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 ...

Reducing jet noise by controlling turbulence

Airlines and aircraft manufacturers are under increasing pressure to keep noise levels low for airport personnel and for people in surrounding neighborhoods.

Noise research to combat 'wind turbine syndrome'

(PhysOrg.com) -- University of Adelaide acoustics researchers are investigating the causes of wind turbine noise with the aim of making them quieter and solving 'wind turbine syndrome'.

NRL researchers study ways to reduce jet aircraft noise

Advanced military jet aircraft have engines that provide the needed speed and maneuverability. However, with this greater power there is significant noise during takeoff and landing. The noise can impact the public and affect ...

Loudspeakers in jet engines

Unless one is attending an aeronautics convention or going on a trip, noise associated with aircraft engines is rarely tolerable. Different means of significantly reducing that noise are being tested by EPFL's Electromagnetics ...

Researchers develop 'anti-noise' panel for quiet aircraft

Researchers from the University of Twente's CTIT research institute have developed a prototype lightweight panel that uses anti-noise to reduce noise levels inside aircraft. The panels can be used as a replacement for the ...

Birds adjust their singing activity around airport noise

Scientists from the Max Planck Institute for Ornithology in Seewiesen have determined that birds near Berlin's Tegel airport, one of Europe's largest, start singing significantly earlier in the morning than their counterparts ...

Research: Decreasing cabin noise and vibration

Passenger comfort within the cabin is critical to maintenance of a competitive position. EU-funded researchers modified patented vibration-damping technology for use in aircraft.
