Note: NH = normal hearing; UHL = unilateral hearing loss; CI = cochlear implant; HA = hearing aid; SD = standard deviation; thresholds are averaged for responses .25-6 kHz in decibels hearing level (dB HL);
+
indicates the threshold could be greater in cases where there was no response at the limits of the audiometer or limits attainable in the sound field
*
for CI and HA participants, thresholds were obtained with the device in the sound field **for UHL, CI and HA participants, thresholds represent unaided values
