Auditory Processing (also called Central Auditory Processing) refers to the means by which we make sense of what we hear. "Auditory Processing Disorders" refers to the abnormal interaction of hearing, neural transmission and the brain's ability to make sense of sound. People with auditory processing disorders may indeed have normal hearing, but they have difficulty understanding auditory information. This may…

To get a feel for decibels, look at the table below which gives values for the sound pressure levels of common sounds in our environment. Also shown are the corresponding sound pressures and sound intensities. From these you can see that the decibel scale gives numbers in a much more manageable range. Table of Sound Pressure Levels and Corresponding Sound Pressure…

By Dr. Max S. Chartrand Ph.D. Development of human hearing reveals measurable patterns and differences between the sexes. Some of these appear to be transitory during early development. Others seem to become established over time, often defining educational and occupational goals. New Findings May Shed Light on how the sexes differ in hearing. Because information about life and one's place…
