A team from the Dental Institute at Kings College London has come up with a nifty little device that will cancel the noise from a dental drill.

Huh??

We’ve been waiting for something like that since the stone age!  It seems as though it will work much like noise cancelling headphones that you use to block out aircraft noises, rampaging children or the occasional spouse.

The idea isn’t new, but the problem has always been that noise cancelling technology works far better for low frequency sound than high frequency.  Enter Brian Millar and his team.  They seem to have solved the problem, and a commercial version is (hopefully) not too far down the road.

Here’s a link to the Scientific American short:

This can’t possibly come soon enough
