Scholarly debates on the unique features of transit-oriented developments (TODs) have surged over the last decade. Studies have examined their amenities and disamenities; however, lacking is exploring the relationship between TOD sound levels and buildings. Understanding this relationship has implications for communities and the urban form from environmental pollution aspects. This study explores the implications of sound on TOD buildings in the Dallas-Fort Worth metropolitan area by comparing them with non-TODs, specifically the relationship between buildings and street characteristics, and sound, as well as the potential effects of this relationship on TOD residents. Data include sound pressure levels through TOD buildings and streets compared with non-TOD buildings and streets. Using a two-level hierarchical linear model (HLM) help examine such characteristics at both micro and macro levels. The findings show that buildings located within TODs are exposed to higher sound levels with 1.4 dB(A) difference. The study provides insights into the relationship between sound, environmental pollution, building science, and transportation-featured elements of the built environment.
