What does the critical band refer to in auditory perception?
What does the critical band refer to in auditory perception?
- The band of frequencies that have the highest firing rate on the basilar membrane
- The band of frequencies that are detected by the JND
- The band of frequencies that interfere and mask each other (correct)
- The band of frequencies that the brain cannot differentiate between
How is the Just Noticeable Difference (JND) related to the critical band?
How is the Just Noticeable Difference (JND) related to the critical band?
- JND maps almost perfectly onto the critical band, suggesting a connection (correct)
- The JND determines the upper limit of frequencies within the critical band
- The JND is a measure of pitch perception while the critical band is a measure of loudness perception
- JND and the critical band are unrelated phenomena in auditory perception
According to Bekesy's Place Theory of Hearing, how is the frequency of sound indicated?
According to Bekesy's Place Theory of Hearing, how is the frequency of sound indicated?
- By the amplitude of sound waves entering the cochlea
- By the thickness of the oval membrane connected to the round window
- By the firing rate at different points along the basilar membrane (correct)
- By the speed at which sound waves travel through the ear canal
