| ABSTRACT |
|
The present study examined performance of 10 normal-hearing listeners (control group) and 10 cochlear implant (CI) users who had
CI on one ear and HA on the opposite ear (CI+HA) in order to investigate the amount of binaural benefit on K-HINT (Korea-Hearing
in Noise threshold) test. Additionally, a K-SSQ (SSQ translated in Korean) survey was also conducted to all CI participants in
order to evaluate their subjective benefit from the use of CI+HA. Results of the K-HINT test for YNH and CI participants were as
follows. For YHN listeners, -7.2 dB SNR, on average, was required to identify K-HINT sentences by 50%. For CI users, 15.32 dB
SNR was needed for 50% of K-HINT sentence identification during CI-only listening condition whereas 11.82 dB SNR was required
for 50% of K-HINT sentence identification during CI+HA listening condition. CI users’ binaural benefits calculated from K-HINT
results were 4.6 dB signal-to-noise ratio (SNR), 3.4 dB SNR, and 3.8 dB SNR for head shadow effect, binaural squelch, binaural
summation effects, respectively. Results of K-SSQ survey suggested that the degree of satisfaction was around 62%, regardless of
three sections (speech, spatial and quality) in K-SSQ. CI users recieved a significant benefit from binaural use (CI+HA), regardless
of the direction of noise. |
