Scientists create worlds smallest Ear

Wissenschaftler haben ein „Nano-Ohr“ gebaut, um damit die Geräusche von Viren und Bakterien zu hören. Akkustische Mikroskopie nennen sie das.

Have you ever wondered what a virus sounds like? Or what noise a bacterium makes when it moves between hosts? If the answer is yes, you may soon get your chance to find out, thanks to the development of 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.
