“…The current study did find that the change in CNC phoneme scores was positively correlated with the change in HISQUI scores from baseline to 1 year after CI ( r = 0.743, p = 0.034, n = 8). This finding is similar to that found in other studies regarding HISQUI scores and speech outcomes after CI (36–38). It is important to note that there were many missing data points for each quality-of-life measure.…”

ObjectiveTo characterize the degree to which individual coping strategies may influence speech perception after cochlear implantation.Study DesignRetrospective cohort study.SettingTertiary referral center.PatientsAdult, postlingually deaf cochlear implant recipients.Intervention(s)The Coping Orientation to Problems Experience inventory, a validated, multidimensional self-reported coping scale, was administered preoperatively.Main Outcome Measure(s)Speech perception was measured using consonant-nucleus-consonant (CNC) phoneme and word scores, AzBio sentence accuracy in quiet and noise, and Hearing in Noise Test sentences in quiet preoperatively and at 1, 3, and 6 months postoperatively. Quality of life was measured with the Hearing Implant Sound Quality Index and the Nijmegen Cochlear Implant Questionnaire.ResultsThirty-six patients were included in this study. Mean age at surgery was 70.7 ± 11.4 years. Acceptance was associated with a decreased AzBio in noise score in the 6 months after CI (regression coefficient b = −0.05; 95% confidence interval [CI], −0.07 to −0.03; p < 0.01). Denial was associated with a decreased AzBio in quiet score (b = −0.05; 95% CI, −0.09 to −0.01; p < 0.05), whereas humor was associated with an increased AzBio in quiet score (b = 0.02; 95% CI, 0.01 to 0.04; p < 0.05). Humor was also associated with an increased Hearing in Noise Test score (b = 0.05; 95% CI, 0.02 to 0.07; p < 0.05). Denial was associated with decreased CNC word (b = −0.04; 95% CI, −0.06 to −0.02; p < 0.01) and phoneme (b = −0.04; 95% CI, −0.07 to −0.02; p < 0.01) scores, whereas substance use was associated with increased CNC word (b = 0.03; 95% CI, 0.01 to 0.05, p < 0.01) and phoneme (b = 0.04; 95% CI, 0.02 to 0.06; p < 0.01) scores. Scores on self-reported quality of life measures were not significantly correlated with coping strategies.ConclusionA variety of adaptive and maladaptive coping strategies are used by postlingually deaf adult cochlear implant users. Denial and acceptance may be more predictive of poor speech performance, whereas humor and substance use may be more predictive of improved speech performance.

“…The reason for this is the ideal suitability of the beamformer for this audiometric setup. This argument does not question the benefit of the beamformers, but in the context of the known problems of CI patients in noisy environments [ 1 , 42 ] this result raises doubt concerning the ecological validity of this particular measurement setup, i.e., S0N90 with stationary noise. This contradiction was recently pointed out by Badajoz-Davila and Buchholz [ 2 ]: “...standard speech-in-noise tests overestimate the performance of cochlear implant recipients in the real world.…”

Background Nowadays, cochlear implant (CI) patients mostly show good to very good speech comprehension in quiet, but there are known problems with communication in everyday noisy situations. There is thus a need for ecologically valid measurements of speech comprehension in real-life listening situations for hearing-impaired patients. The additional methodological effort must be balanced with clinical human and spatial resources. This study investigates possible simplifications of a complex measurement setup. Methods The study included 20 adults from long-term follow-up after CI fitting with postlingual onset of hearing impairment. The complexity of the investigated listening situations was influenced by changing the spatiality of the noise sources and the temporal characteristics of the noise. To compare different measurement setups, speech reception thresholds (SRT) were measured unilaterally with different CI processors and settings. Ten normal-hearing subjects served as reference. Results In a complex listening situation with four loudspeakers, differences in SRT from CI subjects to the control group of up to 8 dB were found. For CI subjects, this SRT correlated with the situation with frontal speech signal and fluctuating interference signal from the side with R2 = 0.69. For conditions with stationary interfering signals, R2 values <0.2 were found. Conclusion There is no universal solution for all audiometric questions with respect to the spatiality and temporal characteristics of noise sources. In the investigated context, simplification of the complex spatial audiometric setting while using fluctuating competing signals was possible.

“…This study was performed according to a single-subject design with repeated measurements. Feedback was obtained from patients by using the German version of the Hearing Implant Sound Quality Index (HISQUI19) questionnaire (41,42). In-lab characterisation of speech communication abilities was performed by a set of speech tests in quiet (monosyllabic words) as well in noise (adaptive matrix test).…”

Introduction: Audiometric methods for hearing-impaired patients are constantly evolving as new therapeutic interventions and improved clinical standards are established. This study was aimed at evaluating the relationship between cochlear implant (CI) users' subjective judgement of everyday communication situations and results from various speech-audiometric test procedures. To reconstruct challenging everyday listening situations in the clinic to different degrees, the temporal characteristics of the background noise and the spatial arrangement of the signal sources were varied for speech tests in background noise. Methods: In a prospective study, 20 CI-experienced, postlingually deafened users of the Nucleus CI were included. Speech comprehension was measured in quiet (by Freiburg words) and in noise (by the Oldenburg sentence test) while stationary speech-simulating or temporally fluctuating noise was applied and the noise sources were varied from S0N0 through S0NCI to S0N90,180,270. Subjective feedback from the patients was obtained by using the HISQUI19 questionnaire. Results: Word comprehension at 65 dB in quiet showed a significant positive correlation with the user's subjective assessment of hearing ability using the questionnaire (Pearson's R = 0.59). In stationary background noise for the clinically established hearing situation S0N0, there was a negative correlation (R=–0.38, changing to –0.55 in fluctuating ICRA background noise). This trend of greater correlation of the subjective evaluation of comprehension against fluctuating background noise as compared with stationary background noise was also evident in listening situations with spatially separated signal sources, with speech coming from the front and background noise from the side (S0NCI) and from the rear hemisphere (S0N90, S0N90,180,270). On the other hand, the test–retest accuracy was reduced by a substantial factor in the transition from stationary to fluctuating background noise. Conclusions: By introducing temporal fluctuations in the background noise, the ecological validity can be improved, but at the cost of a parallel decrease in the accuracy of the test procedure. Especially in the context of studies, this knowledge may help to improve the adaptation of the test method to the scientific question in evaluating the relationship between ecological validity and precision audiometry.
