“…Preclinical work based on different animal models has demonstrated that, depending upon the noise characteristics, noise overexposure often leads to cellular damage in the peripheral vestibular system with a well-characterized effect on the response of otolith organs [ 28 , 29 , 30 , 31 ]. Studies using vestibular evoked myogenic potentials (VEMPs) [ 31 , 32 , 33 , 34 ] have provided evidence of the same in individuals with NIHL and in military veterans. Latency shifts, reductions in VEMP amplitudes, increased VEMP thresholds, and absent VEMPs have been shown in NIHL populations with abnormalities correlated to both hearing thresholds and history of noise exposure.…”

Noise-induced hearing loss (NIHL) is the most prevalent occupational disease in the world and firefighters are at increased risk of NIHL due to their frequent exposure to hazardous levels of noise during service. Adverse effects of NIHL include acceleration of age-related hearing loss and an increased risk of cognitive decline. A critical challenge in addressing NIHL is the delayed clinical presentation of symptoms and lack of sensitive tools for early detection. To study the early clinical symptoms of NIHL in this high-risk group, we collected hearing function data including behavioral audiometric thresholds and distortion product otoacoustic emissions (DPOAEs) in 176 firefighters during annual physical assessments. Results revealed significant deficits in cochlear outer hair cell function in the presence of normal audiograms. Additionally, 55% of firefighters self-reported changes in hearing, while 20% self-reported concerns about their balance. This study is the first to characterize DPOAEs in firefighters who display decreased DPOAE amplitudes with increasing years in the fire service. These effects were observed even when controlling for hearing loss and age and are suggestive of a link between hearing loss and occupational exposure to hazardous noise.

“…This was achieved by using body-conducted (BC) stimuli throughout. The incentive to use BC stimuli followed from consideration of safe sound (Mattingly et al, 2015;Asakura & Kamogashira, 2021), raising concerns about the very high air-conducted (AC) stimulus levels required to evoke a VEMP response.…”

The cervical vestibular-evoked myogenic potential (VEMP) was assessed in 24 women and 24 men having a mean age of 19.5 years (SD 0.7). Whilst there was no group difference in VEMP peak to trough (p1-n1) amplitude, VEMP p1-n1 latency was found to be shorter for women than for men by 2.4 ms (95% CI [-0.9, -3.9], chi squared (1) 9.6, p = 0.0020). This equates to 21% of the mean 11.4 ms VEMP p1-n1 latency across women and men. It is a reversal of findings in several prior studies, which are reviewed here. Statistical modelling based on the current study suggests some prior studies were underpowered to detect a sex difference in VEMP latency. Possible causes for sex difference in VEMPs are discussed. Candidate explanations include head resonance, superposition of motor unit action potentials and influence of sex hormones. These explanations are not mutually exclusive, and multiple factors may contribute to difference in VEMP measurement between women and men. This study used a methodology developed in Gattie et al. (2021), which addresses sound exposure concerns with the high amplitude air conducted stimuli necessary to evoke a VEMP response. It is suggested that body conducted stimuli may be preferable for VEMP testing in which ear-specific information is not required.

“…This is a critical aspect in AC VEMP testing, considering the potential cochlear detrimental effect of cumulative repeated loud AC stimuli commonly needed in VEMP (7,8). Anecdotical cases of bilateral hearing loss due to AC VEMP (9,10) have been reported and precautional sound exposure levels have been released (11,12).…”

Introduction A simultaneous recording of cervical and ocular vestibular evoked myogenic potential (sVEMP) to unilateral air-conducted (AC) stimulation reduces the test time and halves the sound load. Materials and Methods The sVEMP has been compared with the conventional sequential unilateral AC cervical and ocular VEMP in a consecutive cohort of 120 subjects attending the vestibular laboratory. The stimulus was a 500-Hz 6-ms tone burst, at 130 dB peSPL for sequential recordings but at 125 dB for the added sVEMP, for cumulative sound load containment. Amplitudes, latencies, and amplitude asymmetry ratios (ARs) were the parameters included in analysis. Results Relevant results were as follows: 1) significantly lower amplitudes in sVEMP versus VEMP (ocular recordings, median = 2.90 [IQR = 0–4.98] vs. 4.15 [1.73–8.98] μV, p < 0.001; cervical, 0.84 [0.30–1.69] vs. 1.36 [0.60–2.30], p < 0.001; electromyography scaled values); 2) 10% lower response rate at cervical recordings and 11% at ocular recordings in sVEMP, particularly in older subjects; 3) significant correlations between cervical amplitudes (r s = 0.88, p < 0.001), ocular amplitudes (r s = 0.71, p < 0.001), peak latencies (r s = 0.36–0.67, p < 0.001), and ARs (ocular, r s = 0.56; cervical, r s = 68, p < 0.001); and 4) good agreement in pathological AR detection (cervical recordings, Cohen’s κ = 0.649, p < 0.001; ocular, κ = 0.589, p < 0.001). Discussion AC sVEMP showed good correlation/agreement with sequential AC VEMP. Test time containment and halved sound load are clinical adds in sVEMP, opening to its use as laboratory standard. However, AC sVEMP presented reduced amplitudes and response rates, secondary to the reduced AC stimulation used in this study to allow checking of the null responses and the pathological ARs at AC sVEMP with conventional AC VEMP.
