    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.

    The effects of adaptive directional microphone on auditory evoked cortical P300 response and speech performance in cochlear implant users
    (2019) Alniacik, Asuman; Akdas, Ferda; 31268365
    Objective: The aim of this study was to evaluate the possible benefits of an adaptive directional microphone in noise by using auditory P300 and speech recognition scores (SRSs) in cochlear implant subjects. Design: The P300 and speech recognition scores were obtained (a) in quiet with an omnidirectional microphone (Quiet OM), (b) in noise with an omnidirectional microphone (Noise OM) and (c) in noise with an adaptive directional microphone (Noise BEAM) to compare the microphone effects. Study sample: Thirty-five cochlear implant subjects (22.87 +/- 1.30 years) Results: The latencies of the P2, N2 and P3 responses as the discrimination potentials were significantly prolonged in the Noise OM condition compared with those obtained in the Quiet OM and Noise BEAM conditions (p < 0.05). The latencies of all responses in the Quiet OM and Noise BEAM conditions were similarly obtained (p > 0.05). SRSs were significantly lower in the Noise OM condition than in the Quiet OM and Noise BEAM condition (p < 0.05). Conclusions: During noise, the adaptive directional microphone system provided a discrimination ability similar to that seen in quiet settings for cochlear implant users.
