Abstract

Noise pollution in the peri-urban region of Bangladesh is a growing environmental concern, having significant adverse effects on human health. In this cross-sectional study, both primary and secondary data were utilized for assessing the level of noise pollution at Patuakhali municipality and assessing the impact on human health. The noise level is measured from 8:00 AM to 8:00 PM at various times. Inverse Distance Weighted (IDW) is also applied to visualize the impacted areas. A semi-structured questionnaire is developed to assess knowledge and perceptions regarding noise exposure and its impacts on health of participants. Results from the analysis indicated that noise levels at the commercial and traffic zones consistently exceeded permissible limits, with the highest level attaining 87.9 dBA in traffic areas. Surprisingly, the silent zones also significantly surpassed permissible limits, particularly during the afternoon and evening. Besides, it is affecting children more than other age groups, as they mentioned that they are frequently having symptoms, such as headaches and sleep disturbance. Conversely, adolescents displayed initial indicators of heart disease. The younger adults exhibited greater vulnerability to long-term consequences, while older adults claimed they were facing high blood pressure and cardiovascular conditions. The self-reported health impacts and noise level have a significant positive correlation (p < 0.001). This study reveals the need for effective noise control strategies and strengthened regulatory bodies to protect public health in rapidly urbanizing municipalities of Bangladesh.
