Challenge
Which classes of urban noise co-occur in New York, and which are most common overall? Build a picture of the city's soundscape from volunteer tags.
- Where to start
- Load the annotation CSV (tags per 10-second clip). Count class frequencies; then look at which classes appear together in the same clip.
- What to share
- A frequency chart and a simple co-occurrence heatmap of noise classes.
