Speaker/headset company Turtle Beach has created a new audio system for people with hearing loss that uses ultrasound beams to improve the sound quality for one person, while not making it any louder for the surrounding people—essentially allowing the hard of hearing to enjoy TV or movies with other people around, without having to wear their in-ear hearing aids. The technology behind it is pretty fascinating (and confusing, as all good fascinating technology is) and it certainly makes us feel better about the fact that we're all probably ruining our eardrums by wearing earbuds all the time.
