✓ ~~> the time taken for one up-down cycle (wavelength)



Wavelength

✓ ~~> the distance b/w two peaks/an up-down cycle



Universal wave equation

✓ ~~> speed = distance/time = wavelength/period



Higher pitch =

Sound frequency

✓ ~~> - has multiple tones - but there are dominant frequencies

- the avg male voice = 100 Hz (11 foot wavelength)

- the avg female voice = 200 Hz (6 foot frequency)



Sound localization

✓ ~~> - humans are very good at this; use 2 cues:

- the loudness (if its louder in the left ear, it is coming from the left); the time (if

it's coming from the right it arrives to the right ear first)

- neurons on either side compare these things



Ascending auditory pathway

✓ ~~> - cochlear nerve: where sound transduction happens

- 8th cranial nerve/auditory nerve: nerve goes up the brainstem and enters

the rostral medulla

- medulla has 2 nuceli: dorsal cochlear nucleus (has axons that decussate at

the medulla and go to the midbrain; midbrain axons go to the

auditory/medial geniculate thalamus); ventral cochlear nucleus (has axons

that go to the pons - next most rostral part of the brainstem)

- axons terminate bilaterally - affect both hemispheres (bilateral projections)
