New Device Removes Noise Caused By…Dental Drills

From London comes the latest “why didn’t I think of that” application for noise-canceling technology!
We can think of very few people who enjoy going to the dentist. You have to hold your mouth open and still while your teeth and gums and poked and prodded, and worst of all is that lingering fear of the drill. You can probably already hear that high-pitched whining in your head, picturing your powertool-wielding dentist boring a hole into your face.
One day, you’ll probably thank King’s College in London, England, for a new device they’ve developed to remove dental drill noise. With this innovative technology, you simply plug a pair of headphones into the device (then into an mp3 player if desired), and it blocks out the drill’s noise while still allowing you to hear the dental staff talk to you. The device uses the same concept as noise-canceling headphones, which contain a microphone that analyzes incoming sound waves and produces an inverted wave to cancel out the sound.
You’re still responsible for proper brushing and flossing, but the next time you get a cavity, you can be assured that all will be quiet and peaceful during your nitrous oxide and Novocaine-induced bliss.
