영화에서 사운드는 화면상의 표현에 사실감을 부여하거나 과장된 효과를 이용해서 이미지를 부각하는 기본적인 역할을 수행하며, 관객으로 하여금 영화 속 대부분의 소리가 일상적인 것으로 받아들이게 한다. 그러나 영화 속 사운드는 실제 현실에서 접하는 '소리'가 아니라 영화적 재현을 위해 허구적으로 연출된 장치이다. 이러한 기능들로 인해 관객은 스크린을 통해서 허구인 영화의 세계가 마치 현실처럼 느껴지는 독특한 '현실감'을 체험하게 되는 것이다. 따라서 사운드연출은 청각적 요소의 운용을 통한 독창적인 이미지 전달로 이러한 현실재현에 기여해야하며 나아가 다양한 영화적 표현들이 효과적으로 관객에게 전달되기 위해서는, 주관적 청점을 기반으로 한 사운드연출이 우선적으로 고려되어야한다.

A variety of noise control methods have been developed as an interest on noise issues increases. Among them, noise control methods using masking effect, a phenomenon to reduce the ability to notice the unwanted sound by proper sound, to implement a pleasant sound environment have been studied under the name of soundscape. We proposed a novel vector base amplitude panning(VBAP) based noise control method to apply to the building environment. The proposed method could improve the amenity inside the building to reproduce the sounds with excellent masking effect on the incoming path of noise using the control speakers, considering the direction of noise source. The directional masking sounds can be generated by using VBPA technique. To verify the performance of the proposed method, we carried out the subjective test for the degree of amenity according to direction of the masking sound. Subjective test results showed that it is possible to improve the amenity inside the building by controlling the direction of masking sound considering the human's auditory characteristic.

Purpose: To investigate audiometery and characteristics related to tinnitus in tinnitus patients, and to understand the relationship between the discomfort of tinnitus and the quality of life. Methods: The subjects were 110 patients with tinnitus. The data were collected using tinnitus handicap questionnaire, quality of life, and pure tone audiometry, which measured hearing level in dB and frequency in Hz matching of tinnitus. Results: Majority of tinnitus patients (75.5%~81.8%) had normal auditory sensation. but 82.7% of patients indicated that they have heard tinnitus "frequently" or "always", and the major sounds of tinnitus were "wing, wung, wang". The matching sounds of tinnitus had various range in hearing level(dB) and frequency(Hz). Tinnitus patients reported moderate levels of the discomfort of tinnitus and the quality of life, and there were negative correlation between the discomfort of tinnitus and the quality of life(r=-.314, p<.001). Conclusion: These findings suggest that special attention is needed for tinnitus patients because the physical, psychological, and social impacts of tinnitus could be decrease their quality of life. Specialized nursing intervention considering specific conditions related to tinnitus is required to solve various health problems of tinnitus patients.

Vowels are classified by vocal tract shapes. These shapes form constriction points along the tract, which have an influence on such vocal tract resonance as $F_l,\;F_2,\;F_3$, and so on. This study reviews the perturbation theory of the tract and determines the corresponding formant frequencies from modified vocal tracts using vocal tract area function. Then, formant variation is observed from the theory. Finally, each set of $F_l,\;F_2,\;and\;F_3$ frequency is input to a speech synthesis software to make a vowel sound. Auditory impression of each sound without any modification of its vocal tract shape is almost the same as the corresponding phonetic symbol. Formant frequencies of $F_l,\;F_2,\;F_3$ vary according to the perturbation theory. Generally, constriction along the node causes formant values to decrease while constriction along the anti-node cause it to increase. Vocal tracts modified by more than $3\;cm^2$ change vowel qualities of /a/ and /i/ into those of f /v/ and /$\varepsilon$/, respectively. This study will be helpful in simulating sounds from modified vocal tracts before any operation. Further studies are desirable to compare vocal tract shapes of various languages and their sounds together.

Floor impact sounds from two different floor systems were measured. One of the two floor systems is a dry floor system (with 150mm concrete slab) and the other is a standard floor system (210mm concrete slab). Real impact sources such as jumping and running of children were used as well as standard impact sources (bang machine, impact ball and tapping machine) to evaluate sound Isolation of the two floor systems. Subjective evaluations of the floor impact sound isolation performance for the two systems were also conducted by the methods of 3 scales & 9 categories, paired comparison and semantic differentials. Measurement results indicate that floor impact sound isolation performance of the dry floor was better than that of standard floor in both cases of real and standard impact sources. The subjects in auditory experiments also evaluated the dry floor as a better sound isolation system.

제품을 홍보하는 영상 광고에는 다양한 감각 요소가 사용된다. 시각적 요소와 청각적 요소를 활용한 영상 광고는 마케팅의 대표적인 수단이라 할 수 있다. 이와 같은 감각 요소를 활용하여 제품을 홍보하는 광고 영상은 로고 혹은 특정 이미지, 문구 등 시각적 요소를 지속적으로 또는 반복적으로 노출시키며 시청자에게 각인시킨다. 그러한 시각적 이미지는 브랜드 이미지를 효과적으로 심벌화하는데 효과적인 방법으로 사용되고 있다. 대부분의 자동차 브랜드의 광고 영상에서 시각적인 요소를 심벌화하였다면, 기아 자동차 K5의 광고 영상에서는 청각적인 요소 즉 사운드를 심벌화하여 K5만의 차별화된 광고 영상을 제작하였다. 본 논문은 청각적 요소를 심벌화한 기아 자동차의 K5 광고 영상을 타사의 자동차 브랜드 광고 영상과 비교 분석하였으며, 광고 영상 제작에 활용된 기법과 효과를 연구하였다.

Up to now, there have been rare clinical studies on leaders and aerobics athletes. To get the useful data for protecting from auditory disorder, we selected 15 female aerobics leaders (experimental group) and 15 females (control group) unexperienced in aerobics and a without neurological and octolaryngological disorder. The average age was $34.87{\pm}8.80$ (experimental group) and $34.07{\pm}8.45$ (control group) years, and the average career of an aerobics leader (experimental group) was $8.33{\pm}4.73$ years. We measured the auditory evoked potential (AEP) of the two groups treated with 70, 75 and 85 dB intensity from January 2006 to May 2006 and analyzed the absolute latency (AL) and interpeak latency (IPL) by the SPSS/pc+ 12.0 program. In the comparison of the AL between the experimental group and the control group according to intensity, both ears treated with 70 and 75 dB had a significant difference (p<0.05) in the I, III, V wave and in the I, V wave respectively, and the experimental group treated with 85 dB showed a difference in the I, III, V wave (left ear) and in the I wave (right ear) respectively. The IPL of the two groups treated with various intensities had no prolongation. In the comparison of the AL between the experimental group and the control group according to ages, the experimental group in their 20s treated with 70 dB showed a significant difference (p<0.05) in the V wave (left ear) and in the I, III, V wave (right ear), and the experimental group in their 20s treated with 75 dB in the I, III wave (left ear) and in I, III, V wave (right ear), and experimental group in their 20s treated with 85 dB in the V wave (left ear) and in the III, V wave (right ear). The experimental group in their 30s treated with 70 dB had a significant difference (p<0.05) only in the V wave (right ear). Only in the IPL of subjects in their 20s treated with 85 dB, III-V and I-V of both ears was extended. In the comparison of the AL and IPL according to career, there was no significant difference between the two groups. From this results, we concluded that the lower sound intensity (70 dB) showed a more significant difference in the experimental group than the control group. We concluded that the leader of aerobics exposed to louder sounds than normal people are affected by auditory neurological and octolaryngological disorders. So we think that the leaders of aerobics need to control the noise level for protecting themselves against a disease.

In contemporary modern society, people are constantly exposed to many kinds of noise, such as that from machinery, aircraft, construction sites, or road traffic. Noise is considered one of the most indispensable and influential parts of human life. This study investigates the acoustic characteristics of noise transfer from external sources to the human ear. For this study, we measured and analyzed various types of noise environments, installed monitoring speakers in a semi-anechoic room, and conducted intentional noise-filled experiments. In this environment, the size of the sounds generated by use of a portable device was also measured and the SNR (signal to noise ratio) calculated to study the influence of the noise. As sound is transmitted to the ear and the human body, it affects not only auditory damage but also other parts of the body. In this paper, we propose a proper SNR for noise emitted by portable IT equipment to prevent hearing loss when IT equipment is used.

When consumer evaluates a product, every aspec of the product affects the evaluation. Human uses at least five sensory organs for the evaluation. Multi-sensory or multi-modal design tries to add auditory and olfactory factors to the traditional visual-centered design. For the multi-modal design, it is essential to understand relationships between combined sensory stimuli and human sensibility. Information between simple sensory stimulus and human sensibility is pre-requisite to combine multi-modal stimuli. This study investigated human sensibility against 8 colors and 30 sounds, presented independently. The combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli was investigated with 20 female subjects. For combined stimuli that generated the same kind of sensibility respectively, generated sensibility was same but strength was diminished. For combined stimuli that generated the different sensibilities respectively, subjects showed neutral sensibility or no special sensibilities. Sensibilities to the same stimuli also showed difference depending on personal background of the subjects.

This presentation aims to explore some possibility of non-segmental phonetics usually ignored in phonetics education. In pedagogical phonetics, especially ESL/EFL oriented phonetics speech sounds tend to be classified in two criteria 1) 'pronunciation' which deals with segments and 2) 'prosody' or 'suprasegmentals', a criterion that deals with non-segmental elements such as stress and intonation. However, speech involves more dynamic processing. It is non-linear and multi-dimensional in spite of the linear sequence of symbols in phonetic/phonological transcriptions. No word is without pitch or voice quality apart from segmental characteristics whether it is spoken in isolation or cut out from continuous speech. This simply tells the dichotomy of pronunciation and prosody is merely a useful convention. There exists some room to consider dynamic non-segmental phonetics. Examples of non-segmental phonetic investigation, some of the analyses conducted within the frame of Firthian Prosodic Analysis, especially of the relation between vowel variants and foot types, are examined and we see what kind of auditory phonetic training is required to understand impressionistic transcriptions which lie behind the non-segmental phonetics.
