The possibility of jet-installation noise reduction has been experimentally demonstrated using a flat-plate fitted with flow permeable metal foam fitted at the trailing-edge. Tests were …
PM10, one of the air pollutants, occurs regularly in İstanbul during the winter months, namely in December, January, and February. PM10 pollutant is affected by numerous factors …
Correlation analyses of ground-based acoustic-pressure measurements of noise from a tethered F-22A provide insights into the sound-field characteristics with position and engine …

Crackle, the impulsive quality sometimes present in supersonic jet noise, has traditionally been defined in terms of the pressure waveform skewness. However, recent work has …
Infrasound (low‐frequency acoustic waves) has proven useful to detect and characterize subaerial volcanic activity, but understanding the infrasonic source during sustained …
