It is important that we take a serious view of the noise pollution of the subway/MRT that will cause health problem in the long term.
In 2011 GE, while my team was contesting in Tampines, we have raised the issue of health hazard due to the close proximity of the MRT rail built next to the various HDB flats, especially those in Tampines.
After the GE, SMRT started their so call "noise barrier" experiment but is it effective? Is it the right kinds of Sound barriers needed to reduce the noise from the track sufficiently?
I present my photo essay here on the inadequacy of MRT's "noise barriers"
I have put up an example of how Hong Kong MTR design their Sound barrier as compared to Singapore SMRT.
This photo shows the MTR system in Hong Kong. Arrow A points to the Covered Sound Barrier which it has built when the track is built close to the flat.
Arrow B is the strain station which is build underneath the housing estate, noise completely blocked from above.
This is the most effective Sound barrier.
This is the Sound Barrier built by Singapore SMRT. Observe how close the track is built next to the HDB flat. But the sound barrier is really pathetic.
First, unlike the HK sound barrier, it did not cover the whole track from top to bottom. Secondly, it is not even high enough to be effective! This is because sound will bouce off from the train and it will bounce off towards the flat.
At the very least, the Sound Barrier has to be as high as the train itself! It is a sloppy ineffective design.
It is a common sight that MRT tracks cut through HDB estates with BOTH sides populated with HDB flats.
We do not know how many such Sound Barriers have been built as they have promised.MRT has just quietly stop mentioning about their ineffective Sound Barrier experiment altogether!
It is surprisng that even those who live in private condominiums suffered the same fate but yet, they didn't make noise or demand for proper Sound Barriers to be built!
The issue of building effective Sound Barriers to MRT tracks as well as Expressway is NOT new. I have raised it several times in this blog since 2004.
