| 1168538 | 2011-01-10 06:25:00 | Heard it tonight on Radio NZ and I would say most don't like the sound as it takes you back to when you are about 6/7 years old. My dentist has a LCD screen up toward the ceiling ,I said is it for watching video's while he is working?,no it was for when clients wants to see what he is doing (not live while inflicting pain though) |

| 1168539 | 2011-01-10 07:10:00 | The device is similar to noise cancelling headphones, but while they work on analogue technology - using resistors to suppress low frequency sounds - this device is digital. The BBC got the story all wrong though. Noise cancelling headphone technology is not analogue, it is digital and always has been, and it does not "use resistors" to suppress LF noise, resistors are non-frequency dependent anyway. The dental equipment may have its response fine tuned to the frequency band of a dentist's drill, but in the end any cancellation will be partial only, and bone conduction to the inner ear (via the jawbone and skull) would be largely unaffected, Noise cancelling technology only works effectively on the aural (acoustic) pathways and relies on anti-phase sound waves to cancel the unwanted ambient noise. I use Bose NC headphones when flying and they make a huge difference, but if I rest my head against a hard window surround the apparent noise level increases significantly through bone conduction. I suppose they could build a noise cancelling helmet though, with multiple tranducers pounding away on your skull. :D Cheers Billy 8-{) |

| 1168541 | 2011-01-10 08:56:00 | Ah, good to read a professional "knows what he's talking about" billy. Ever interested knowledge sponge has topped up for today. As for teeth, so far so good. i'll come back when they start ripping them aout :D |

| 1168542 | 2011-01-10 18:24:00 | The sound of the drill??!! I have dentisit phobia. It sure isn't the sound of the drill. There's a bunch of things, not in any kind of order: The sounds of others screaming(I heard that once, some kid they had in there, the excuse was they'd had an accident and needed extensive repairs - so?!! Give the kid some pain killer!) The chair - that they lower until you're lying under the glare The stuff they do to you Local anasthetic The cost |

| 1168543 | 2011-01-10 18:30:00 | . The cost Unfortunately, a lobotomy is the only cure for this.! |

| 1168544 | 2011-01-10 19:43:00 | Lobotomies are possibly effective, and very useful in their place, but consider the after effects - - can we use all these extra trained politicians that will arise for every wisdom tooth extraction or root canal procedure? Remember, there is already a vast surplus of Bellamy entitled dodgy drongos. | R2x1 (4628) | ||
