“…In each IN-test and the OUT-test trial, participants listened to two acoustic stimuli segments using headphones set (Sennheiser HD 280 Pro) that was previously investigated and proved acceptable for audiometry screening [23,24]. e noise segment characteristics and silent gap envelope design were described and applied in previous studies [25,26].…”

Currently, several methods are being applied to assess auditory temporal resolution in a controlled clinical environment via the measurements of gap detection thresholds (GDTs). However, these methods face two issues: the relatively long time required to perform the gap detection test in such settings and the potential of inaccessibility to such facilities. This article proposes a fast, affordable, and reliable application-based method for the determination of GDT either inside or outside the soundproof booth. The proposed test and the acoustic stimuli were both developed using the MATLAB® programming platform. GDT is determined when the subject is able to distinguish the shortest silent gap inserted randomly in one of two segments of white noise. GDTs were obtained from 42 normal-hearing subjects inside and outside the soundproof booth. The results of this study indicated that average GDTs measured inside the booth (5.12 ± 1.02 ms) and outside (4.78 ± 1.16 ms) were not significantly different. The measured GDTs were also comparable to that reported in the literature. In addition, the GDT screening time of the proposed method was approximately 5 minutes, a screening time that is much less than that reported by the literature. Data show that the proposed application was fast and reliable to screen GDT compared to the standard method currently used in clinical settings.

“…(referred to as pre-gap) and another succeeding it (known as post-gap). As a result, due to its close resemblance to the shape and physical characteristics of the stimulus, ABR enables the recording of two separate responses-corresponding to the pre-gap segment and another representing the post-gap segment (13,14). This review was conducted to present a thorough examination of the gap in noise auditory brainstem responses, encompassing its methodology, diverse applications, and inherent limitations.…”

“…To develop electrophysiological tests in line with behavioral gap detection tests, studies have been conducted that behavioral GIN thresholds in various groups of patients are closely related to gap detection thresholds in noise, which are determined by GIN-ABR [11,28]. Also, The GIN-ABR holds promise in providing frequencyspecific information to investigate temporal resolution in individuals with diverse hearing disorders [5].…”

This method is valuable to investigate a range of conditions including age-related hearing loss, auditory processing disorders, and tinnitus [4,[8][9][10][11][12][13]. Furthermore, studies have explored the correlation between gap detection thresholds obtained through ABR testing and behavioral thresholds [10,11,14].…”

Background and Objectives: The gap in noise auditory brainstem responses (GIN-ABR) is a valuable assessment tool for auditory temporal processing, offering non-invasive and objective measurements encompassing the entire auditory system from the cochlea to the brainstem. This method has been utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. This systematic review was conducted to present a thorough examination of (GIN-ABR), encompassing its methodology, applications, and inherent limitations. Methods: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Cochrane, PubMed, and Ovid databases were used to extract English articles from 1990 to June 2023. The search terms used were “gap in noise auditory brainstem response”, “ABR gap detection”, “ABR gap duration”, “ABR gap threshold”, and “ABR temporal processing”. Articles were included if gap-evoked ABR was used, investigating the effect of any factor on the responses, and using any gapped stimulus type. Articles whose evoked potentials did not include ABR waves were excluded. The outcome of interest was gap-evoked ABR in different participant groups. Results: A total of 10 studies were deemed suitable for inclusion in the review. The articles were reviewed that including the study population, the methods, and the results. Despite the variability in the results of the studies, in the aged group, longer latency shifts and decreased peak amplitude were reported compared to the young group. Correspondence of behavioral thresholds with GIN-ABR has also been mentioned in studies. Conclusion: The GIN-ABR method has been extensively utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. Notably, GIN-ABR has several clinical advantages, such as cost-effectiveness, shorter test duration, independence from alertness levels, attention, sleep depth fluctuations, or medication. Additionally, it has shown its compatibility with psychophysical tests. Further research is warranted to explore the impact of various factors on different components of GIN-ABR. Consequently, with its promising findings and growing body of research, the gap in noise test has the potential to be gradually integrated into the set of audiological clinical evaluations.
