Document Summary
Acoustic energy in a sound for a speech (i. e. vowels) Formants: they"re peaks in the frequency spectrum of that sound. Vowels are harmonic sounds with these very regular intervals of high energy frequency levels going in regular steps (e. g. 200 hz, 300 hz& so on) At least 3 formants for a vowel! A vowel is not identified by the pitch, so not by the fundamental frequency itself but rather where these formants are relative to the fundamental frequency and relative to each other. Formants are good for distinguishing between different vowels; helps us with perceiving speech essentially! touch in an active way! Proprioception: kinaesthetic receptors in our muscles, tendons, and joints; these receptors are also sensing mechanical displacements essentially. Rate of adaptation: slow or fast depending on the receptor so we pick out diff. information that way. Mechanoreceptors are sensory receptors that are responsive to mechanical stimulation, such as pressure and vibration.
