“…Another factor supporting the value of the Schroeder-phase test is that performance on this task correlates significantly with the established CNCword identification task (Peterson and Lehiste 1962;Thornton and Raffin 1978) for AVG, MLTF, and 50-Hz Schroeder-phase discrimination scores. Evidence suggests that vowel and consonant recognition are correlated with temporal modulation sensitivity (Cazals et al 1994;Fu 2002).…”

The temporal fine structure (TFS) of sound contributes significantly to the perception of music and speech in noise. The evaluation of new strategies to improve TFS delivery in cochlear implants (CIs) relies upon the assessment of fine structure encoding. Most modern CI sound processing schemes do not encode withinchannel TFS per se, but some TFS information is delivered through temporal envelope cues across multiple channels. Positive and negative Schroeder-phase harmonic complexes differ primarily in acoustic TFS and provide a potential test of TFS discrimination ability in CI users for current and future processing strategies. The ability to discriminate Schroeder-phase stimuli was evaluated in 24 CI users and 7 normal-hearing listeners at four fundamental frequencies: 50, 100, 200, and 400 Hz. The dependent variables were percent correct at each fundamental frequency, average score across all fundamental frequencies, and a maximum-likelihoodpredicted threshold fundamental frequency for 75% correct. CI listeners scored better than chance for all fundamental frequencies tested. The 50-Hz, average, and predicted threshold scores correlated significantly with consonant-nucleus-consonant word scores. The 200-Hz score correlated with a measure of speech perception in speech-shaped noise. Pitch-direction sensitivity is predicted jointly by the 400-Hz Schroeder score and a spectral ripple discrimination task. The results demonstrate that the Schroeder test is a potentially useful measure of clinically relevant temporal processing abilities in CI users.

“…Roberts et al (2013) completed a retrospective chart review of 113 patients: 46 younger (<65 years) and 67 older (≥65 years). They reported significant age-related performance differences on the consonant nucleus consonant (CNC; Peterson & Lehiste, 1952) single words tested at 65 dB SPL after at least 5 months of device use. The interval of testing is important in light of reports suggesting older adults take longer to acclimate to electrical hearing compared with younger adults (Chan et al, 2007).…”

Purpose: To determine whether older cochlear implant (CI) listeners differ from younger CI listeners on measures of speech understanding, music perception, and health-related quality of life (HRQoL). In the study, the authors hypothesized that speech recognition would be more difficult for older adults, especially in noisy conditions. Performance on music perception was expected to be lower for older implanted listeners. No differences between age groups were expected on HRQoL. Method: Twenty older (>60 years) and 20 younger (<60 years) implanted adults participated. Speech understanding was assessed using words and sentences presented in quiet, and sentences presented at +15, +10, and +5 dB signal-to-noise ratio conditions. Music perception was tested using the University of Washington Clinical Assessment of Music, and HRQoL was measured using the Njimegen CI survey. Results: Speech understanding was significantly lower for the older compared with the younger group in all conditions. Older implanted adults showed lower performance on music perception compared with younger implanted adults on 1 of 3 subtests. Older adults reported lower HRQoL benefit than younger adults on 3 of 6 subdomains. Conclusion: Data indicate that older CI listeners performed more poorly than younger CI listeners, although group differences appear to be task specific.

“…At each session, one list of 20 sentences was presented to the participant in each testing condition. Monosyllabic word recognition in quiet was assessed with Canadian French monosyllable lists from Benfante et al [18] and the CNC Word Test [19], in free-field, at a fixed presentation level of 60 dB HL. At each session, one list of 50 words was presented to the participant in each testing condition.…”
