Noise control and cancellation over a spatial region is a fundamental problem in acoustic
signal processing. In this paper, we utilize wave-domain adaptive algorithms to iteratively …

An acoustic vector-sensor (also known as vector-hydrophone in underwater applications) is
composed of two or three spatially collocated but orthogonally oriented acoustic velocity …

An active control system based on the acoustic energy density is investigated. The system is
targeted for use in three-dimensional enclosures, such as aircraft cabins and rooms. The …

A new scheme is herein proposed to localize an acoustic source. This new method blends
the" received signal strength indication"(RSSI) approach of geolocation, and the acoustic …

An alternative pressure-sensor based method for estimating the acoustic intensity, the phase
and amplitude gradient estimation (PAGE) method, is presented. This method uses the …

By using the 3D intensimetry algorithm, a sensor probe has a significant advantage at low
frequencies, allowing for a compact array cluster that is far smaller than a wavelength. A …

Three multimicrophone probe arrangements used to measure acoustic intensity are the four-
microphone regular tetrahedral, the four-microphone orthogonal, and the six-microphone …

An acoustic direction-finding and blind interference rejection algorithm for up to three
noncooperative wideband, fast frequency-hop (FFH) spread spectrum signals of unknown …

Near-field characterization of the acoustical environment near rockets has often involved
extrapolating far-field measurements. However, because far-field amplitude data reveals …

This paper proposes a new configuration of acoustic sensors-the collocation of three
cardioid sensors in perpendicular orientation, in order to increase the mainlobe-to-sidelobe …
