Toward Quieter Dental Devices: Transient CFD Simulation of Airflow and Noise in Air Turbine Handpieces

High-pitched noise generated by dental air turbine handpieces (ATHs) causes discomfort and anxiety, discouraging dental visits. Understanding the time-dependent noise generation mechanism associated with compressed airflow in ATHs is crucial for effective noise reduction. However, the direct investi...
