New device drowns out dentists drill noise

Tue, 11 Jan 2011

For some a visit to the dentist is full of fear and trepidation. The sound of the dentist's drill is enough to make some quake in their boots.

However researchers are developing a device that cancels out the sound of the drill, instead the patient can listen to their choice of music on a MP3 player. The headphones use a noise cancelling technology that cancels out dull low frequency wavelengths.

Professor Brian Millar said, "Many people are 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 dear of the drill a thing of the past."

He added, "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."

Although the headphones block out certain wavelengths they will still be able to hear the voice of their dentist when they talk to the patient.

The technology is not ready for mass use just yet so other anxiety treatment should be considered for those who have a real phobia about visiting the dentist to try and get to the root of the phobia.
