In reference [1], it has been shown that low-frequency acoustic power is absorbed at orifice plate and perforated plate terminations. Since relatively high-intensity pulses were used in the study reported in reference [1], the indications were that n

Analyses of impulse time history data from acoustic transmission tests for conical nozzles attached to a pipe show that the internal reflections from the solid contraction and the open area tend to cancel. To gain understanding of the opposing reflec

The potential of using “active noise control” to reduce cabin noise on the external fuselage surface of turboprop aircraft is demonstrated by conducting several laboratory experiments. The principle of active noise control is to reduce the noise

Several multi-lobed m ixers were tested in high bypass exhaust systems to develop a design methodology and noise reduction concepts. These m ixers along with appropriate confluent m ixers were tested with several fan nozzles of different lengths with

A method is described for measuring the acoustic properties of an absorbent material and a duct/nozzle system (with or without airflow) in which a high voltage spark discharge is used as an impulse source of sound. The cross-spectra of the incident,
