University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision ...

Physicists have discovered that placing a particle at the center of a mirror can silence quantum noise by making it ...

Electrical noise, like taxes, is always with us. Most of the time noise is small and we can ignore it, but there are some measurement circumstances where noise must be dealt with. What can be done to ...

Not only does the noise affect the measurements of fragile systems like an ultra-precise quantum sensor, but it can also make the system less manageable. Shitara elaborates, "The problem becomes a ...

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for automotive radar sensors at 80 GHz using the interferometric measurement approach in ...

After digging into the service manual of the related E5052B unit, [Shahriar] notes that the phase noise measurement part of the instrument is totally separate from the power measurement ...

13 microphones installed on a wing extending 2.7 m on either side and traversed 4 m fore and aft of the hub center, complemented by 2 nozzle microphones and 3 additional ones at the ceiling.This ...

The Times is collecting personal stories and noise measurements from readers like you. By Emily Baumgaertner Emily Baumgaertner has been reporting on noise pollution and its effects on public ...

We went to neighborhoods in rural Mississippi, New York City, and suburban California and New Jersey to measure residents’ noise exposure and interview them about the commotion in their lives.
