摘要：This paper studies work exposure for drivers of auto rickshaws in Kolkata, India in a running condition to noise.Since the most negative effects caused by noise exposure are related to the hearing system and it may produce professional deafness or even permanent deafness.It is necessary to assess the noise exposure and to develop mechanisms for studying and proposing preventive solutions for minimizing environmental pollution.Equivalent noise exposures of drivers at work and in-auto noise are evaluated using a precision dosimeter in different areas or locations of various times like summer and rainy seasons etc.Readings were taken in different routes in north Kolkata, India and the noise doses are analyzed.The A-weighted values of Leq (12), L10, L90, TWA (Time weighted Average) and TNI (Traffic Noise Index) are determined.It shows significant effect of noise exposure from auto-rickshaws in Kolkata city of India.
