Compilation of quantitative results from multiple peer-reviewed studies examining how different spectral resolution metrics relate to speech recognition performance in adult cochlear implant users under various auditory conditions.
Year: 2008–2025
Population: Postlingually deafened adult CI listeners and typical hearing controls
Sample size: 8–477 participants per study
Mean age at CI implantation: 47–62.5 years
Mean duration of CI experience: 1.83–9.69 years
Type of document: Research summary table
Measurements: Psychophysical tuning curves, spectral-temporally modulated ripple tests, consonant/vowel categorization, spectral modulation detection
Speech perception tests: CNC word recognition, AzBio sentence recognition, K-CID, K-HINT, IEEE sentences, vowel/consonant identification
Main findings: Correlations between spectral resolution measures and various speech recognition outcomes, ranging from non-significant to strong (0.21–0.69)
Global vs. channel-specific measures: Both types analyzed depending on study
Discrimination vs. categorization: Both assessed across studies
Noise conditions: Quiet and multi-talker babble with SNR levels from 0–20 dB
Price: 8 / 10 USD
