Originally published in 1976, this introduction to hearing was intended to provide a sufficient introduction to each of several subareas of hearing so that the serious student can read the more advanced treatments with greater appreciation and understanding. It was intended for upper graduate and graduate students. It assumes some mathematical sophistication – calculus for example, but there is some review of more basic concepts, such as logarithms. There is also a brief treatment of the necessary material from the different disciplines – physics, physiology, psychology, anatomy and mathematics – that a student of hearing will need to know.

Some 300 species of amphibians inhabit North America. The past two decades have seen an enormous growth in interest about amphibians and an increased intensity of scientific research into their fascinating biology and continent-wide distribution. This atlas presents the spectacular diversity of North American amphibians in a geographic context. It covers all formally recognized amphibian species found in the United States and Canada, many of which are endangered or threatened with extinction. Illustrated with maps and photos, the species accounts provide current information about distribution, habitat, and conservation. Researchers, professional herpetologists, and anyone intrigued by amphibians will value North American Amphibians as a guide and reference.

This book reviews recent research on the ability of human listeners to discern changes in the shape of complex acoustic spectra-what is known as auditory profile analysis. It also discusses in a systematic way issues surrounding the discrimination of a change in acoustic intensity and the physiological mechanisms responsible for these discrimination processes. The author concludes with two new theories that provide a way of understanding more complex auditory skills, such as those involved in listening to music and speech. This book will be of interest to psychoacousticians, psychophysicists, physiological psychologists, and experimental psychologists.
