Sustainable development has various indicators like transport system, economy, land use etc. Quality of life is one of them and protection from noise, especially at workplace plays a prime role in determining it.Numerous literature surveys have revealed that the construction industry ranks second in terms of thestaff being exposed to loud noise and its consequent hazards. A similar situation was observed in a major infrastructure project in Kolkata, India. A questionnaire survey among the workers and a 3D simulation model was created to assess the noise levels. The results revealed that the perceived noise levels were significantly high and exceeded the limits set by concerned authorities. This warranted actions to reduce noise levels. To achieve this, two alternate simulation models were created with altered acoustic properties. The results of these simulations reduced noise to identical levels, which were lower than the limit set. And hence, it was concluded that lower noise levels could not be achieved and was proposed that adopting either of the two would fit the purpose.
