현대 사회에서는 세계 인구의 대부분이 도시에 몰려 있기 때문에, 도심의 소리는 중요한 의미를 가진다. 그 중 교통음은 가장 대표적인 도심소리 중에 하나이다. 일반적으로 도심 교통음은 환경소음으로, 대표적인 자연의 소리인 숲, 폭포소리등은 사람에게 긍정적인 효과를 주는 소리로 분류한다. 본 연구에서는 자연의 소리가 포함하는 백색잡음에 다양한 형태의 FFT보정 필터를 적용시켜, 사람이 가장 선호하는 형태의 백색잡음 주파수 특성을 발견하고 자연 소리와의 상관관계를 확인하였다. 그리고 여러 형태의 도심 교통음과 숲소리의 파형, 스펙트럼 비교를 통한 분석을 진행하였다. 분석 결과 도심 교통음이 숲소리에 비해 특정 주파수대역과 시점에 집중된 소리 에너지 특징이 있음을 발견하였으며, 이러한 특징이 사람에게 미칠 수 있는 부정적인 요소들을 확인하였다. 마지막으로 전극법 뇌파 실험을 통하여, 도심 교통음과 자연의 숲, 폭포소리를 직접 피실험자들에게 들려주어, 알파파와 베타파의 에너지 분포를 측정하였다. 측정결과 도심 교통음은 자연의 소리보다 현저하게 많은 양의 베타파를 발생 시켰으며, 반대로 자연의 소리는 많은 양의 알파파를 발생 시켰다. 이러한 결과를 통해 도심 교통음이 사람에게 미치는 부정적인 영향과 자연 소리의 긍정적인 영향을 직접적으로 확인하였다.

The hearing mechanism is a complicated system. Sound is generated by a source that sends out air pressure or power. The pressure or power makes the sound waves. These waves reach the eardrum, or tympanic membrane, which vibrates at a rate and magnitude proportional to the nature of the sound waves. The tympanic membrane transforms this vibration into the mechanical energy in the middle ear, which in turn converts it to the hydraulic energy in the fluid of the inner ear. The hydraulic energy stimulates the sensory cells of the inner ear which send neuroelectrical impulses to the central auditory nervous system. The passive perception of auditory information starts just here. The listener gives attention to the speech sound, differentiates the sound from background noise, and integrates his experience with similar sounds. The listener then puts all of these aspects of audition into the context of the moment to identify the nature of sound. This has a major role in human communication. This paper provides an overview of the nature and characteristics of sound, the structure and function of the auditory system, and the way in which sound is processed by the auditory system.

This research aims to derive the general emotion and preference of the 25 sounds by using the questionnaire method to provide the contents for the soundscape design fit to the characteristics of the given situation. The results can be summarized as follows : Nature sounds except dog barking and locust crying showed highest preference, and the traffic sounds, baby crying and footstep of upper floor showed the lowest. Hereby, the sound recognition can be different each other according to quality of tone and situation even they are the same sounds. The most impressive, wanted to be conserved and retrospective sound was the nature sound, and the most wanted to be removed sound was the machinery sound. And the social sound was shown as the most korean and fit to the art theme street.

There is a unique method of musical expression in the nature documentary. The expression method is Mickey Mousing technique, which expresses the movement of animals with music. The Mickey mousing technique can also be used in other types of documentaries, but it is most prominently used in nature documentaries. The Mickey Mousing technique cannot be used in any field other than music composition, because the composer should describe the movement of animals by playing music to match the animal's movements exactly. It is also because they have to play the instrument separately according to the sound source. In this study, we examined the nature documentaries broadcast by KBS over the last five years and analyzed the cases of Mickey Mousing technique. Therefore, we obtained research results that the Mickey Mousing technique is necessary and that the music composition is also necessary as a background music of nature documentaries.

The laws of physics that govern actions of all moving bodies apply to sound. Because sound and all acoustic conditions consistently behave as described by the law of physics, we are able to predict and analyze the nature of a sound and its interaction. A fundamental understanding of the nature of the sound and terms used to describe it is essential to comprehend the language of otolaryngologists, audiologists, music acousticians, and engineers. Moreover, studying the basic physics of the sound helps one recognize complexities and potential pitfalls in measuring describing sound. We will talk about the structure of sound and its components, and we will see the various qualities of sound that make it interesting and useful to understand.

A common treatment for tinnitus rehabilitation is to use a device called a sound generator to continuously supplying the sound stimuli. The devices usually provides a sound called white noise, or pink noise, which are common in nature. In this paper, we developed a mobile system for tinnitus diagnostics and therapy using Android mobile applications. The first step for tinnitus diagnostics is detecting an exact tinnitus frequency of the patients, therefore we provide a bark scale tinnitus detection algorithm for fast and accurate diagnostics. Also, the system can provide various stimuli sounds including white noise, pink noise, brown noise, nature sounds, and binaural beats. Also we provides the therapeutic functions through questionnaires to solve existing problems of the patients.

This study aims to evaluate factors of floor structure influencing to the floor impact sound. For this reasons, we measured the vibration of floor and the floor impact sound in moment flame structure. The main results from this study are that slab area and thickness are critical factors of the floor impact sound and aspect ratio slab is not verified in flor impact sound.

As the discourse on Anthropocene grows, this exploratory research investigates the interrelationship and interconnectivity between humanity and technology by analyzing a sound art installation created by the author. Crying Sea is a sound installation that uses plastic wastes collected from the shore to create symbolic narratives and artistic experience connecting humans, objects, and nature through interactive digital technology. In this installation, the audiences are guided to walk over the wastes, and the sounds created by the footsteps are recorded in real-time, which then are distorted and amplified into disturbing sounds through speakers filling up the room. In analyzing this artwork, three theories from technological, philosophical, and ecological backgrounds were used; specifically, Bernard Stiegler's pharmakon theory, Dona Haraway's cyborg manifesto, and Timothy Morton's dark ecology theory. A common factor revealed from all three theories by analyzing the Crying Sea is that humans, technologies, and all other entities within nature are interconnected and resonated. The awareness of this recursive relationship allows us to consider sustainable balancing.

Objectives : The purpose of this study is to analyze the various methods of sound therapy(ST) applied to tinnitus patients and their effectiveness, and to suggest an effective method that can be applied in clinical settings. Methods : Studies published from January 2018 to March 2023 were searched on 5 databases(Pubmed, RISS, OASIS, KISS, KCI). All RCTs that applied sound therapy as a main treatment method were included. Results : 14 studies were included. In 13 studies, sound therapy was statistically significant in improving tinnitus. Basic sound therapy was used in 6 studies(42%), followed by tinnitus rehabilitation therapy(TRT)(n=5, 35%). White noise(n=11, 75%) and nature sound(n=4, 28%) were the most frequently used sound sources. In the case of intensity, mixing point were the most common with 6 studies(42%). The mobile application(n=4) was the most frequently used implement. The application time of sound therapy per day was more than 3 hours(n=7), and the total treatment period was more than 3 months(n=9). Conclusions : Our findings indicate that sound therapy could be considered as an intervention for tinnitus patients. For better use, we suggest a basic type of sound therapy or TRT using white noise or nature sound at the mixing point level provided as a mobile phone application. In addition, the treatment period is recommended to be more than 3 hours/day for 3 months.
