이 연구는 도시공간의 어메니티를 실현하기 위한 수단으로서 사운드스케이프(soundscape)에 관한 연구조사의 결과를 소개한다. 사운드스케이프 및 사운드스케이프 디자인에 관한 개념과 사상을 고찰하고, 남원시의 사운드스케이프 조사를 예로 하여 지역에 있어서 음, 인간 및 환경과의 관계로부터 사운드 어메니티(sound amenity)를 실현하는데 있어서 음이 갖는 의미와 역할을 모색한다. 사운드스케이프 조사방법으로써 문헌조사, 필드조사 및 설문조사를 이용하여 남원지역의 음풍경을 조사${\cdot}$분석하고, 그 시대적, 계절적, 시간적인 음풍경의 변화와 현상, 그리고 지역주민의 음에 관한 인식특성을 파악한다. 조사결과, 지역에 있어서 자연환경을 보존하고 축제등의 전통적인 생활문화를 계승하는 것은 지역의 사운드스케이프와 어메니티 형성에 중요한 역할을 한다는 점을 알 수 있었다. 또한 도시공간의 사운드스케이프 연구는 이러한 일련의 조사연구활동 및 교육활동 등을 포함한 다양한 활동과 여러 영역에서의 유기적인 교류활동이 이루어져야 쾌적한 음환경 창조가 가능하다는 점을 확인할 수 있었다.

For the comfortable housing life, comfortable and pleasant urban environment should be created for the people living in house and in city. There are lots of environmental conditions in city affecting house and life. Also most of all the noise pollution have been become major factor that makes people's life uncomfortable. Recently soundscape researches have been performed to create comfortable urban environment and various studies on the evaluation of urban environmental sounds are now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out alternative evaluation method for urban environmental sounds. Adjectives applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time. As a result, new physical parameters such as Lmax, Unbiased Annoyance, G, N and EmT have a feasibility to evaluation of urban environment sounds in terms of acoustic comfort.

For the comfortable housing life, an urban environment should give comfort and pleasantness to people living in house and in city. There are lots of environmental conditions in city affecting house and life and most of all the noise pollution have been become factor that makes people's life hard without need to say. Recently researches have been performed to create comfortable urban environment and a study on the evaluation of urban environmental sounds is now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out evaluation method for urban environmental sounds. Vocabularies applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time.

This study performed an physical analysis on the characteristics of urban environmental sound divided into three parts depending on their features. Object sounds were classified into traffic sound, waster sound and spatial sound. Traffice sound was selected because it is dominant sound in urban environment, and water sound is selected because it generally supplies pleasantness in contrast to traffic sound, Finally spatial sound was considered because it represents sound in various places of city having lots of behaviors and types of sound due to them. Physcal analysis was carried out using sound quality indices based on Zwicker's loudness, $L_{Aeq}$(equivalent noise level), Ln(percentile noise level) and other acoutical attributes applied to previous study. Through the analysis, this study aims to compare the acoustical characteristics of urban environmental sound and to provide fundamental data for the evaluation of urban environmental sound.

Currently, there are various sounds in the urban surrounding environment such as natural, human, mechanical or sound, etc., and these urban environmental sounds remain in several memories according to magnitude, repetition, learning and experience of sounds. However, there are limitations in memorizing these environmental sounds, thus they are forgotten or reminded, or replaced with new ones from time to time. This study was attempted to look into the changes of the memory of noisiness annoyance and sharpness of the suggested sound sources with urban environmental sounds as time goes by and the order of memorization of the sound sources.

기후변화로 인한 도시열환경 악화, 온열질환자 발생은 중요한 사회 문제 중 하나로 대두되었다. 이에 폭염 등의 기후변화에 관한 연구가 활발해졌으나 주로 기후요소에 집중되고 있다. 그러나 도시열섬현상은 여름철 폭염을 가속화시키며, 도시지역에서의 온열질환자가 급증하는 추세로 미루어 도시의 환경의 영향을 짐작할 수 있다. 이에 본 연구는 서울시와 경기도를 대상으로 도시지역의 물리적·사회적 특성이 온열질환자에 미치는 영향을 분석하였다. 분석을 위해 본 연구에서는 음이항회귀분석을 활용하였다. 분석 결과, 토지이용현황 중 주요열에너지방출원인 주거·상업·공업시설 연면적의 비율은 통계적으로 유의하지 않은 것으로 나타났지만, 도로면적과 녹지면적은 각각 양과 음의 영향을 미치는 것으로 나타났다. 사회적 특성 변수에 포함된 인구밀도와 65세 이상 인구 비율, 독거노인 비율, 기초생활수급자 비율은 모두 유의한 것으로 나타났는데, 독거노인 비율과 인구밀도 비율만 음의 영향을 미치는 것으로 나타났다. 연구의 결과는 지역별 온열질환자와 관련한 도시 정책적 대안을 마련하는데 활용할 수 있다.

The assessment of an urban site depends on the way it responds to multiple needs such as functionality, aesthetic and complex comfort of acoustic, thermal, lighting and air quality This study aims to investigate the assessment of various urban soundscapes in the sense of acoustic amenity by the questionnaires. As a result, acoustic amenity assessment was influenced by the non-acoustic factors such as environment assessment of visual, thermal, air quality etc.. And it was shown that the subjects tend to perceive the noise level less than 3$\sim$10dB L$_{Aeq}$ under the similar noise exposure level according to the urban landscapes.

The assessment of an urban site depends on the way whether it responds to multiple needs such as functionality, aesthetic and complex comfort of acoustic, thermal, lighting and air quality etc. This study aims to investigate the assessment of various urban soundscapes in the sense of acoustic amenity by the questionnaires. As a result, acoustic amenity assessment was influenced by the non-acoustic factors such as environment assessment of visual, thermal, air quality etc. In the sense of sound quality, urban environmental sound was interpreted as 3 factors of strength, evolution of time, spacial localization. So these factors would be considered in the new assessment method for acoustic amenity. And it was shown that the subjects tend to perceive the noise level less than $3{\sim}5dB\;L_{eqA}$ according to the urban landscapes under the similar noise exposure level.

도시 유동인구가 증가함에 따라 도시 환경 소음에 관한 연구의 중요성이 증가하고 있다. 본 연구에서는 교통상황에서 발생하는 이상 소음을 최근 환경 소음 분류 연구에서 높은 성능을 보이는 딥러닝 알고리즘을 이용하여 분류한다. 구체적으로는 타이어 제동 마찰음, 자동차 충돌음, 자동차 경적음, 정상 소음 네 개의 클래스에 대하여 합성곱 신경망을 이용하여 분류한다. 또한, 실제 교통 상황에서의 환경잡음에 강인한 분류 성능을 갖기 위해 빗소리, 바람 소리, 군중 소리의 세 가지 환경잡음을 설정하였고 이를 활용하여 분류 모델을 설계하였으며 3 dB SNR(Signal to Noise Ratio) 조건에서 88 % 이상의 분류 성능을 가진다. 제시한 교통 소음에 대하여 기존 선행연구 대비 높은 분류 성능을 보이고, 빗소리, 바람 소리, 군중 소리의 세 가지 환경잡음에 강인한 교통 소음 분류 모델을 제안한다.
