the Hush City app–it’s free!
  • 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.

You can download HUSH CITY app at the iTunes Store or Google Play. And for those of you who wonder what happens to the data that is collected–and you should for every app you download–Radicchi states that “all data collected will be stored and shared anonymously and in respect of privacy issues.” You can contact Radicchi directly via @firenzesoundmap or @HUSHCITYapp.
