Frequency Resolution
A fundamental psychophysical measure of the auditory system's ability to distinguish different frequencies. Natural hearing relies on the position of the traveling wave along the cochlear basilar membrane and on hair cell firing rate encoding.
Timeline (last 90 days)
Natural hearing relies on the traveling-wave position along the cochlear basilar membrane and the firing rate of hair cells to encode frequency, with high and continuous resolution.
Cochlear implants provide only a limited number of electrodes (commonly 12 to 22), each corresponding to a relatively wide frequency band, so frequency resolution is significantly reduced and stimulation of adjacent electrodes is often perceived as the same pitch.
