هل تخاف من طبيب الأسنان؟

Hello and welcome to BBC Xtra English!

Many people around the world are scared of visiting their dentist.

For many of them, the sound of the dentist's drill is a big cause of their anxiety.

Researchers now say that they have invented a device which cancels out the noise of the dentist's drill and could help these people overcome their fear of visiting the dentist.

This new invention allows patients to listen to music on an MP3 player, while the sound of the drill is blanked out.

Patients are still able to hear the dentist's voice because not all sounds are filtered out.

The device is similar to noise cancelling headphones.

It works by turning the sounds of the dental consulting room into a digital signal.

A special chip called a digital signal processor analyses the incoming sound from microphones placed close to the dental drill.

It produces an inverted sound wave to cancel out unwanted noise in the headphone signal.

But this also allows other noises like the dentist's voice to come though.

So a patient could simply plug the device into their MP3 player and then, via their headphones, listen to their own music without being disturbed by the noise of the drill but still be able to hear the dentist.

Developed by experts at King's College London, Brunel University and London South Bank University, it was originally the idea of Professor Brian Millar of King's Dental Institute.

He was inspired initially by the efforts of car-maker Lotus who were trying to develop a system that removed unpleasant road noise, while still allowing drivers to hear emergency sirens.

After more than 10 years of research and collaboration with engineers, Professor Millar and his team have developed a prototype.

He told the BBC that many people are put off going to the dentist because of anxiety associated with the noise of the dentist's drill and that "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."

What is needed now, according to professor Millar is an investor to develop the product further, to help bring the device to as many dental surgeries as possible, and help people whose fear of visiting the dentist stops them from seeking the oral healthcare they need.

I think it's an old Idea to use such device to cancel the noise I heard about a similar device 20 years ago to cancel the noise of kitchen machines like grain grinder and food processor

I think the strong pain is the pain of tooth , in addition to the dentist always does not finish everything in one visit but, he requests from patients to come many times .
as for the new invention , in my opinion nothing can not prevent this strong pain of tooth

I am extremely delighted to run into this subject as this coincided forthcoming appointment to my dentist.
One of the major reasons for me not to have a regular dental checkup is the anxiety I have due to the dentist's drill noise apart from the pain inflicted from the anesthetic shots I have during the treatment.
I am for the invention and solutions contained in your article; and I am willing to invest in such a venture.
