Objective:
To evaluate the abilities speech perception of post-lingual cochlear implant patients by Mandarin Hearing In Noise Test(MHINT), get the performance-intensity function (P-I function).
Method:
The material was MHINT adults' version, including 12 lists, 20 sentences per list. Twenty-two cochlear implant patients were the subjects, age from 14 to 56. Three adaptive rules were used during the test. Firstly Rule 3 would be done. If subject could finish the test, then Rule 2 and Rule 1 would be used. Got the Reception threshold of sentences and speech recognition score of subjects, then got performance-intensity function (PI function).
Result:
Among those 22 subjects, 5 of them could be tested in all three rules, 3 could be tested in Rule 2 and Rule 3, 7 of them could be tested with Rule 3, and 7 of the CI users could not be tested even with Rule 3. All of the PI functions for CI users are shifted 10 dB or more above the normal PI functions. Most CI users thought that MHINT was hard for them.
Conclusion:
When use new adaptive scoring rules for MHINT, most CI users could be tested with the modified HINT scoring rules, although three subjects could not be tested. Compared with normal hearing subjects, all CI users required positive S/N ratios to perform the HINT measures.
