What You'll Learn
Use the NYC311 Service Request data
The NYC311 Service Request system provides support to people in New York City by collecting requests for various governmental services, including filing noise complaints. Each observation contains 53 variables that describe detailed information about each service request, such as the complaint type, date received, incident location, and description of the complaint.
The NYC311 database contains over 4 million noise complaints, which can be used to quantify census tract-level socioeconomic disparities in noise complaints. This data can be used to create linear mixed-effects models, estimating monthly tract-level noise complaints based on factors such as the proportion of low-income residents, time in months since January 2010, and potential confounds like total population and population density.
By analyzing noise complaint patterns, we can identify trends such as higher noise complaint rates in areas near street intersections, during weekends, and in the late evening. Additionally, noise complaints about outdoor noise sources tend to increase during warmer months.
To map noise pollution by borough, you can download base maps of each borough and divide the raw data accordingly. For example, Manhattan and Queens have noise pollution distributed across almost the entire borough, while Brooklyn, Staten Island, and the Bronx have noise pollution concentrated in the northern and southern areas, respectively.
Visualizing noise pollution data can be done using the 'stat_density2d' function from the ggplot2 package, which performs 2D kernel density estimation. This allows for a more comprehensive understanding of noise pollution patterns across New York City.

Visualise noise pollution with the 'stat_density2d' function
To gather evidence of noise pollution in NYC, one can refer to the city's noise complaint repositories, which contain over 4 million municipal noise complaints. These complaints can be accessed through the NYC311 database, which allows residents to file noise complaints and provides support by collecting requests for governmental services. The data includes detailed information such as the complaint type, date received, incident location, and description of the complaint. Analyzing these complaints can help identify neighbourhood-level noise conditions and associated annoyance, especially in areas near street intersections, during weekends, and in the late evening.
Another way to gather evidence is through the deployment of acoustic sensor nodes, such as the Sounds of New York City (SONYC) project. This project utilizes over 55 low-cost sensor nodes to monitor urban noise continuously, accurately, and in real-time. The data collected by these sensors enables large-scale analysis, predictive noise impact models, and interactive 3D visualizations to identify patterns across space and time.
Additionally, consumer smartphone technology has enabled crowdsourcing of in situ sound pressure level (SPL) measurements through citizen science-led noise mapping projects, referred to as participatory sensing. While this approach allows for data collection from diverse locations, it has limitations in spatial-temporal coverage and accuracy due to variations in microphone sensitivity and device conditions.
To visualize noise pollution in New York City using the stat_density2d function, one can refer to the following code snippet:
R
Mp1 <- ggmap(manhMap) + stat_density2d(aes(x=lon, y=lat, fill='red', alpha=..level.., size=0), data=inmanh, geom = 'polygon') + facet_wrap(~ Borough) + theme(axis.ticks = element_blank(), axis.text.x = element_blank(), axis.text.y = element_blank(), legend.position = 'none') + xlab("") + ylab""
Mp2 <- ggmap(brooMap) + stat_density2d(aes(x=lon, y=lat, fill='red', alpha=..level.., size=0), data=inbroo, geom = 'polygon') + facet_wrap(~ Borough) + theme(axis.ticks = element_blank(), axis.text.x = element_blank(), axis.text.y = element_blank(), legend.position = 'none') + xlab("") + ylab""
Mp3 <- ggmap(bronMap) + stat_density2d(aes(x=lon, y=lat, fill='red', alpha=..level.., size=0), data=inbron, geom = 'polygon') + facet_wrap(~ Borough) + theme(axis.ticks = element_blank(), axis.text.x = element_blank(), axis.text.y = element_blank(), legend.position = 'none') + xlab("") + ylab""
Grid.arrange(mp1, mp2, mp3, ncol = 2)
In the above code, the stat_density2d function is used to visualize the spatial distribution of noise pollution in Manhattan, Brooklyn, and the Bronx, respectively. The function takes the longitude (lon) and latitude (lat) as input and visualizes the density of noise complaints using a red fill color. The alpha and size parameters control the transparency and size of the plotted points, respectively. The facet_wrap function is used to create a separate plot for each borough, and the theme function customizes the plot by removing axis ticks, labels, and legends. Finally, the grid.arrange function is used to arrange the plots for each borough in a grid with two columns.
By utilizing the stat_density2d function, the visualization provides insights into the density and distribution of noise pollution across different areas of New York City, aiding in the understanding and mitigation of noise pollution in the city.
