Influence of noise sensitivity on annoyance of indoor and outdoor noises in residential buildings
Applied Acoustics, (2011)
Abstract
A survey and a laboratory experiment were conducted to investigate
the influence of noise sensitivity on the annoyance caused by indoor
residential noises and outdoor traffic noise. Results showed that
noise sensitivity significantly influenced the annoyance level caused
by both indoor and outdoor noise, consistent with previous studies
on transportation noise. Annoyance level was significantly correlated
with sensitivity in both the survey (r = 0.42–0.48 and 0.35 for indoor
and outdoor noises, respectively) and the laboratory experiment (r
= 0.25 and 0.14 for indoor and outdoor noises, respectively), in
which noise exposure was controlled at 50 dBA. The correlation coefficient
for indoor noise was higher than that for outdoor noise and was also
higher than the average values (r = 0.3 and 0.22 for uncontrolled
and controlled noise exposures, respectively) calculated using the
results of several previous studies on outdoor transportation noise.
Sensitivity was found to have a greater influence on the percentage
of people who were highly annoyed by the indoor noise than it did
on those affected by the outdoor noise.
