Abstract

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.

성인남성이 면도를 하는 것은 생활 필수요건 중에 하나이다. 생리적인 이유로 대부분의 성인 남성들은 수염을 기르고 있으며, 남성들이 수염을 다듬고 잘 관리하면 외모가 더 깔끔해 진다. 습식면도기에 무딘 날을 사용하거나, 적절한 마사지를 사용하지 않으면 피부 자극이 발생하여 면도상처를 입을 수도 있다. 따라서 면도 후 피부가 매끄러워지는 것만큼 면도기의 편리함과 편안함이 필요하다. 본 논문에서는 습식면도가 피부에 주는 자극을 줄이고, 면도의 편리함을 높이기 위한 소리마사지의 사전 면도방법을 제안하였다. 비대면 저주파스피커를 통해 피부를 부드럽게 하거나 유분을 분비해 피부 윤기를 높여서 면도를 부드럽고 안전하게 해 준다. 우리는 습식면도 전후의 피부상태를 파악하기 위해 습식면도 상태의 소리를 각각 녹음하였고, 이 소리스펙트럼으로 그 효과를 객관적으로 비교분석하였다. 즉, 실험결과에서 면도 전 소리마사지가 면도칼과 피부, 피부와 수염 사이의 마찰이 -7.0dB 감소되어 습식면도의 피부상처를 개선하고, 상쾌한 면도가 이루어짐을 알 수 있다.
