Theories of Pitch Perception

The place along the basilar membrane that vibrates the most, determines what pitch is percieved

It is the place in the cochlea, either the vestibular canal, tympanic canal or scala media, which vibrates most that determines what pitch is percieved

The place in auditory space in which the sound is conceived determines what pitch is percieved

The place along the sound wave that reaches the ear first determines what pitch is percieved

(a) The missing fundamental (b) Not all frequencies have been found to have a "place" on the basilar membrane (c) Ability to perceive pitch from broadband stimuli

The rate of vibration of the stimulus determines the perceived pitch

The frequency that is most prominent in an auditory stimulus determines the perceived pitch

Higher frequencies are associated with an increased perception of pitch and decreased frequencies are associated with a lower pitch perception

More frequently heard stimuli are perceived more clearly in terms of their pitch
