New research by SPPUA’s Dietmar Offenhuber explores the interaction between environmental noise and the built environment, an often-neglected area in urban planning and design.
Offenhuber, an associate professor of art, design and public policy, analyzed an exploratory noise sensing project in Los Angeles that investigates qualitative and quantitative aspects of the noisescape.
Using an experimental array of noise sensors mounted on city street lights, the researchers collected noise data that demonstrate the revealing nature of spatially and temporally granular urban sound data.
“By analyzing sounds in various frequency bands at different resolutions, we investigate how aspects of urban design such as landscaping, material choice, and building typologies impact the sonic environment,” the researchers said.
Their study reveals the spatio-temporal geography of low-frequency noise that usually goes undetected using traditional noise sensing methods. Based on these results, they present a model predicting noise based on traffic data.
