Owl wing design reduces aircraft, wind turbine noise pollution

Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise pollution is a major environmental goal for some urban areas.

Internet cable reveals the source of underwater vibrations

Scientists have harnessed Internet-transmitting fiber-optic cables to overcome a long-standing geophysical challenge: identifying where seismic noise in the ocean originates. Tiny vibrations of Earth called microseisms are ...

Researchers advance noise cancelling for quantum computers

A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, "non-Gaussian" noise processes that are routinely encountered in superconducting ...

Quantum computer leap

(Phys.org) -- The main technical difficulty in building a quantum computer could soon be the thing that makes it possible to build one, according to new research from The Australian National University.

Jet engines are getting quieter

With no sign of our appetite for air travel diminishing, we need to create quieter aircraft that are easier to live with. In fact, while those living near airports may beg to differ, data included in the Airports Commission ...
