auricle - external portion of the ear, known as the pinna 2500 Hz - resonant frequency of the ear canal cerumen - ear wax; functions to lubricate and please the canal, protect the ear from fungi/bacteria/small insects tympanic membrane - a membrane forming part of the organ of hearing, which vibrates in response to sound waves. ossicular chain (ossicles) - the three interconnected bones in the middle ear that conduct vibration from the tympanic membrane to the cochlea eustachian tube - c...

Source filter model (4) - ACCURATE ANSWER~ the larynx serves as the sound source and its output is then sent into the vocal tract which filters it. ~ larynx on its on cant produce any sound unless there is pressure driving it ~ pressure comes from the lungs ~ vocal tract doesn't just filter but resonates or enhances some sounds Pitch (2) - ACCURATE ANSWERStretch the vocal folds to increase their tension and therefore increase the frequency at which they will vibrate ~ Contracting the cri...
