Measurements of Acoustic Pressure and Velocity Vector in Source Localization using Acoustic Intensity Sensors
Identifying acoustic sources in terms of their relative location is an important factor in active noise control. Traditional source localization measurements uses scalar pressure sensors which proved to be less accurate. Nehorai et al. proposed a different approach for source localization using vector natured acoustic intensity sensors. Four-dimensional (4-D) intensity based algorithm and three...
متن کاملQuantitative assessment of acoustic intensity in the focused ultrasound field using hydrophone and infrared imaging.
With the popularity of ultrasound therapy in clinics, characterization of the acoustic field is important not only to the tolerability and efficiency of ablation, but also for treatment planning. A quantitative method was introduced to assess the intensity distribution of a focused ultrasound beam using a hydrophone and an infrared camera with no prior knowledge of the acoustic and thermal para...
متن کاملMale sperm whale acoustic behavior observed from multipaths at a single hydrophone.
Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolated results from biosonar tests made on some small odontocetes. The authors propose a passive acoustic technique requiring only one hydrophone to investigate the acoustic b...
متن کاملEvaluation of underwater acoustic propagation model (Ray theory) in a river using Fluvial Acoustic Tomography System
Underwater acoustics is widely used in many applications, such as oceanography, marine biology, hydrography, fishery, etc. Different models are introduced to simulate the underwater acoustic propagation in the oceans and the seas. In this study, the Ray Theory model is used to simulate the acoustic wave propagation in a shallow-freshwater river (Gono River) located in western part of Japan. The...
متن کاملBeam Patterns of an Underwater Acoustic Vector Hydrophone Located Away From Any Reflecting Boundary
A vector hydrophone is composed of two or three spatially collocated but orthogonally oriented velocity hydrophones plus an optional collocated pressure hydrophone. A vector hydrophone may form azimuth-elevation beams that are invariant with respect to the sources’ frequencies, bandwidths and radial location (in near field as opposed to the far field). This paper characterizes the spatial match...
