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…

This paper describes four computer-based learning sessions that were designed for and used in the speech acoustics and perception sections of a course in Speech Science offered by the Department of Communicative Disorders at the University of Western Ontario. Students…

There is evidence that song bird species produce, recognize, and discriminate song notes on the basis of frequency within a range. How song birds do this is unknown. One hypothesis is that song birds represent individual frequencies separately, somehow knowing…

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…

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…

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…
