伍迪.诺里斯（Woody Norris）惊人的发明

Hypersonic sound technology focuses audio as precisely as a laser focuses light. Instead of sound spilling in every direction, it can now be delivered to a single spot or person, even in a crowded space. In one demonstration, a waterfall recording was audible only when the beam was aimed directly at someone's head. This breakthrough opens up possibilities from private TV audio in supermarkets to military communication over great distances.
