Device for Providing Real-Time Rotorcraft Noise Abatement Information
Rotorcraft typically operate near the ground throughout the duration of the operation. For this reason, military rotorcraft are vulnerable to acoustic detection, and public acceptance of civil rotorcraft is limited by annoyance caused by rotor noise radiation. The purpose of...
Briefs: Electronics & Computers
Many applications require detection of both very small and very large signals. High-gain detector amplifiers provide low noise, but are easily swamped by large signals. Logarithmic amplifiers provide a...

Researchers at NASA’s Glenn and Langley Research Centers have developed a groundbreaking bio-mimicking acoustic liner for quieting noisy environments. Conventional approaches have not been able to absorb...
Briefs: Communications
Microphones, from those in smartphones to hearing aids, are built specifically to hear the human voice — humans can’t hear at levels higher than 20 kHz, and microphones max out at...

NASA’s Langley Research Center has developed a landing gear cavity modification that reduces noise produced during aircraft approach and landing. The modification is an innovative stretchable...
Briefs: Test & Measurement
Time of flight is an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. In time-of-flight imaging, a short burst of light is fired...
Briefs: Electronics & Computers
A new approach was developed that overcomes the limitation of conventional chip-testing methods on 3D chips, which include many thin horizontal “floors” connected to one another by vertical...
