Perceptual Coherence: Hearing and Seeing (Electronic book text)

There are auditory books and visual books, but neither type of book uses the other sense to illustrate the common issues in perception. This volume's comparison of hearing and seeing, or listening to and looking at provides the means to isolate what is common to perception and what is specific to each sensory system. There are only 3 or 4 types of visual receptors, each with overlapping but different wavelength sensitivity, but there are about 2,000 auditory receptors, again with overlapping wavelength sensitivity. Through comparisons such as this one, Handel illustrates how the number and sensitivity of the receptors match the properties of the stimuli.
