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.
