AI Technical Summary
Noise interference in dental clinics can cause anxiety and fear in patients, affecting their experience, reducing their cooperation, and potentially leading to hearing loss and increased psychological stress for medical staff, thus hindering the smooth progress of surgical procedures.
An active noise cancellation device is used to capture noise signals through a microphone. The active noise cancellation module generates an anti-phase sound wave that is superimposed on the noise to eliminate it. The device also uses a display screen to divert the patient's attention and a timer to remind medical staff, thus achieving noise reduction and psychological relief.
It can effectively reduce or eliminate noise in the examination room, reduce patient anxiety, improve the patient experience, enhance patient cooperation, reduce fatigue and hearing damage of medical staff, and ensure the smooth progress of surgical procedures.
