This Audio Precision technote discusses MEMS microphone and mic array measurements, including important considerations and a detailed example test procedure. In this technote, we discuss MEMS ...
In anticipation of the first flights of its supersonic X-59 Quiet SuperSonic Technology (QueSST) X-plane, NASA recently tested a microphone that's 30 miles (48 km) long. Spread out on the Mojave ...
Quiet supersonic jets may one day fly over land to offer faster commercial and passenger flights. Before that can happen, however, the FAA will need to establish new rules regarding these typically ...
The position and the strength of sound sources radiated by an aircraft model in the wind tunnel can be measured with a microphone array. By means of a large number of microphones which are usually ...
Beamforming techniques are at the forefront of modern acoustical signal processing, enabling precise spatial filtering by harnessing arrays of microphones. These methods exploit constructive and ...
