A gadget to manage dental phobia/fear/anxiety caused by noise of dental drill
Few days back I wrote about - Dental Phobia/fear/Anxiety - Causes & Management - Here
(For tumblr & Posterous users)
& there I mentioned that fear of noise generated by dental drills is one cause for dental phobia/fear anxiety. But now it seems like researchers have created a device which help people overcome their fear of dentists- by canceling out the sound of the drill.
| Experts at Brunel University say the anxiety-inducing sound can be eliminated by using their gadget which plugs into an MP3 player. This then uses a microphone and adaptive filtering to cancel out the high-pitched drill noise, while allowing the patient to hear the music and what their dentist is saying. |
