Soothing sounds – can technology beat sound of the dental drill?

Boffins have devised some technical wizardry using digital sounds methods to cancel out the sound of the dentist’s drill.
This, they hope, will help patients overcome any fear or dislike of the drill noise. Will be interesting to see the finished product. See the article by clicking the link below…
We’ve taken that whole topic into account when we devised the new clinic and have installed a sophisticated music and entertainment system aimed at helping our patients.
While in the chair our patients can watch a DVD movie of their choice, tune into a TV show or even bring along their own iPod so the music selection can help soothe them.
We hope the combination of our relaxed, welcoming environment with some self-selected entertainment gives our patients the best possible experience while we look after their dental needs.
