Vizag airport has turned silent, as the officials have decided to do away with announcements, in order to stop noise pollution. Because of the constant announcing of arrivals and departures of the flights, noise pollution in the airport has reached dangerous levels. This will come down once the announcements are stopped, the officials said. Instead of announcements, the arrivals and departures of flights will be displayed on digital boards. Noise pollution could be defeaning and this could even hamper the efficient functioning of the airport staff.
