Economic growth in urban centers of country is accompanied by increase in environmental degradation mainly in terms of noise pollution. Noise pollution is degrading the quality of outdoor working environment which have detrimental effect due to long term exposure.In present paper a study was carried out to assess the effect of noise on auditory system.Five hospitals in Lucknow city namely King George Medical College, VeeranganaJhalkaribai Women & Child Hospital, DrShayama Prasad Mukherjee Civil Hospital, Balrampur Hospital & Sahara Hospital are monitored for evaluating noise pollution level( Leq) at outdoor locations of outpatient department (OPD) in day time. Using noise pollution level(Leq), Noise Exposure Indicator (NEI) for these hospitals which is a risk based tool for ranking and assessing occupational noise exposure on people present in that environment is worked out. On the basis of NEI, ranking of hospital was found in order from most severe to least severe as King George Medical College, DrShayama Prasad Mukherjee Civil Hospital, VeeranganaJhalkaribai Women & Child Hospital, Sahara Hospital &Balrampur Hospital. Employees working outside OPD were surveyed and a pure tone audiometry test was conducted for evaluating non auditory impact and auditory impact respectively. Survey revealed the prevalence of non-auditory impact namely annoyance, sleeplessness, stress till first period of 1-2 weeks from timing of starting job and impacts get diminishes withlater continuation of job and now employees become susceptible in working in noisy environment .Results of pure tone audiometry revealed absence of noise induced hearing loss (NIHL) but mild hearing loss is observed in King George Medical College due to higher NEI value among the five hospitals.

Hospitals, Employee outside OPD, auditory & non auditory impact, sustainable noise mitigation measures.
