Dear Qitai,
Since you say I didn't answer your question, I will do it
now.
If you want to have a detailed study on this, there are alot on the
internet. I have just given a very good link in my response to some
misleading information. These are done by academics in Hong Kong,
with regard to the effectiveness of noise barriers, using different
materials. However, if you are asking me to do a study in
Singapore, please lah, this is the govt's job! I don't pretend to
be the govt when I am not! Unless the govt is willing commission a
study on this, fund this project, then I may do my best helping
with the study, even though I am not a trained engineer, I think I
could contribute. That's what govt is for! To provide "public
goods" such as infrastrucutres and such. One must understand the
role of govt before we expect everyone to become govt.
If the workings of a government is based on "complains" from
Singaporeans, then that's very sad. That's the would be the most
ineffective govt. For problems we cannot see, we depend on
feedbacks. For problems we spot, we solve it through our own
initiatvies. Simple as that.
The most common misconceptions of Singaporeans are that when they
vote for anyone, they expect them to be expert in everything; for
opposition, they expect them to become govt! Hey, the whole govt is
run by civil service! That's what parliamentary democracy is all
about! Those ministers are decision makers, giving directions BASED
ON whatever information the civil servants provide them! They do
not necessary know every bolts and knots of the ministry!
You may not be affected by such noise level, but there is a simple
way you could find out whether it is acceptable to you. Goto AMK
MRT station, walk to blk 50X, sit down there for a couple of hours
in the afternoon. OR just take a look at your street directory.
Look for the block built in Simei which is just next to the
highway. Visit that place, sit down there.
PAP has many resources to do their own research. We don't. But
empathy is what I have because I am more aware of my surroundings,
more aware of the problems my fellow Singaporeans face which most
of the time, they prefer to suffer in silence.
