Dental Drill Noise Cancellation Aims To Make Dental Visits Less Stressful

Dentist

We all dread going to the dentist. The very sound of the drill is more than enough to leave even the toughest of us shaking in our shoes. That is why King’s College Dental Institute’s Professor Brian Millar has invented a noise cancellation device that eliminates the unnerving sound of dental drills.

Many people put off going to the dentist because of anxiety associated with the noise of the dentist’s drill. But this device has the potential to make fear of the drill a thing of the past.
The beauty of this gadget is that it would be fairly cost-effective for dentists to buy, and any patient with an MP3 player would be able to benefit from it, at no extra cost.

Millar lead a team from King’s College London, Brunel University and the London South Bank University to develop the noise cancellation device, which works like noise cancellation headphones: It creates an inverted sound wave to cancel the noise, focusing on the frequencies generated by the drills. The patient would still be able to listen to the dentist and hear other sounds.

The only problem is it doesn’t exactly stop the pain of the drill does it Professor…
