“…As shown, no significant influence of stimulus frequency on ARL was found in the present study. This finding is in line with the previous study findings (Narayanan, 2017;Prabhu et al, 2015). However, the ARL values have also been reported to be longer at high frequencies (Clemis and Sarno, 1980;Qiu and Stacker, 1998).…”

“…In line with the outcomes of previous studies, an insignificant ear effect was also noted when the ARL results were compared between left and right ears (Narayanan, 2017;Qiu and Stacker, 1998).…”

“…As an effort to obtain reliable acoustic reflex waveforms, the recordings were made at 10 dB above ART. As reported elsewhere, this suprathreshold stimulation level would produce the most optimal contraction of stapedius muscle and waveforms with good morphology (Colletti, 1974;Narayanan, 2017). In particular, we recorded the onset latency of acoustic reflex, i.e., the latency difference between the onset of stimulus and the onset of acoustic reflex (10% of maximum amplitude).…”

“…Nevertheless, as mentioned earlier, the latency features of acoustic reflex have not been extensively studied and require further investigations. In the present study, the acoustic reflex latencies were recorded and calculated according to the recommended protocol (Clemis and Sarno, 1980;Colletti, 1974;Narayanan, 2017;Prabhu et al, 2015). As an effort to obtain reliable acoustic reflex waveforms, the recordings were made at 10 dB above ART.…”

“…This onset measure was chosen as it has been shown to be sensitive in detecting auditory disorders (Clemis and Sarno, 1980;Jerger and Hayes, 1983;Jerger et al, 1978). Other latency measures including late latency (the latency difference between the stimulus onset and 90% of maximum amplitude), initial recovery (the latency difference between the stimulus offset and 90% of maximum amplitude) and terminal recovery (the latency difference between the stimulus offset and 10% of maximum amplitude) have also been reported (Clemis and Sarno, 1980;Jerger and Hayes, 1983;Narayanan, 2017;Prabhu et al, 2015). The mean onset ARL values obtained in the present study are in fact consistent with the previous studies on Caucasian adults (Clemis and Sarno, 1980;Jerger and Hayes, 1983;Narayanan, 2017;Prabhu et al, 2015).…”

Purpose Type 2 diabetes mellitus (T2DM) may induce micro-vascular and macro-vascular changes that can lead to neuropathic changes which may affect the auditory pathway resulting in hearing loss. The study aims to evaluate the outcome of ipsilateral and contralateral acoustic reflex (AR) parameters and reflex decay tests (RDT) in patients with T2DM, and the relationship between average AR parameters, and duration and control of T2DM. Methods An analytical cross-sectional study was conducted in a tertiary care setup in 126 subjects which included 42 subjects with T2DM between 30 and 60 years of age, age-matched with 84 non-diabetic subjects. The subjects were evaluated for pure tone average (PTA), speech identification score (SIS), AR parameters [acoustic reflex threshold (ART), acoustic reflex amplitude (ARA), acoustic reflex latency (ARL)] and RDT. Results The subjects with T2DM showed increased PTA in both ears when compared to the subjects with no disease. No significant difference was found in the SIS between both groups. There was no significant difference in the ART and ARL between the two groups. There was a significant difference in the ipsilateral and contralateral ARA at 500 Hz, 1000 Hz and broadband noise (BBN) when compared between the diabetic and non-diabetic groups. No significant difference was found between average AR parameters and duration and control of T2DM. Conclusion T2DM increases hearing thresholds and reduces ipsilateral and contralateral AR at lower frequencies and BBN. Duration and control of T2DM do not affect the AR parameters.

Background The acoustic stapedius reflex is formed by the contraction of the stapedius muscle in the middle ear cavity when a loud sound is given to both ears. Changes in properties such as the intensity, frequency, duration, and speed of stimulus affect reflex responses. Methods As a result of the literature review conducted between 2005 and 2020, 2846 articles were reviewed and 30 articles evaluating the effects of stimulus changes on acoustic reflex responses were included in the study. Main text In the studies reviewed, it was observed that lower threshold values were obtained by using noise as a stimulus instead of pure sound. Different results were found regarding the duration and frequency of the stimulus. It has been reported that stimulus frequency does not have a significant effect on acoustic reflex delays and the acoustic stapedius reflex threshold increases in the presence of opposite side noise. Conclusion As a result of the studies reviewed, it was seen that the changes in many properties of the stimulus that activate the middle ear muscles affected the reflex response.
