The Machine that Rubs Out Noise

A noisy restaurant, a busy road, a windy day -- all situations that can be intensely frustrating for the hearing impaired when trying to pick out speech in a noisy environment. What if hearing device wearers could choose to filter out all the troublesome sounds and focus on the voices they want to hear? Dr Richard Turner from the University of Cambridge's Department of Engineering believes that this is fast becoming a possibility. He is developing a system that identifies the corrupting noise and &'rubs it out&';.
