Experts unveil 'cloak of silence' (BBC)

Scientists have shown off the blueprint for an "acoustic cloak", which could make objects impervious to sound waves.

The technology, outlined in the New Journal of Physics, could be used to build sound-proof homes, advanced concert halls or stealth warships.

Scientists have previously demonstrated devices that cloak objects from microwaves, making them "invisible".

"The mathematics behind cloaking has been known for several years," said Professor John Pendry of Imperial College London, UK, an expert in cloaking.

"What hasn't been available for sound is the sort of materials you need to build a cloak out of."
