Nano Ears

Nano Ears is the most sensitive listening device ever created which can hear microscopic objects like bacteria.By observing the oscillations of a single gold nanoparticle, tiny movements can be detected. 

The nanoear is capable of detecting sound levels of approximately -60 dB. Thus, it is about a million times more sensitive than the hearing threshold of the human ear, which by convention is set at 0 dB. 

Nanoears were developed at the Nanosystems Initiative Munich.
