Abstract
Objectives: Evaluating adjustments to cochlear implant (CI) settings is challenging as recipients need time to adapt for optimal speech test performance. The Spectro-Temporal Ripple for Investigating Processor EffectivenesS (STRIPES) test, a language-independent measure of spectro-temporal resolution, has been validated with Advanced Bionics and Cochlear CI systems. This study investigates if performance on the STRIPES test varies with presentation level in a loudspeaker setup and its relationship with outcomes on the British Coordinate Response Measure (CRM) test. In addition, it extends the use of STRIPES and its online version "webSTRIPES" to Med-El CI systems.
Design: A prospective, single-blind, two-session repeated-measures study was conducted with 10 CI users. The first session included three blocks: pre-test webSTRIPES, STRIPES at three loudspeaker presentation levels (50, 65, and 75 dB SPL), and post-test webSTRIPES. The second session measured the speech reception threshold (SRT70) for CRM sentences with a time-reversed speech masker, presented at the same three levels.
Results: Presentation level did not significantly affect STRIPES ripple density thresholds or SRT70 for CRM sentences. A significant correlation was found between STRIPES loudspeaker and webSTRIPES thresholds. WebSTRIPES showed good-to-excellent test-retest reliability. The correlation between CRM SRT70 and STRIPES thresholds, while in the predicted direction, was not statistically significant, likely due to the small sample size (n = 7), which may have limited the power to detect a meaningful relationship.
Conclusions: STRIPES and webSTRIPES ripple density threshold scores can be reliably measured with Med-El CI systems, unaffected by presentation level. The STRIPES test is a promising tool for assessing adult CI listener outcomes without requiring prolonged acclimatization to programming changes.
期刊介绍：
From the basic science of hearing and balance disorders to auditory electrophysiology to amplification and the psychological factors of hearing loss, Ear and Hearing covers all aspects of auditory and vestibular disorders. This multidisciplinary journal consolidates the various factors that contribute to identification, remediation, and audiologic and vestibular rehabilitation. It is the one journal that serves the diverse interest of all members of this professional community -- otologists, audiologists, educators, and to those involved in the design, manufacture, and distribution of amplification systems. The original articles published in the journal focus on assessment, diagnosis, and management of auditory and vestibular disorders.
