Background: Pollution by noise is part of life in rapidly urbanising world. Increased stress, diminishing concentration, anxiety state, insomnia, violent behaviour, cognitive impairment, stress related disorders like diabetes mellitus and hypertension are increased. Noise pollution is found to be a cofactor in all these conditions. Music if properly chosen, can be an important tool to reduce the physiological and psychological adverse effects of noise pollution. Objectives: resent study is to investigate the health impacts of noise pollution, and it also evaluates the efcacy of structured music therapy in such a scenario. Materials And Methods: A randomised control trial was carried out on 103 adult subjects (aged 21–60) residing in high-noise urban zones (average ambient noise >75 dB). The subjects were randomly divided to two groups: Group A (Intervention Group, n=52) received 30 minutes of daily music therapy using the Kinjalk Mode of Music Application (KIMMA), tailored musical compositions, based on circadian rhythms and individual emotional proles. For 6 weeks. Group B (Control Group, n=51)received no intervention with music therapy. Subjects Were Evaluated At Baseline And After 6 Weeks For The Parameters: Ÿ Blood Pressure (systolic and diastolic) Ÿ Salivary cortisol levels Ÿ Pittsburgh Sleep Quality Index (PSQI) Ÿ Perceived Stress Scale (PSS) Ÿ WHOQOL-BREF for quality of life Results: Compared to the control group, Group A showed statistically signicant improvements: Ÿ Mean systolic BP reduced by 8.3 mmHg (p<0.01) Ÿ Mean salivary cortisol decreased by 17% (p<0.01) Ÿ PSQI scores improved by 22% (p<0.05) Ÿ PSS scores decreased by 28% (p<0.01) Ÿ WHOQOL-BREF domains (psychological and physical health) showed a mean increase of 18% (p<0.05) No adverse effects were found. Compliance with music therapy was more than 90%. Conclusion: Noise pollution signicantly impacts mental and cardiovascular health. Music therapy, particularly when personalised and structured as per the KIMMA framework, offers a low-cost, non-invasive, and effective intervention to buffer these adverse effects. This study supports the integration of music therapy in urban mental health and occupational wellness programs.
