Noise Measurements and Noise Measurement Systems [PDF]
The Journal of the Acoustical Society of America, 1969 Only a brief description of the measurement of sound level and sound-pressure level is given in S1.2-1962, American Standard Method for the Physical Measurement of Sound. The initial task of S1-W-51 is to prepare a partial revision of S1.2-1962, which includes recommended procedures for measuring weighted and band-limited sound-pressure levels under ...

Reduction of Classical Measurement Noise via Quantum-Dense Metrology [PDF]
, 2016 Quantum-dense metrology (QDM) constitutes a special case of quantum metrology in which two orthogonal phase space projections of a signal are simultaneously sensed beyond the shot noise limit.

Shot-noise-limited control-loop noise in an interferometer with multiple degrees of freedom [PDF]
, 2010 Precise measurements, such as those made with interferometric gravitational-wave detectors, require the measurement device to be properly controlled so that the sensitivity can be as high as possible.

Observation of Strong Radiation Pressure Forces from Squeezed Light on a Mechanical Oscillator
, 2016 Quantum enhanced sensing is a powerful technique in which nonclassical states are used to improve the sensitivity of a measurement. For enhanced mechanical displacement sensing, squeezed states of light have been shown to reduce the photon counting noise

Back-action cancellation in interferometers by quantum locking [PDF]
, 2003 We show that back-action noise in interferometric measurements such as gravitational-waves detectors can be completely suppressed by a local control of mirrors motion.
