Singapore is a very noisy city, but much of the noise pollution can be controlled.
An example of this is the whistle at construction sites and road worksites.
Whistles are given at construction sites to stop traffic along busy roads, to signal heavy vehicles to enter the site, and to guide vehicles in reverse on the main road.
Light batons and lollipop-shaped stop signs should be deployed instead.
The sound of a whistle travels and can affect many nearby residents, office workers and pedestrians.
If you can’t do without whistles, use those whose sound can’t travel that far.
Site managers should modify the protocol for reversing vehicles – they should only whistle when there is danger and the vehicle needs to stop.
Current practice is to whistle several times to let the driver know it is safe to continue backing up.
Whistles are also used to warn workers of the danger zone. White tape should be used to mark off the danger zone, such as when commercial buildings are washed down.
Before the pandemic, whistles were used to guide traffic outside Scotts Square, Lucky Plaza and other crowded intersections. The whistleblowers are gone, but the flow of pedestrians and vehicle traffic in the parking lots is still smooth.
Whistles are now used for traffic control at road works sites in the urban area. Why is this necessary when traffic cops and school traffic cops can safely direct traffic without having to whistle?
Perhaps the use of whistles outside of professional sports should be banned.
