Abstract
In the present study, the effect of footstep noise on emotions was investigated. This study used noise stimulus of human footsteps throughout the study. First, Korean emotion lexicons were collected from narratives of residents living in multi-family housing buildings. The lexicons were then classified into four emotion clusters, with three expressing negative emotions (anger, dislike, and pain) and the fourth depicting empathy. Since self-reported annoyance has long been investigated as one of the major non-auditory responses to noise, annoyance was measured along with affective responses in a laboratory experiment with varying noise levels. The findings revealed that the emotion and noise annoyance experienced by the participants were significantly affected by noise levels. All clusters expressing negative emotions showed strong correlations with noise annoyance, whereas that representing empathy showed the weakest correlation. Noise sensitivity and attitudes to the noise source were observed as possible moderators in emotional responses and annoyance ratings.
Highlights
Emotion is expressed in various forms such as facial expressions and language [1] and it has been commonly investigated by analysing physical and linguistic expressions
Lexicons expressing emotions induced by neighbours’ footstep noise were collected and emotional responses were assessed in a large sample of participants hearing noises
Participants in the first survey were residents of multi-family housing buildings (n = 133) and they were asked to choose appropriate lexicons expressing their emotions while listening to the noises
Summary
Emotion is expressed in various forms such as facial expressions and language [1] and it has been commonly investigated by analysing physical and linguistic expressions. Subtle emotional feelings cannot be determined through physical analyses [8] because of the influences of psychological or physical activities [9] As another approach, emotion can be studied by examining linguistic expressions. Ortony et al [12] collected a number of lexicons from the literature on emotions and categorised them into eight groups, including physical, affective, and cognitive states. These eight categories were tested by asking people to rate the emotion lexicons; it was found that the most discriminable categories were affective, cognitive, external, and bodily conditions
