Predictors
We predict noise using simple and common-sense features
These are the predictors of the Rumble score, the 0 to 100 ranking the map draws: 90 means louder than 90% of modelled New York streets. See our methodology section for more context on the score.
Expected move in Rumble score, in points
The score is a percentile ranking. By default, the effects refer to a one-standard-deviation shift in a feature. For binary features (0/1), we show the effect of a change from 0 to 1.
Each effect is marked stat sig the 95% interval excludes zero not stat sig the 95% interval includes zero 95% confidence interval no effect
statistically significant pts- More shops and offices nearby
- Closer to an arterial
- Closer to an expressway
- A bigger class of road
- A wider road
- Closer to a main road
- No homes on this block (0/1)
- A weekday, same hour (0/1)
- More 311 honking complaints
- More 311 noise complaints
- Closer to an elevated train
- Closer to a traffic light
- Closer to an intersection

Model Performance
The model strongly predicts real low-frequency noise in a holdout sample.
We split the model prediction into ten equally sized groups, and then evaluate the actual noise for this group. This is done in a hold-out sample that was not used to train this model.

Key Numbers
Some important numbers on things we collect during our walks
Rows come from different sensors, and different walks often measure different outcomes.
Counted across every walk
over {hours} h of {sensor} readings {sessions} of {total} walks carried this sensor- Honks heard
- Minutes of polluted air · PM2.5 over 100 µg/m³
- Minutes over 70 dB(A): Like a vacuum cleaner or a subway train
- Minutes over 85 dB(A): Like a food blender or a jackhammer
- Minutes of heavy fumes:· VOCs over 1,000 ppb
