The effect of musical experience on listening effort processes is among the controversial issues in the literature. Considering this uncertainty in the literature, the aim of this study is to investigate the effect of musical experience on listening effort processes by comparatively examining the listening effort experienced in challenging communication environments in musicians and adults with no musical experience. In this way, it is purpose to investigate the effect of music experience on listening effort processes. The sample of the study consists of 15 participants with normal hearing for the study group consisting of musicians and 16 participants with normal hearing for the control group consisting of no musical experience adults. After the hearing thresholds of all participants were evaluated by pure tone audiometry, the Montreal Cognitive Assessment test was administered to the participants to confirm normal cognitive function. Listening effort evaluations were carried out with the participants who applied the Turkish Matrix Test to evaluate speech understanding performance in noise. In listening effort evaluations, EEG from the central nervous system and pupillometry measurements from the autonomic nervous system were performed simultaneously. According to the results of the study, there was no difference between the two groups in terms of speech understanding performance in noise. However, a larger alpha power in EEG and a lower pupil size increase in pupillometry were obtained in the study group, reflecting less listening effort compared to the control group. No correlation was found between speech understanding performance in noise and listening effort. The results showed musical experience had a positive effect on listening effort in challenging listening conditions. It is thought that the evidence presented by this study that musical experience modulates auditory, cognitive, and neural responses may contribute to a better understanding of complex listening effort mechanisms.

Speaking, learning and socializing in daily life mostly occur in the presence of intense noise. Therefore, evaluating speech perception in noise is an important element for all age groups. Although there are Turkish tests that evaluate speech recognition performance in noise for children over the age of 6 and adults, there is no speech recognition test in noise suitable for preschool children. This study aimed to create the Word Recognition Test in Noise for Preschool Children and to determine age-specific speech recognition thresholds. In light of this purpose, children's books for children between the ages of 3-6 were examined and those with high recognition were selected and these words were paired with pictures appropriate to the age and cognitive level of the children. Lists were created with 24 words in each list and transferred to tablet-based testing software. 1st group 3 years - 3 years 11 months (26 girls, 20 boys), 2nd group 4 years - 4 years 11 months (26 girls, 25 boys) and 3rd group 5 years - 5 years 11 months (15 girls, It was applied to 138 participants (26 men) twice, in the form of test-retest, with an interval of 15 days. The Signal-to-Noise Ratio (SNR) threshold for speech recognition in noise was determined for each age group. As a result of the study, the SGO values of the Word Recognition Test in Noise for Preschool Children were 1.,2. While -8.1 dB, -8.9 dB and -10.7 dB were obtained for the and 3rd groups, respectively, retest SGO values were obtained as -8.0 dB, -9.3 dB and -11.1 dB, respectively. . These findings were determined to be similar to developmental and speech perception studies in noise conducted for preschool children between the ages of 3-6. No significant difference was detected between test-retest SGO values (p = 0.102). It was concluded that the Word Recognition Test in Noise for Preschool Children is a reliable assessment test to evaluate word recognition skills in noise in young children.

Acoustic change complex (ACC) is a cortical auditory evoked potential in response to a change in a sustained sound. The ACC response evoked by the /ui/ stimulus arise from the onset of the /i/ sound and the F2 formant frequency change that occurs during the transition from /u/ to /i/, but which of these two acoustic events has more effect on the response has not been investigated before. The present study was conducted to investigate the contribution of these two acoustic events to the ACC response. A total of 21 volunteers, 11 females and 10 males, aged 18-30 years, who did not have any psychiatric and neurological problems, no noise exposure, and no hearing pathology, who were not professionally involved in instrumental music, participated in the study. In the study, the /ui/ stimulus was presented in 3 different background conditions: silent condition and +5 dB SNR, masked condition and filtered masked (2400 Hz high-pass frequency) condition. Repeated measures analysis of variance was performed to compare ACC N1 latency values and ACC N1-P2 peak-to-peak amplitudes between conditions. As a result of pairwise comparisons, it was seen that ACC N1 latencies were significantly higher in the filtered masked condition than in the silent condition and the masked condition (p = .038 and p = .022, respectively). In terms of amplitude values, in pairwise comparisons, the filtered masked condition was found to be significantly lower than ACC N1-P2 and the masked condition. (p= .000). There was no statistically significant difference in latency and amplitude between the silent condition and the masked condition. In this respect, the condition in which the /i/ sound was selectively masked was the condition in which the response amplitudes and latencies were significantly affected. The results suggest that the onset of the /i/ sound is the basic acoustic feature that evokes the ACC N1 response evoked by the /ui/ stimulus. In future studies, it may be recommended to use behaviorally determined mask levels, masking filter frequencies and to create more challenging listening conditions.

In this study, it was aimed to evaluate maternal knowledge about hearing loss, their satisfaction with newborn hearing screening programs and parents’ perceived level of stress. The study was carried out with 75 mothers aged 19-46 years whose infants underwent newborn hearing screening at Buca Seyfi Demirsoy Training and Research Hospital. Mothers were analysed in two groups: those with newborn babies and those with young children between 12-60 months. Each group was divided into those who passed the hearing screening test and those who were referred. Maternal Knowledge Level Checklist on Hearing Loss, Parent Satisfaction Questionnaire for Neonatal Hearing Screening Programme and Perceived Stress Scale were used in the evaluation. When the relationship between the level of knowledge, satisfaction and stress factors was analysed, it was concluded that the level of knowledge about hearing loss was negatively correlated with satisfaction with pre-screening information (p<0.05) and positively correlated with overall satisfaction (p<0.05). Overall satisfaction with the screening programme was positively correlated with satisfaction with the staff (p<0.01) and the appointment process (p<0.01). A strong positive correlation was obtained between the total satisfaction scores for the screening programme and satisfaction with staff (p<0.01), appointment (p<0.01) and overall satisfaction (p<0.01), while a negative correlation was obtained with satisfaction with pre-screening information (p<0.01). The correlation between satisfaction with staff and satisfaction with information was negative (p<0.05), while a strong positive correlation was obtained with satisfaction with the appointment process (p<0.01). As a result of the study, no significant difference was observed between the groups in terms of the level of information about hearing loss and perceived stress (p>0,05), while a significant difference was obtained between the satisfaction levels. This difference was thought to be related to the personnel factor. It is thought that the findings obtained will contribute to the improvement of the hearing screening programme.
