“…Since noise annoyance is a subjective indicator, it is affected not only by the level of noise exposure, but also by other mediators, including fear of danger from the noise source [7,8], noise preventability [7], attitude towards the noisy situation [9], and noise sensitivity [7,8,9,10]. Among these mediators, noise sensitivity is defined as “a factor involving underlying attitudes towards noise in general” and is also known to affect noise annoyance; many studies have suggested considering noise sensitivity together when analysing noise annoyance [2,11,12,13,14,15,16]. Few studies have thus far been conducted on noise annoyance in South Korea that consider noise sensitivity and noise level simultaneously, and there have been few investigating a large-scale population.…”
