Array processing techniques such as beamforming or matched field processing require accurate knowledge of the location of individual elements in the array. For horizontal arrays laid on the ocean floor, relative arrival times measured across the array from nearby implosive…

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.

The characteristics of lawsuits involving hand-arm vibration (HAV), the medical issues involved, and the strategies of defense and plaintiff attorneys as noted in a particular occupational medicine practice, are outlined. The study finds that there is widespread lack of physician…

A novel method of detection and classification for marine mammals is presented which uses techniques from independent component analysis to solve the blind source separation problem for North Atlantic right whales (Eubalaena glacialis). Using the fundamentally non-Gaussian nature of marine…

The emphasis is put on the hierarchical structure, independence and sparseness aspects of auditory signalrepresentations in high-dimensional spaces, so as to define the components of auditory objects. The conceptof an auditory object and its neural representation is introduced. An illustrative…

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…

This paper aims to share the experiences gained by migrating a preparatory course in acoustics for candidates applying to the graduate program in audiology or speech-language pathology at the University of Ottawa to an online environment. The course is offered…

The threat to the survival of several whale species and the introduction of the Species at Risk Act (SARA) has highlighted the need for better knowledge about the biology and ecology of marine mammals in Canadian waters. The North Pacific…

This paper attempts to summarize those aspects of noise related to health. In a field in which technology is advancing rapidly and where research into noise-induced bioeffects is unable to keep pace with these advances, no attempt has been made…

Sound intensity and sound power provide useful information to identify and rank noise sources, and to guide the noise control engineer toward an effective solution. This paper describes a case study where solutions proposed without the knowledge of sound power…
