Week 10 Flashcards
Frequency
Pitch
Sound
Pressure waves
Wavelength
Distance in space between successive compressions. Pitch
Amplitude
Height of sound wave, how much force used to create sound. Loudness
Timbre
How many distinct waves are mixed together
Cochlea
Inner ear
Organ of corti
Contains hair cells
Trap door mechanism
Let’s potassium in and depolarizes hair cells
Inner hair cell
Synapses with afferent fiber
Outer hair cell
Synapse with efferent fiber
Physical scale of sound intensity
Decibel scale. Not linear
Measurement methods
Minimum audible pressure vs minimum audible field
Frequency range
Lowest-highest sound frequencies that can be heard by given species. Threshold varies as a function of sound frequency
Dynamic range
Intensity
Amplitude
Loudness
