Sound Quality Characteristics of the Cicada Singing Noise in Urban Areas

Abstract

The global warming caused the changes of our environment like an increasing tropical night phenomenon in the middle latitude areas. Especially, in Korea, the habitats of tropical Korean blockish cicada have changed from Jeju island located in Southern part of Korea to the whole of Korea because of the increasingly warming weather. The cicadas crying sound have been social problem because the tropical Korean blockish cicadas cry at middle of the night owing to the various outdoor lights. The cicada is positive phototaxis insect. So, the cicada is not cry at night. But if the outdoor light is very bright, then the cicada confuse the night as a day and start to cry. As a result, the cicadas crying noise has caused the resident living in downtown to an unpleasure and sleeplessness. In this research, we have measured three kinds of cicada singing noise at 16 points of urban area(Incheon, Gwangju, Busan, Gyeonggido Anyang). And then we analyzed the sound quality of the three kinds of cicada singing noise using by CADA-X signal process program. And we analyzed the acoustical characteristics by STFT(short time Fourier transform) which is a time-frequency analysis method. The characteristics of the cicada singing noise in terms of the sound quality and the time-frequency variation will be usefull to discover the relations between the human annoyance about the cicada singing noise and the acoustical characteristics.

The dark side of nature experience: Typology, dynamics and implications of negative sensory interactions with nature

“…For example, some insect, frog, bird and mammal species (e.g. cicadas, pigeons, crows, gulls, foxes) can create loud or repetitive noises, especially when in groups and during the breeding season, which can lead to a severe noise nuisance, especially in urban areas (Gu et al, 2012; Kalnicky et al, 2019; Kung et al, 2015; Lyytimäki, 2014; Temby, 2004; Table 2). Of course, there is likely some variation in how the sound of animals is perceived among people, which is likely to be influenced by multiple personal, cultural and social factors (see Section 3).…”
