    Subcortical Auditory Processing and Speech Perception in Noise Among Individuals With and Without Extended High-Frequency Hearing Loss
    (JOURNAL OF SPEECH LANGUAGE AND HEARING RESEARCH, 2024-05-16) Colak, Hasan; Aydemir, Berfin Eylul; Sakarya, Merve Deniz; Cakmak, Eda; Alniacik, Asuman; Turkyilmaz, Meral Didem
    Purpose: The significance of extended high -frequency (EHF) hearing (> 8 kHz) is not well understood so far. In this study, we aimed to understand the relationship between EHF hearing loss (EHFHL) and speech perception in noise (SPIN) and the associated physiological signatures using the speech-evoked frequency-following response (sFFR). Method: Sixteen young adults with EHFHL and 16 age- and sex-matched individuals with normal hearing participated in the study. SPIN performance in right speech-right noise, left speech-left noise, and binaural listening conditions was evaluated using the Turkish Matrix Test. Additionally, subcortical auditory processing was assessed by recording sFFRs elicited by 40 -ms /da/ stimuli. Results: Individuals with EHFHL demonstrated poorer SPIN performances in all listening conditions (p < .01). Longer latencies were observed in the V (onset) and O (offset) peaks in these individuals (p <= .01). However, only the V/A peak amplitude was found to be significantly reduced in individuals with EHFHL (p < .01). Conclusions: Our findings highlight the importance of EHF hearing and suggest that EHF hearing should be considered among the key elements in SPIN. Individuals with EHFHL show a tendency toward weaker subcortical auditory processing, which likely contributes to their poorer SPIN performance. Thus, routine assessment of EHF hearing should be implemented in clinical settings, alongside the evaluation of standard audiometric frequencies (0.25-8 kHz).

    Determination of a Cutoff for Noise Sensitivity: Psychometric Evaluation of the Turkish Noise Sensitivity Questionnaire (Tr-NoiSeQ)
    (2022) Alniacik, Asuman; Cakmak, Eda; 35900393
    Context: There is a need for a clear cutoff to use noise sensitivity (NS) scale as a prediagnostic tool in research and clinical use. Aims: Noise sensitivity questionnaire (NoiSeQ) was adapted into Turkish language (Tr-NoiSeQ); validity and reliability of the Tr-NoiSeQ were assessed. The cutoff for the Tr-NoiSeQ was determined. Settings and design: A descriptive study within subject design. Materials and methods: A group of 402 participants aged between 18 and 52 years filled the Tr-NoiSeQ and the Turkish version of Weinstein noise sensitivity scale (Tr-WNSS) via internet. Statistical analysis used: Cronbach alpha (alpha) and the Spearman-Brown coefficient were calculated for the reliability; Pearson correlation coefficient (r) and confirmatory factor analysis (CFA) were used for the validity. The receiver-operating characteristic (ROC) curve was used to calculate cutoff value of the Tr-NoiSeQ. Results: For the Tr-NoiSeQ, Cronbach alpha was 0.92, Spearman-Brown coefficient was 0.93 (P < 0.05). A high significant correlation between the Tr-WNSS and the Tr-NoiSeQ was obtained (r = 0.76, P < 0.05). The fit indexes of the model were obtained as (chi(2) = 1361.06, df = 546, P < 0.001), chi 2 / df = 2.49, root mean square error of approximation = 0.06, comparative fit index = 0.83, goodness of fit index = 0.82. The ROC curve showed that the cutoff for the Tr-NoiSeQ was 53 with a 0.92 sensitivity and a 0.85 specificity (P <= 0.05). Conclusion: The Tr-NoiSeQ is a valid and reliable tool for use in both clinical practice and research. The Tr-NoiSeQ seems to be consistent with the Tr-WNSS and can be used as a screening tool to evaluate NS in audiology.

    Cross-cultural adaptation of the Nijmegen cochlear implant questionnaire into Turkish language: validity, reliability and effects of demographic variables
    (2021) Alniacik, Asuman; Cakmak, Eda; Oz, Okan; 0000-0002-6108-7029; 34837517
    Purpose The purpose of this study was to evaluate the validity and reliability of the Turkish version of the Nijmegen Cochlear Implant Questionnaire (Tr-NCIQ) and reveal the demographic factors contributing to the outcomes. Methods A group of 118 cochlear implant users aged between 18 and 70 years filled the Tr-NCIQ and the Turkish Hearing Handicapped Inventory for Adults (the Tr-HHI-Adult) via electronic survey. Cross-cultural adaptation of the Tr-NCIQ was performed. The reliability and validity of the questionnaire were evaluated utilizing internal consistency coefficient, split-half method, and predictive validity. Results The overall Cronbach's alpha coefficient of the scale was 0.91, and the Spearman-Brown coefficient was 0.91. A moderately significant and negative correlation was present between the basic sound perception, speech production, self-esteem, activity, and social interactions subdomain scores and the HHI-Adult scores. Patients with post-lingual onset of hearing loss had significantly better results than those with pre-lingual onset, in the advanced sound perception subdomain. In addition, bilateral cochlear implant users had better results than the unilateral and bimodal users in the speech production subdomain and then the bimodal users in the self-esteem subdomain. There was no effect of age, duration of implant use, age at implantation, and the daily usage of cochlear implant (CI) on the quality-of-life outcomes. Conclusion The Tr-NCIQ is a reliable and valid tool to evaluate the subjective quality of life in CI users. In addition, as a standardized instrument, it can be easily self-administered both in clinical practice and for research purposes.
