A Case of MAP Verification of Cochlear Implant Using Audible Field

Objective: The aims of this study will be discussing MAP verification, by using implanted most comfortable loudness level (MCL), uncomfortable loudness level (UCL) in audiological evaluation and speech language pathological (SLP) evaluation. Method: An implanted university student who has low performance participated. MAP was verified for listening and communicational performances by audiological and SLP evaluation. Results: Implanted hearing threshold level was observed within normal limits in all test frequencies. Suprathreshold listening capability was observed at lowered level in MCL of 250 ㎐ and UCL of 750, 1,000, 1,500㎐. This results support causes of many kinds of error that appeared in SLP evaluation. Conclusion: MAP verification needs to do a cross-check on suprathreshold evaluation, SLP evaluation and also chief complaint.
