To understand speech in noisy situations, listeners must not only `extract' the speech signal from the background noise, but also determine the meaning of the words and phrases in the extracted signal, integrate this information with past knowledge, and store…

Geoacoustic properties of the upper tens of metres of ocean bottom sediments can significantly influence low-frequency acoustic propagation in the ocean. Therefore, knowledge of these properties is required for reliable propagation modelling and matched-field processing. To date, however, few measurements…

Each year, complaints are filed at the Quebec and Canadian Human Rights Commission by individuals who have been refused employment because their hearing sensitivity does not meet the standards required by the employer. This paper presents four recent cases. The…

The CHHA survey about hard of hearing youth found that access is a major difficulty. In asking young hard of hearing persons about their experiences in everyday life, the survey found that about half had difficulty, watching television, over half…

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…

Observed psychoacoustic events are often incompatible with musical knowledge. The point has been made particularly in the realm of pitch theory. This paper will contend that it is not the case that musical knowledge does not apply to psychophysical tasks…

Innovation implies managing knowledge in a creative way in order to respond to the requests coming from the market and to other social needs. Communication and human interaction contribute a lot in this direction. Innovation provides a great challenge for…

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…

A investigation was conducted to evaluate six 'green' office buildings acoustically to learn design lessons. It involved a meeting with designers, performing an occupant satisfaction survey, analyzing the acoustical responses, walking through the building, and planning acoustical measurements. The results…
