The Chhatrapati Shivaji International Airport (CSIA) in Mumbai, India, is reportedly testing and commissioning noise mapping measures under a civil aviation requirement (CAR) issued by Directorate General of Civil Aviation (DGCA) to reduce noise concerns in areas around airports.
The DGCA issued the CAR mandate to enclose noise around airports, while mandating noise mapping.
Airports are also required to carry out a noise mapping assessment around them, including the areas directly in the flight paths, an evaluation of the existing noise loads and the population affected, and ultimately build up a noise management action scheme.
Indian Express cited an undisclosed spokesperson as saying: "CSIA will assess the existing noise loads due to aircraft operations within the airport, as well as background noise, and the reports on the various noise metrics will be submitted to the DGCA according to the requirements.
"At CSIA, there are noise monitoring terminals installed in the flight path of the main runway and MIAL monitors aircraft noise, as well as background noise."
Since the previous week, the airport has been put on high alert upon discovery of an ISIS threat message scrawled on a wall of a washroom on the airport premises.
The Central Industrial Security Force (CISF) has bolstered security within the premises and has been executing elaborate checks outside the premises.
