“…Such exposure causes successive aggression to the internal structures of the ear, such as the organ of Corti, and leads to noise-induced hearing loss (NIHL) [51–53]. In the present study, the prevalence of NIHL was 18.6% and 22.3% in the left and right ears, respectively, and the most accentuated loss was recorded at the frequency of 4 kHz.…”

Workers in the transportation industry are at greater risk of an incorrect diet and sedentary behavior. The aim of our study was to characterize a population of professional bus drivers with regard to clinical and demographic variables, lipid profile, and the presence of cardiovascular risk factors. Data from 659 interstate bus drivers collected retrospectively, including anthropometric characteristics, systolic and diastolic blood pressure, lipid profile, fasting blood glucose, meatoscopy, and audiometry. All participants were male, with a mean age of 41.7 ± 6.9 years, weight of 81.4 ± 3.3 kg, and BMI 27.2 ± 3.3 Kg/m2; the mean abdominal and neck circumferences were 94.4 ± 8.6 cm and 38.9 ± 2.2 cm; 38.2% of the sample was considered hypertensive; mean HDL cholesterol was 47.9 ± 9.5 mg/dL, mean triglyceride level was 146.3 ± 87.9 mg/dL, and fasting glucose was above 100 mg/dL in 249 subjects (39.1%). Drivers exhibited reduced audiometric hearing at 4–8 kHz, being all sensorineural hearing loss. The clinical characterization of a young male population of interstate bus drivers revealed a high frequency of cardiovascular risk factors, as obesity, hypertension, hyperlipidemia, and hyperglycemia, as well as contributing functional characteristics, such as a low-intensity activity, sedentary behavior, long duration in a sitting position, and high-calorie diet, which lead to excessive weight gain and associated comorbidities.

“…Berjis et al also reported that at 2000 Hz, left ear hearing threshold was significantly higher than that of the right ear among Heavy Goods Vehicle (HGV) drivers ( Berjis et al, 2011 ). Additionally, some studies have found prevalence of hearing loss among drivers from 18.1% to 55.4% ( Janghorbani et al, 2009 , Santos & Castro Júnior, 2009 ).…”

Objective:This study aims to investigate loss of hearing among drivers in Zahedan, southeastern Iran.Patients and Methods:This study carried out on a total of 1836 drivers in Zahedan in 2013. Loss of hearing in both ears was measured at 250, 1000, 2000, 3000, 4000, 6000, and 8000 Hertz. The demographic variables, blood parameter and anthropometric data were recorded through interview and examinations. Data were analyzed in Stata.12 software using paired t-tests, McNemar test and Multiple Logistic Regression.Results:The mean age was 38.2±9.8 years. The highest mean hearing thresholds in the right and left ears were 25.7±9.1 and 27.7±9.1, respectively at 250 Hz. There was significant difference between left and right ears hearing threshold at all frequencies (P<0.001), and the highest difference occurred at 250 Hz. Hearing threshold in the left ear was greater than in the right ear at all frequencies. Hearing threshold was correlated to marital status, type of license, and vehicle, smoking, age, and driving history at all frequencies (P<0.01), and also significantly correlated to blood sugar and cholesterol levels at 250 and 500 Hz in both left and right ears (P<0.01).Conclusion:In conclusion, high levels of noise increase hearing threshold with greatest damage to the left ear. Therefore, drivers should be periodically examined for ear damage in accordance to variables affecting loss of hearing. Moreover, drivers must be educated about usage of appropriate ear-plugs during driving, especially for the left ear.

“…These findings led them to conclusion that along with cochlear damage neuronal pathways in brainstem were also involved. [15,17,18] Differences between previous studies and present one may be due differences in selection of cases. In the present study, we selected cases with duration of exposure to noise with more than 1 year, whereas previous studies selected cases with more than 5 years exposure to noise.…”

Brainstem evoked response in bus drivers with noise-induced hearing loss

Abstract: in the NIHL group, besides sensorial injury, changes in BEAP latencies suggest an early functional injury of the first auditory pathway afferent neuron.
