Ineffective MRT Sound Barriers

In land scarce cities like Singapore and Hong Kong, it is inevitable that we will have to build our rail system in extremely close proximity to our housing estates or flats.

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.
 

Look at the whole straetch of rail sitting next to the flats but no Sound Barriers built.

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.

    But why would PAP want to build effective sound barriers when they could win elections and by elections anyway?

    If I were PAP, perhaps I will build a sound barrier to show that PAP care for Sinkies well being but whether it is effective or not, it is Sinkies die their business.

    The comment by Mr Goh Meng Seng is misleading. The structure pointed out as noise barrier is obviously a MRT station. There are building beyond the station and there is no sound barrier.

    Being a human being and being human. Most or not all are just a transit for paycheck in a job. The approval that there were no emergency back doors for fire emergencies.........The approval that people are living like fishes with hardly any concrete but overtook by full glass where curtains were mainly shut............................Motto, We wash our hands, up to you how you want to wash yours............Damn funny.

    It’s important to realize that whenever you give POWER to politicians or bureaucrats, it will be used for what they want, not for what you want. Harry Browne

    Our founding father Harry Lee and his team of first generation leaders grew today's Singapore from a tiny backwater without the benefit of GST, COEs, capital gains tax, you name it tax etc. etc, rather strange that now all these taxes, levies blah blah are deemed necessary. Harry and his old team hearts were a better life for the people rather than exploitations for $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.

    And may I add about today:-)

    As long as it fits their agenda.

    Keep fuelling themselves with we know best, one day will run out of gas.
