Shallow water acoustic response functions at high frequencies and large bandwidths exhibit spatio- temporal variability that depends greatly on the propagation media's volume and boundary conditions as well as system source-receiver motion. For this reason practical acoustic systems invariably must…

A nonlinear Bayesian formulation is applied to study uncertainty in ocean acoustic source localization due to uncertainty in the knowledge of ocean environmental properties. Localization uncertainty is quantified in terms of probability ambiguity surfaces (PAS), which consists of joint marginal…

The features of sound pressure measurements over reflective ground for compact source radiating broad-band noise, are described. The nature of a sound field generated by a broad-band source located above a reflecting surface, is also described. The mean-square sound is…

The book is about diagnostic ultrasound imaging authored by Dr. Thomas L. Zabo. Graduate students in medical physics and biomedical engineering with backgrounds in calculus, complex numbers and some knowledge on electric circuits would benefit from this book.

Infrasound is discussed in terms of what it actually is, how the media has dealt with it and what those with limited knowledge say about it. The perception of infrasound occcurs at levels higher than the levels produced by wind…

The risk of noise induced hearing loss, when wearing a hearing protector, can only be calculated with the knowledge of the noise level at the protected ear. Several methods are available for calculating this level, from the hearing protectors' attenuation…

Unlike porous models developed for particular absorbing materials and frequency ranges, the Johnson-Champoux-Allard model is a generalized model for sound propagation in porous materials over a wide range of frequencies. This model is nowadays used widely across the acoustic research…

Bayesian inversion is applied to estimate the joint posterior probability density (PPD) of geoacoustic parameters. The PPD is sampled by a reversible-jump Markov chain Monte Carlo (rjMCMC) algorithm, which uses an extended Metropolis-Hasting (MH) criterion that allows trans-D jumps between…

A passive acoustic localization method for tracking the movement of a clicking sperm whale in three-dimensions using data from just one hydrophone is demonstrated using data made available for the 3rd International Workshop on Detection and Classification of Marine Mammals.…

Over the last twenty years, many subjectively relevant objective room-acoustics quantities or indicators for evaluating the acoustical quality of an enclosure have been introduced. Whilst indicators give new insight into the acoustical goodness of a receiver position, there is still…
