Abstract: This thesis explores the relationship between road traffic noise and
sleep patterns, high blood pressure, and annoyance in Somerville, Massachusetts. Road
traffic noise is assessed using a noise propagation model and predicted average day, night,
and 24 hour noise decibel levels are calculated at the homes of participants in an ongoing
NIH study of the health effects of exposure to ... read moretraffic exhausts in the Somerville area
(n=204). Using these modeled noise values, spearman correlations are calculated to assess
the relationship between residents' sleeping patterns, high blood pressure diagnoses, and
overall annoyance to road traffic noise. Modeled noise levels show that residents living
closest to major roadways are subjected to noise levels that are 36% higher than WHO
standards. Correlation results find a significant and positive correlation between the
modeled noise levels and resident annoyance towards road traffic noise.
