“…[19][20][21][22] A systematic trend of decreased wave I amplitude with increasing noise exposure backgrounds (NEB) was observed by Stamper and Johnson in 2015. 23 In patients with NIHL, many authors have observed a significant extension of the waves I, III, V and I-III inter-peak latencies, 17,24 with results similar to that of the present study. They concluded that, besides the cochlear damage, there are damages to the neural synapses of the hair cells and the neural fibers of the cochlear nerve.…”

“…27 Few studies in patients with NIHL have shown a significant prolongation of the latency of wave V with IPL I-V prolongation. 24 In the present study, we did not observe a significant change in these latencies. Differences between results of the previous studies and the present one may be due to differences in selection of cases.…”

“…The associated problems like back pain, and irritation do not show a significant difference while hearing loss was significantly different (p < 0.01) between bus and truck drivers (Table 2). Previous literature demonstrated that urban bus drivers are under high risk of noise induced hearing loss (Lopes et al, 2012;Santos and Junior, 2009;Fernandes et al, 2005Fernandes et al, , 2001Silva and Mendes, 2005).…”

The purpose of this study was to find out the vulnerability of bus and truck drivers due to constant exposure of vehicle-engine noise inside the vehicle cabin. Comparative results revealed that noise levels inside the cabin of buses and trucks were in the range of 88.6-102.4 dB and 87.95-103.4 dB, respectively. The health status of bus and truck drivers was assessed by measuring their systolic and diastolic pressure, pulse rate, BMI, digestion problem, hearing loss, vision problem, back pain and irritation. Paired t-test of the results revealed non-significant (p < 0.05) relation between systolic and diastolic pressure of both bus and truck drivers. The pulse rate of truck driver was significantly (p < 0.01) related with noise level inside the cabin of truck. The humidity level inside the cabin showed a positive relation with vehicle age (p < 0.01) and driving period (p < 0.01). This study clearly suggests that vehicle engine noise adversely affects the cardiovascular health of both bus and truck drivers.

“…The association between noise exposure and the abnormal latency of wave V was unexpected: literature suggests that noise exposure lesions might alter the latency of wave I [Santos;Castro Junior, 2009], due to cochlear lesions [Jerger and Jerger, 1989]. In this sample, patients with this outcome were exposed to noise and were infected with SARS-CoV-2.…”

Introduction: The aim of the study was to describe auditory and vestibular findings in Brazilian adults after COVID-19 in a municipality from the outskirts of the São Paulo state. Methods: This was a transversal and exploratory study comprising sixteen participants infected by the SARS-CoV-2 virus, confirmed through RT-PCR detection, aged 20 to 55 years. Subjects underwent anamnesis, vestibular and auditory testing. Fisher’s exact test was used to evaluate medication use, chemical and physical exposure, and occupational risk and McNemar test was used to compare auditory and vestibular symptoms pre- and post-COVID-19. Results: Most patients were women (75%) and had been exposed to the virus over 90 days before testing (50%). 18.8% used hydroxychloroquine, 68.8% used ivermectin, and 87.5% used azithromycin to treat COVID-19. Auditory complaints were reported by 31.2% and vestibular by 18.7%. There was no statistical difference before and after the disease. Other reported symptomatology was hair loss, pain, fatigue, memory loss, difficulty to concentrate, and headache. Auditory findings were relevant in contralateral acoustic reflex, in the distortion-product otoacoustic emissions, and in the brainstem auditory evoked potential, characterizing a neurosensorial compromise. 43.74% of patients had altered vectonystagmography. When comparing both ears, no statistical relevance was found; however, when results were crossed with medication use and exposures, there was statistical relevance in the amplitude of the V wave for medications and absolute latency of the V wave to exposure to physical agents. Discussion/Conclusion: This study demonstrated auditory and vestibular findings of neurosensorial nature, considering hearing and of a peripheral vestibulopathy. As it is a study of transversal nature, it is not possible to extend results to general population; yet it may be a finding to future studies.
