Abstract

This study examines the non-auditory effects of noise pollution on the attentional, social, and emotional aspects of street vendors and traffic police who have been exposed to noise for more than 5 years. The study group consisted of 25 traffic police and 25 street vendors aged 22 to 55 years, with no history of hearing loss, middle ear pathologies, or other neurological problems affecting hearing. A checklist consisting of 20 questions was used to collect data, exploring the social, emotional, and attentional dimensions. The study aims to provide insights into the potential impact of noise pollution on these dimensions, especially in individuals with prolonged noise exposure. The study aimed to investigate the prevalence of noise-induced hyperacusis in two groups of individuals who have been exposed to high levels of noise for more than five years: traffic police and street vendors using a checklist. Mann-Whitney U test was used to compare the scores obtained in each domain for the two categories, and the results indicated that there were no statistically significant differences between the scores of major subscales. This means that the scores for social, emotional, and attentional aspects of hyperacusis did not differ significantly between street vendors and traffic police. The study highlights the importance of identifying the specific ways in which noise pollution affects individuals, to develop more targeted interventions to reduce the impact of noise pollution on communities. However, the study has some limitations, including the small sample size and the limited duration of noise exposure. Future research should include larger sample sizes, compare different professions that work in noisy environments, and include subjects with more than 5 years of working experience to better understand the impact of prolonged noise exposure. Additionally, more samples for normalization can be included in future studies to reduce the chances of sampling errors and to improve the generalizability of the findings. Overall, the study provides important insights into the impact of noise pollution on the attentional, social, and emotional dimensions of street vendors and traffic police, and further research is needed to fully understand the impact of noise pollution on human health and well-being.
