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.

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.

The deterioration of the urban heat environment due to climate change and the occurrence of heat-related diseases have emerged as one of the major social problems. This has led to more research on climate change, including heat waves, but it is mainly focused on climate factors. However, the urban heat island phenomenon accelerates the summer heat wave, and the increasing trend of heat-related patients in urban areas suggests the impact of the city's environment. Thus, this study analyzed the effects of physical and social characteristics of urban areas on heat-related patients in Seoul and Gyeonggi-do. The analysis showed that the ratio of the total area of residential, commercial and industrial facilities, the main source of heat energy locality, among the land use statuses, was not statistically significant, but the road area and the green area were found to have a positive and negative The population density and the percentage of people aged 65 or older, the percentage of people living alone and the proportion of people receiving basic living were all shown to be significant, with only the ratio of elderly living alone and the ratio of population density having negative effects. The results of the study can be used to develop urban policy alternatives related to local warming patients.

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.

As urban population increases, research on urban environmental noise is getting more attention. In this study, we classify the abnormal noise occurring in traffic situation by using a deep learning algorithm which shows high performance in recent environmental noise classification studies. Specifically, we classify the four classes of tire skidding sounds, car crash sounds, car horn sounds, and normal sounds using convolutional neural networks. In addition, we add three environmental noises, including rain, wind and crowd noises, to our training data so that the classification model is more robust in real traffic situation with environmental noises. Experimental results show that the proposed traffic sound classification model achieves better performance than the existing algorithms, particularly under harsh conditions with environmental noises.
