We developed land use regression (LUR) models for LA<sub>eq24h<\/sub>, L<sub>night<\/sub>, and L<sub>den<\/sub>\u00a0to assess the long-term spatial variability of environmental noise levels in Montreal, Canada, considering various transportation noise sources (road, rail, and air). To explore the effects of sampling duration, we compared our LA<sub>eq24h<\/sub>\u00a0levels that were computed over at least five complete contiguous days of measurements to shorter sampling periods (20 min and 24 h). LUR models were built with General Additive Models using continuous 2-min noise measurements from 204 sites. Model performance (adjusted R<sup>2<\/sup>) was 0.68, 0.59, and 0.69 for LA<sub>eq24h<\/sub>, L<sub>night<\/sub>, and L<sub>den<\/sub>, respectively. Main predictors of measured noise levels were road-traffic and vegetation variables. Twenty-minute non-rush hour measurements corresponded well with LA<sub>eq24h<\/sub>\u00a0levels computed over 5 days at road-traffic sites (bias: -0.7\u2009dB(A)), but not at rail (-2.1\u2009dB(A)) nor at air (-2.2\u2009dB(A)) sites. Our study provides important insights into the spatial variation of environmental noise levels in a Canadian city. To assess long-term noise levels, sampling strategies should be stratified by noise sources and preferably should include 1 week of measurements at locations exposed to rail and aircraft noise.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Statistical modeling of the spatial variability of environmental noise levels in Montreal, Canada, using noise measurements and land use characteristics.
