Abstract : Environmental epidemiological studies commonly quantify subjects- noise exposure level in their neighborhood. How this neighborhood is defined can vary across studies, leading to different approaches whose impacts on exposure levels remain unclear. This article examines the impact of the neighborhood-s definition on environmental noise exposure estimates. L Aeq,24h exposures in the vicinity of 10,825 residential buildings were estimated using a high-definition noise map, built on a middle-sized French city. Various definitions of neighborhood address point, façade, buffers, and official zoning were used to produce different exposure estimates. Influence of urban environmental factors was analyzed using multilevel modeling. The results showed a significant increase of the exposure estimates +3.9 dB and a significant decrease of the variability, when the sample size of the considered neighborhood increased P
