Speech recognition difficulties were reported in some CI recipients even with a good-aided hearing threshold. The aim of this study was to report a mapping strategy based on different target-aided hearing thresholds to achieve optimal speech recognition and maximize functional outcomes. The safety and efficacy of the mapping strategy were also inspected in the article.  \nMethods: This prospective repeated measures study enrolled 20 adult CI recipients with postlingual deafness using the MED-EL CI system. Word and sentence discrimination assessment and administration of a questionnaire pertaining to comfort level were conducted at the end of each session. The electrophysiological features of the CI mapping were recorded.  \nResults: The correlation between audiometry results and word and sentence recognition was not high. CIs performed best at an audiometry threshold between 25 and 35 dB.  \nConclusion: CI performance with the best perception relies on a balance between minimizing the hearing threshold and maximizing the dynamic range while maintaining an appropriate comfort level, which was achieved when the target hearing threshold was set at 25–35 dB in this study.  \nKeywords: Auditory perception; Auditory threshold; Cochlear implant; Electrophysiology; Speech perception  \n1. INTRODUCTION  \nCochlear implants (CIs) have become a viable treatment inpatients with severe to profound hearing loss.1 After cochlearimplantation the sound processor must be appropriately programmed and customized for the individual. Parameters of an electrical pattern generated by the internal device in response to sound stimulation must be determined following the CI.2 For the MED-EL system, the minimal electrical stimulation responded to auditory inputs (THR) and the maximal tolerable currents of each electrode (MCL) are assessed during the fitting.3 The collective set of parameters is referred to as a MAP. Several MAPs are tried during a fitting, to determine which MAP yields the best auditory perception.2  \nA major challenge when fitting CI systems lies in compressing the wide range of intensities present in acoustic input signals into the limited range that is available for electrical stimulation.4 However, complications, such as headache, facial nerve stimulation, and unwilling noise, concurred with increased electrode  \n* Address correspondence.
