Scientists Create World's Tiniest "Ear"

Posted by samzenpus on from the for-the-little-voices dept.

sciencehabit writes "If you've ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world's tiniest ear. The 'nano-ear,' a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of 'acoustic microscopy,' in which organisms are studied using the sound they emit."

    If I wanted to know what parasitic bacteria sound like, I could just as easily turn on C-SPAN.

    Possibly by substracting a second signal from a microphone that does *not* capture the sound of a single bacterium? Something like active noise cancellation.

    I would call it a microphone, but maybe that wouldn't prick up many ears.
