audiogram

n. a graph relating an individual’s pure-tone thresholds at selected frequencies to those of people with normal hearing. The x-axis is the frequency of the tone; the y-axis is hearing level (HL), expressed in decibels (dB). For example, a person whose threshold is 30 dB above normal for a 4 kHz tone would have an audiogram that shows a point at 4 kHz and 30 dB HL. The audiogram is a basic clinical measurement for assessing and diagnosing hearing disorders. See audiometer; audiometric zero. Compare audibility curve.

morphometrics

n. the theory and technique associated with the physical measurement of living organisms and their component parts. Studies of size, shape, and structure are important not only in biology but also in neuropsychology and medical psychology. For example, researchers interested in morphometrics could study the form and structure of the brain in individuals who have various physical or psychological disorders. By contrast, psychometrics specifically focuses on the measurement of psychological phenomena.
