Document Summary

Sound waves: amplitude: the magnitude of displacement (increase or decrease) of a sound pressure wave. Loudness : frequency: the number of times per second that a pattern of pressure change repeats. It vibrates in response to sound: pinna: the outer, funnel-like part of the ear. Only mammals have pinna, and they vary in size and shape an air-filled chamber containing the middle bones, or ossicles. The middle ear conveys and amplifies: middle ear: vibration from the tympanic membrane to the oval window, ossicle: any of the 3 tiny bones of the middle ear. Malleus: receives vibration from the tympanic membrane and is attached to the incus. Incus: the middle of the 3, connecting the malleus and the stapes. Tensory tympani: the muscle attached to the malleus; tensing decreases vibration. Stapedius: the muscle attached to the stapes; tensing the stapedius decreases vibration a hollow cavity in the temporal bone of the skull,; the cochlea and the semicircular canals of the.
