Outline of Final Research Achievements

Dental drilling sounds give discomfort and fear for patients in dental offices. Dental drill sound measures are an important task for patients to be comfortably. Typical dental drills operate by compressed air. In this study, the purpose was capturing the acoustical phenomenon of dental drills by numeric fluid acoustic simulation using fluid acoustic engineering. Aerodynamic noise simulation inside the dental drill, which rotates very fast, was calculated by a supercomputer. Furthermore, the simulation result was confirmed a high -precision result compared to the data obtained by actually operating and measuring the dental drill.
