Researchers at Stanford's School of Humanities and Sciences have developed a quantum microphone capable of registering phonons, the smallest-known units of sound. The team used minuscule resonators to measure the energy of phonons, according to an article in Nature. " Instead of relying on indirect measurement of sound waves, the scientists built a device which measures the energy of phonons directly using minuscule resonators which act like mirrors for sound. The acoustic properties of sound are very well understood," said lead author David Deamer from Stanford University.
