Temporal resolution skills in Cochlear implant users in relation to post implant age

Mukesh Sharma

Abstract :

Cochlear Implant (CI) is a device that helps adults and children who have severe to profound heå loss and are not receiving satisfactory benefit from heå aids or tactile devices to understand speech. Temporal resolution is an auditory temporal processing skill that refers to the minimal time required to segregate or resolve acoustic events. Gap detection is probably the most commonly used measure of temporal resolution. 20 children with cochlear implant in the age range of 7–20 years were included in the study. Gap Detection Threshold was measured at 500Hz, 1K Hz, 2K Hz, 4K Hz in four groups i.e., are cochlear implant recipients with 2, 5, 10 and 15 months of post–operative duration. Significant (p<0.001) difference in gap detection threshold between 2 and 5, 10 and 15 months observed for all frequencies. No significant difference observed between 5 months to 10 and 15 months and between 10 and 15 months for all the test frequencies. Poor temporal resolution is seen in CI because they rely on either temporal or spectral cues. Poorer scores soon after the implants could be due to the training, implant duration or the initial map current levels.
