It is known that the underlying problem in Hidden Hearing Loss (HHL) is cochlear synaptopathy (CS) and that low-spontaneous-rate auditory nerve fibers play an important role in this pathology. Therefore, it is suggested that low-spontaneous-rate auditory nerve fibers are damaged in HHL. Consequently, LS CE-Chirp-evoked ABR and HINT, which assesses CS by presenting stimuli of varying intensities and characteristics to provide information about auditory nerve fibers, will be used to evaluate participants both objectively and subjectively. Aim of the study: The main aim of this study is to investigate the relationship between the amplitude and latency values obtained with LS CE-Chirp-stimulated ABR and the critical Signal-to-Noise Ratio (SNR) obtained from the Hearing in Noise Test (HINT) in individuals suspected of having HHL. Hypotheses H0: In individuals suspected of having HHL, there is no relationship between the amplitude values of waves I, III, and V obtained with LS CE-Chirp ABR at 80, 90, and 100 dBnHL and the I/V amplitude ratio and the critical SNR obtained from HINT. H1: In individuals suspected of having HHL, there is a relationship between the amplitude values of waves I, III, and V obtained with LS CE-Chirp ABR at 80, 90, and 100 dBnHL and the I/V amplitude ratio, and the critical SNR obtained from HINT. Expected Results: The study will reveal how LS CE-Chirp stimulation affects ABR results in individuals suspected of having HHL, and the relationship between these results and HINT results will be examined. In this way, HHL will be evaluated both objectively (LS CE-Chirp ABR) and subjectively (HINT). Based on the findings, scientific outputs such as publications or projects are targeted. Importance: HHL has recently attracted increasing attention as a condition that significantly affects daily life. In today's world, where noise and noisy environments are prevalent, disadvantages arise in many aspects, particularly in communication. Therefore, the findings obtained in this study may contribute to a better understanding of HHL.
