Quiz 6 Flashcards
Pitch is perceived based on maximum excitation along the basilar membrane. What model for pitch perception is relevant?
Place model
Bundles of auditory nerve fibers fire at the compression phase of a signal, giving the brain a cue for the period of the signal. What model for pitch perception is relevant?
temporal model
Based on spectral representation of the stimulus (information contained in the spectrum). What model for pitch perception is relevant?
Place model
Based on the waveform of the stimulus. What model for pitch perception is relevant?
temporal model
The duration of a signal can (but may not always) affects what in terms of perception?
perception of tonality
absolute threshold
loudness perception
Which of the following are physical sound characteristics and which are perceptual characteristics?
loudness
intensity or SPL
frequency
pitch
phase
duration
loudness - perceptual
intensity or sound pressure level -physical
frequency - physical
pitch - perceptual
phase - physical
duration - both physical and perceptual
The jnd for frequency (also referred to as dlf) at 1,000 Hz is approximately 5 Hz. The jnd for frequency at 10,000 Hz is approximately 50 Hz. This is an example of
Weber’s law
Frequency selectivity refers to the auditory system’s ability to
detect one sound in the presence of another, different sound
