loudness. height of waves. measured in decibels

frequency

pitch. wavelength. measured in hertz

malleus, incus, stapes

3 bones in middle ear

cochlea

auditory nerve

cranial nerve. axons of all the auditory afferents

oval window

middle ear. where the sound wave enters the inner ear

outer ear function

boost sound pressure

middle ear function

sound amplification

inner ear function

sensory transduction

round window

“exit point” glue so sound wave doesn’t do too much damage

vestibular canal, tympanic canal, and cochlear ducts

fluid filled compartments

organ of corti

receptors that the signals to transduction are located
