Application Simulation of Active Noise Control in Dental Treatment
Abstract: This paper introduces the application of active noise control technology, and analyzes the funda-mental of it. The paper points out that it is necessary to use a feedback control system when the original noise information can’t be reached. Since designing an adaptive feedback system can meet this requirement, the paper focuses on the FXLMS algorithm. Compared with traditional LMS algo-rithm, FXLMS algorithm can compensate the second channel in the dental device such as electro-motor driven dental drill or air turbine driven drill, which LMS algorithm doesn’t take into account. At last, the paper analyzes the dental noise from dental drills and simulates the performance of FXLMS algorithm in different situations, such as different reference signals and different noises.
