2 the active noise control system for dental handpiece and scaler under infection control in dental clinic

摘要

By suggesting a solution for the removal and reduction of noise generated when using automatic dental instruments, patients can receive dental treatment in a more stable state, and dental workers also improve the working environment continuously exposed to high pitch noise. We suggest this noise canceller or reducer to create a better working environment.;In this case, the microphone, the controller, and the speaker, which implements the active noise canceling system, are integrally manufactured to be detachable to sterilize the automatic dental device. The attachment site may be used as the motor part of the primary automatic mechanism, the ear of the secondary patient, and the ear of the dental practitioner to free people from the dentist from noise.;Dental automatic instruments, handpieces, scalers, turbulence, processing, noise, active noise cancellation, noise reduction, frequency offset
