Marcos Simon, a PhD candidate at the University of Southampton, has developed a high-volume speaker system that is capable of projecting high-volume audio to specific spots in a room. If you've ever been in a situation where you're watching TV with a group of people and one of them likes to have it turned up really loud, you'll know how this kind of invention might be useful.

These high-volume speakers are actually designed keeping in mind senior citizens who suffer from hearing loss. The system consists of an array of eight loudspeakers arranged in a line -- a line array -- that can focus hot spots of sound to specific areas.

In tests, the array was shown to increase partially def people's ability to understand played-back human speech by 30% without disturbing non-deaf people seated nearby.
