Keywords a week: noise

The name of this work is "Noisy City". The author Karim Douïeb is the data scientist of Brussels and the co -founder of Jetpack.ai. The work creates a set of maps that show noise pollution in the three cities of Paris, London and New York. These maps can not only visualize the sound level, but also perform acoustic processing (scan the original QR code at the bottom of this section to read the original text. Feel the acoustic treatment of the work).

In the exchange with Nightingle's Claire Santoro, Karim Douïeb talked about the original intention of making this work. According to the World Health Organization, noise pollution is one of the biggest threats facing European environmental health. According to the European Environment Agency estimation, only 48,000 new heart disease cases and 12,000 premature death cases are made every year in Europe alone. Karim Dou 表示eb said: "Many people are surprised by these facts, so I ask myself how to make more people realize this health problem?"

Compared with static noise reports, the author's mapping data in visual and sound uses sounds to explain the noise, and the sensory experience makes the noise data more formal. The author believes that the reason why this work can achieve surprise is the following three points:

Interactive visual effects are usually more attractive than static images.

Using different intensity urban sounds make the experience simple and clear, readers directly understand that we are talking about noise.

This experience is personalized. You explore the city, find your neighbors or where you have been there, and realize how noisy they are compared to other parts of the city.

In the interview, Karim Dou eb shared the tools used to complete this work: noise from a cycle MP3 of various cities recording; using QGIS (a free open source geographic information system software) to edit, style, and unified noise charts; Then use MAPBOX to provide these maps to the application, which also allows readers to interact with the map and provide street name coverage; as for the web application, it is built using the JavaScript framework React.
