Where there are all the flowers, the songs of all kinds of insects and birds are put in, the sunshine and shadows flicker The forest through which the water sound flows is an optimum resting space. All living creatures in these spaces will awaken the five senses of humans and perhaps turn the sensibility index (EQ). The forest meditation in the forest, which can be an optimal shelter for the people who need it, needs to feel the reverence of nature, to refine emotions, to be a self-reflection, to have a mind to respect, Have an important meaning. In this paper, we tried to consider the cause of the influence of forest sounds on human hearing from the acoustical aspect. The type of sound source of forest was divided into four seasons of spring, summer, autumn, winter. And the change in the duration of the sound during the four seasons, so that the general characteristics of the sounds of the four seasons are as follows: It can be seen that the change in the ratio of sub-band energy is almost equal to the change in dB in frequency of the equal-light curve. To compare this phenomenon, the criterion for changing the sound duration of each forest is natural The main forms of the luminance curve, such as the change in the duration of the white signal in the sound, are determined by the minimum, maximum audible frequency and the most sensitive frequency band, and the auditory characteristics of the other three inflection points Determines the overall shape of the equal-light curve.

Absorptive material arrangement method for effective interior noise control is proposed. Sound field with arbitrary boundary condition is formulated by Kirchhoff-Helmholtz integral equation. A simple example such as a rectangular cavity will present physical meaning between changing boundary condition and control of sound field. The effect of changing boundary condition is expressed in modal admittance. From this formulation. an admittance map is presented. The admittance map is the figure to represent position where absorptive material is attached for effective interior noise control. The admittance map can be assigned to each resonant frequency. There. however, may be common area of those maps. Then, frequency robust arrangement of absorptive material in noise control will be presented.

쾌적한 음환경을 창조하기 위해서는 무엇보다도 음이 갖는 심리적 속성과 인지구조 를 파악하는 것이 중요하다. 이 연구는 여러 가지 환경음중에서 유쾌음에 대한 심리적 속성, 그리고 그 속성과 음과의 관계를 정성적으로 파악하는데 목적을 두고 있다. 특히, 음에 대한 감정 및 정서표현에 사회문화적 차이가 있다는 점을 감안하여 한국어 표현어를 심층적으로 조사·분석하고, 36종류의 표현어와 34종류의 유쾌음에 대해서 평정척도법을 이용한 심리평 가 실험을 실시하였다. 실험의 분석결과, 유쾌음의 심리적 속성은 활동성, 안정성, 박력성의 3가지 요인이 중요한 요인으로 밝혀졌다. 또한, 음과 표현어사이의 관계를 파악하기 위해 다 차원척도법을 이용한 선호도분석에 의해서 3가지 요인과 음과의 관계를 파악해 보았다. 이 결과는 유쾌음에 대한 평가시 중요한 심리적 속성으로서, 음의 물리적 평가방법 및 음환경 의 쾌적성 창조를 위한 중요한 실마리를 제공해 줄 수 있을 것이다.

This paper deals with the nature and function of intensification in Korean in a wider scope of context which was not paid proper attention. Unobserved new areas of intensification are paid more attention like sound split of polysemy e.g. [s'eda], [kyongk'i] by n of intensification and north Korean application of intensification on [wonsu] and intensification of borrowed English. The recent phenomenon of 'gwua' intensification is experimented on two groups of people, young students and old people beyond 65 years old by means of sociolinguistic analysis. The result shows that its intensification is a form of student violent power and a mark of extreme solidarity among activist students. In conclusion, the nature of so called saisiot[t] e.g. intensification is voiceless tensed pause and its functions are the polarization of the original meaning of the word, sound split of polysemy and attachment of social values by intensification.

This paper aims to confirm the mispronunciation of native Korean students due to the phonetic and phonological system differences between English and Korean, and to find the works-to-do by experiment. Many Korean students tend to differentiate the sounds of word-final stop consonants not by vowel duration or the allophones but by the phoneme of the consonant itself. In English, Stop sounds change through the conditions of the aspirated, unaspirated, or unreleased sounds. But in Korean they are not allophones of phonemes but distinct phonemes. Therefore, many Korean students are apt to add an extra vowel sound /i/ after the final stop consonant in the eve form due to both the unperception of the differences between the phonemes and the allophones of stop consonants, and the influence of the Korean sound-sequence relationship. Since the replacement of the allophones and extra vowel addition does not change the meaning, the importance was almost lost. Nevertheless, this kind of study is essential for the precise learning and the use of the English language.

Water is the origin of all things and has been standing as a symbol of eternity which neglectes birth and death, or time and space. We mankind , however, confronts the water pollution or moreover the situation threatening even our existence as the results of considering it as mere consumables without any study on its original meaning or nature. Now, we should search for the way to understand the substance of water and to use it in the course of nature, getting rid of the altitude of merely consuming it. Our traditional way of life is in harmony with the nature and water has been adopted in the space as the important element of the nature especially as per the theory of geomancy. Man can be inspired by the plasticity , motion, sound , and reflectivity of water adopted and harmonized in the space, and the concept such as water both of inner and outer space or hierachy of a microcosmis to be composed by the natural order which lines up a man-water-space.

The purpose of this article is to discuss that ajaeng sanjo music playing (ASMP) can change a person's life. Ajaeng is often called a Korean cello and is the largest and lowest-pitched instrument in the string instrument family in Korean music. From far away it has a deep, low sound. Its low sound adds to its comfort and peace. Listening to a low tone music can help you calm down and heart-easing. As soon as he listened ajaeng sanjo music he felt that low sound is mildly under his patronage. He felt much more interesting energy and vitality about our minds and bodies are in ajaeng sanjo music. He could immerse himself in playing ajaeng sanjo music (ASMP) for several years. The Korean music, tune is one of expression, meaning it is inseparable from the feeling. Many studies show that low tone music not only activates brain power, but soothes minds. Music always stood by him during difficult times. In a word, ASMP leads him to change of life and music is the language of emotion to him.

The possibility of global noise reduction by the sound power control through selection of distribution and impedance of absorptive materials is discussed. It is necessary to investigate the relation between the global sound energy in the field and the total sound power radiated by sources. In the previous work,$^{(1.2)}$ the authors presented a useful design method to change boundary condition that can be useful to reduce noise in acoustically small enclosures. Changing boundary condition Is related to not only enclosure’s geometrical shape but also acoustical treatment on walls for example, attaching of impedance patches (ex: absorptive material). In many practical situations, we often meet situation to change acoustical treatment on walls. The possibility of total acoustic potential energy(globa1 noise) reduction by acoustic source power control is examined in an acoustically small cavity Using acoustic energy balance equation, the relation between global noise control performance and absorptive material’s arrangement/impedance is deduced. Numerical simulation is performed to interpret its physical meaning in terms of absorbent’s distribution and impedance.
