In measurements of sound pressure or loudness of sound, one pascal is equal to 94 decibels SPL. The quietest sound a human can hear, known as the threshold of hearing, is 0 dB SPL, or 20 ÂµPa. The airtightness of buildings is measured at 50 Pa.
WEAVER++ defines phonological encoding as the process by which the phonological code (i.e., phonemes or syllables) of a word is retrieved and reassembled in an incremental, just-in-time manner to allow for efficient construction of phonological words.
A definition of the term encoding variability principle is presented. The principle was formulated by the American psychologist Gordon Howard Bower. Encoding variability refers to the degree of variability in the environment and mood in which one learns the same material.
