Researchers have created a device which they claim could help people overcome their fear of the dentists, by cancelling 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.
It's hoped use of the device could encourage more people to visit the dentist as it's the sound of the drill which is said to prevent many people from seeking treatment.
