Abstract

Noise occurred when medical treatment in dental clinic will affect the patients. This study was measured the noise level and frequency in case of medical examination and also has evaluated the degree of indoor noise using the NR-curve, NRN and a distance to conversation between worker and patients using the PSIL. It shows that noise level was 69.3~81.5dB(A) and frequency was very high (more than 4K(Hz)) and analysis by NR-curve showed that it was exceed the noise permit level and distance to conversation was less than 1meter by PSIL. To remedy a fear of noise in patients and provide a conversational satisfaction, it's considered that choosing the low noise-vib. equipment, using the masking effect and set the room to explain. So It is possible to improve their competitiveness.

본 연구는 치과병원에서 진료 시 가동되는 소음이 환자들에게 피해를 줄 것으로 예상되어 진료 시(스케일링, 보존치료, 보철치료, 임플란트)에 소음도와 주파수 특성을 측정하여 NR곡선과 NRN을 이용한 실내소음 수준 및 PSIL을 이용하여 환자와 근무자 사이의 대화거리 분석을 실시하였다. 진료 시 소음레벨dB(A)의 범위는 69.3~81.5dB(A)이고 고주파성분(4K(Hz) 이상)을 나타내고 있으며 NR곡선에 의한 평가 결과 작업장의 소음기준을 훨씬 초과하는 수준이었으며 PSIL에 의한 환자와 치과병원근무자와의 대화가 이루어지는 거리는 1m 이내인 것으로 나타났다. 병원을 방문하는 환자들의 소음공포증을 해소시키고 환자와 근무자 사이의 만족스러운 대화가 가능한 여건 조성을 위하여 저소음 저진동 장비의 선택, ANC기술개발, 마스킹 효과, 흡음재 부착, 별도의 대화공간 확보 등의 다양한 대책을 수립하므로 치과의료 서비스 질 및 치과병원 경쟁력 향상에 도움이 될 것으로 사료된다.
