“…Bilateral and symmetrical hearing loss in traffic policemen with chronic noise exposure was reported in the study by Indora et al . [ 24 ] The study by Tikriwal et al . [ 35 ] among carpet workers observed a high prevalence of both tinnitus and hearing loss, with increasing prevalence associated with the greater severity of hearing loss.…”

Background: India has over 50 million workers employed in industries with exposure to very high sound levels, predisposing them to noise-induced hearing loss (NIHL). Methods: We conducted a systematic review and meta-analysis by using the following criteria: (1) Observational or experimental studies conducted in India; (2) English language studies; (3) Published during January 2010–December 2019; (4) Primary outcome: proportion of participants detected with NIHL. We reviewed bibliographic databases (PubMed, Scopus, and DOAJ) and Google Scholar, and extracted the relevant data. Results: A total of 160 documents were identified after removing duplicates, and 33 full texts were screened, of which 22 studies were included. The mean (SD) effective sample size of the studies was 107.1 (78.9). The pooled proportion of participants with NIHL irrespective of the category was 0.49 (95%CI: 0.22–0.76) and that of hearing loss was 0.53 (95%CI: 0.28– 0.78). Most studies reported that none of the workers, especially in the informal sectors, used auditory protection. Conclusions: NIHL is a major neglected public health occupational health challenge in India linked with adverse social determinants of health. Sustained advocacy for implementation of legislative and behavior change communication for protecting the hearing of workers is warranted.

“…Earlier, we observed a conduction delay in the peripheral part of the auditory pathway in traffic policemen. [7] In addition to traffic noise, various other factors such as lack of awareness of protective measures and duration of exposure for more than the allotted hours may have contributed to the development of hearing impairment in them. Similarly, alteration in brainstem auditory evoked response indicating altered auditory conduction up to the level of the brainstem with no significant change in MLR and P300 response was observed in subjects exposed to noise at Mumbai Airport.…”

“…We have evaluated the possibility of deficits in auditory pathways in traffic policemen previously by means of brainstem evoked response audiometry, midlatency response (MLR) and slow vertex response. [7] Delayed conduction in the peripheral part of the auditory pathway was observed, while conduction was intact at the subcortical and cortical level.…”

Objectives: Occupational exposure to environmental factors has various adverse effects on health. The traffic policemen are exposed to the higher health risk as they are constantly working in the noisy and polluted environment. Since the job of traffic policemen demands concentration and attention, we planned to study event-related potentials (ERPs) in them to assess this aspect of their cognitive ability. Materials and Methods: The present study was conducted on 35 traffic police personnel from the area of East Delhi who were posted at busy traffic intersections for more than 3 years. ERPs were recorded using the oddball paradigm. They had to respond to target stimuli by pressing a button on the response pad with a thumb of their dominant hand. Results: The latencies of N100, P200, N200, and P300 waves were not significantly different between controls and subjects. P300 latency was 266.41 ± 39.21 in controls and 254.20 ± 30.84 in subjects (P = 0.15). P300 amplitude was also not significantly different in both groups. Conclusion: There are no changes in the latencies of different components of ERP’s of traffic policemen, indicating preserved concentration and attention in our study.

“…Several studies have found a link between the length of hazardous noise exposure at work and the degree of hearing loss in workers [16,[36][37][38]. Indora et al discovered bilateral and symmetrical hearing loss in traffic cops exposed to chronic noise [17]. They discovered that chronic noise exposure resulted in delayed conduction in the peripheral part of the auditory pathway, ie, auditory nerve up to the level of the superior olivary nucleus; no impairment was observed at the level of sub-cortical, cortical, or association areas.…”

The term "noise-induced hearing loss" (NIHL) refers to sensorineural hearing loss brought on by either acute acoustic trauma or prolonged exposure to loud noises. Noise exposure has the potential to permanently change the hearing threshold due to irreparable damage to the inner ear. Many risk factors affect the incidence of NIHL including personal factors; such as genetic factors, age, sex, and lifestyle; and elements relating to the noise; such as the length of exposure, its volume, and frequency. This study aims to explore the updated evidence concerning the causes, risk factors, diagnosis, and management of Noise Induced Hearing Loss that were carried out worldwide. The following databases were searched: PubMed, Web of Science, Science Direct, EBSCO, and the Cochrane Library. Using Rayyan QCRI, study papers were screened by title and abstract before being subjected to a full-text evaluation. Eleven research studies with participants of different ages and sexes appropriate to NIHL were included in this review and the relation between different variables with NIHL was discussed. NIHL is a significant problem, especially among industry workers with a high risk of noise exposure. The primary risk factors for NIHL are noise exposure type, intensity, and duration. Smoking and alcohol consumption also significantly affect hearing performance.
