Abstract:

Acoustic measurements in the frequency range between 4.5 to 4500 cycles per second were made on the near field sound pressure environment produced by the F-101B, NF-102A, and F-106A turbojet aircraft during ground runup operations. Results from twentyeight microphone locations show that the maximum infrasonic noise below audio frequency range is generated downstream from the exhaust nozzle and at engine settings producing maximum turbulent flow.
