title = "Soundscape engineering of a promenade on Namsan Mountain Park by noise, sound, and preference maps",
abstract = "Namsan Mountain is a 262m-high mountain located in the center of Seoul. It functions as a park rather than a mountain and has a 7.5km-long promenade around it with a moderate slope. Some sections of the promenade are accompanied by trees and rills, which provide a good sonic environment, but the other sections are influenced acoustically by shuttle buses, road-traffic and various noise sources. Noise map for the road-traffic was generated to find the spatial distribution of the noise over the mountain including the promenade. It shows that the promenade of Namsan Mountain is exposed to the noise levels ranging from 55dB(A) to 75dB(A). The natural sound which was identified most frequently by visitors was rill sound and rill-sound map was generated. Individual responses from 4 acousticians and 6 non-acoustic people were collected from on-site questionnaire about sonic environment along the promenade at 37 evaluating spots. The results of questionnaire were used to generate preference map. Separate and combined analyses of the three maps were performed and the addition of the rill sound was proposed to improve the sonic environment. To determine the levels of the rill sound a listening experiment was conducted and the adjusted levels of rill sound were incorporated into the noise map.",
