The vehicle exterior design is the main parameter of aerodynamic wind noise, but the modification of it is nearly impossible at a proto-type stage. Therefore, it is very important to verify exterior design and estimate the correct wind noise level at the early vehicle design stages. The numerical simulations of aerodynamic wind noises around A-pillar and wiper were developed for specific vehicle exterior designs, but could not be directly used for the discussions with designers because these need complex modeling and simulation process. This study proposes new approach to A-pillar and wiper wind noise estimation at design stage using response surface methodology of modeFRONTIER, of which database is composed of PowerFLOW simulation, PowerCLAY modeling, SEA-Baced (Statistical Energy Analysis-Based) interior noise simulation, and turbulent acoustic power simulation. New design parameters are defined and their contributions are analyzed. A state-of-the-art, easy and reliable CAT (Computer Aided Test) tool for A-pillar and wiper wind noise are acquired from this study, which shows high usefulness in car development.

Shaving for adult men is one of the essential requirements for life. For physiological reasons, most adult men have beards, and if men trim their beards and take good care of them, their appearance becomes cleaner. If a dull blade is used for a wet razor, or if an appropriate massage is not used, skin irritation may occur, resulting in shaving wounds. Therefore, the convenience and comfort of the razor are required as much as the skin becomes smooth after shaving. In this paper, a pre-shaving method of sound massage was proposed to reduce the irritation of wet shaving on the skin and increase the convenience of shaving. It softens the skin or secretes oil through non-face-to-face low-frequency speakers to increase skin gloss, making shaving smooth and safe. We recorded the sound of the wet shave state to determine the skin condition before and after the wet shave, and objectively compared and analyzed the effect with this sound spectrum. In other words, it can be seen from the experimental results that the sound massage before shaving reduces the friction between the razor and the skin and the skin and beard by -7.0 dB, improving the skin wound of the wet shave and achieving a refreshing shave.

The purpose of the present study was to investigate the effects of in-vehicle noise types and levels of intensity on drivers' driving speed estimation. Noise generated from the vehicle engine and musical sound sampled from the Korean pop were employed as the types of in-vehicle noise and their levels of intensity were systematically manipulated. In experiment 1 where the effect of the engine noise levels on speed estimation was observed, drivers showed the tendencies of driving faster than the targets speeds under lower noise intensity condition whereas driving slower under higher noise intensity condition. In experiment 2 where both musical sample and the engine noise were provided, drivers' subjective speed estimation was affected by the engine noise as revealed experiment 1, but not by musical sample. When the data from the both experiments were combined and analyzed, an interacting effect of engine noise levels and music sample levels was found: if the intensity of music sample was enough to overwhelm the engine noise, the drivers drove faster than lower engine noise level condition in the experiment 1. This result indicates that although the music sample is not the direct auditory cue of speed estimation as observed in the experiment 2, intense level of music sample can affect drivers' speed estimation when it is coupled with the lower engine noise level.

판소리는 극적인 어느 한 줄거리의 이야기를 창자와 고수가 같이 하여 소리 아니리 발림 등으로 표현하여 청중을 웃기고 울리는 공연적인 성악곡이다. 판소리의 예술세계에서 가장 깊은 내면세계와 미학적인 접근을 위해서는 음악적 관점에서 접근해야 한다. 하지만 음악적 기록이 전무한 판소리의 음악적 연구는 실제 소리의 채보에 의한 분석 연구가 필요한데 그 첫 장벽인 채보의 방법론적 검토가 없이 이루어진 주관적인 작업은 보편적인 설득력을 얻기에 부족하다. 우리나라의 전통음악은 전승방법이 서양음악과 달라서 음악의 기준이 되는 악보로써 전승되지 않고 구전으로 이어져 왔다. 따라서 채보에 대한 방법론적 연구는 판소리 뿐만 아니라 산조, 민요 가곡 등 구전으로 전통을 이어온 우리나라 전통 음악을 기술하고 분석하기 위해서 가장 먼저 해결해야 할 문제이다.

As the first step in research for sound synthesis of Pyungjong, timbre was analyzed by FFT analysis. There was no significant difference in the pitch of scale between modern Pyungjong and western twelve-tone equal temperament scale. The timbre of Pyunjong chagnes over time. When striking Pyunjong, the noises to be generated across all frequencies will disappear in a short period of time, and a unique partial only is left. Then it disappear from the partial of high frequency components in order, and two partials remain at release time. At this time, the beating is occurring by the frequency of the remaining partial. Pyungjong used in this study is relatively a recently manufactured Pyungjong, and for original sound synthesis of Pyungjong, a study of ancient Pyungjong's timbre should be additionally conducted later.
