Supplementary to Question No. 10 in the

Legislative Council on 13th March 1985

Mr. Kim CHAM : Sir, as Japan has used the acoustic barriers for some years,

may I enquire when we can expect the examination be completed and implementation

started while residents suffer?

Secretary for Lands and Works :- The Highways Office will be sending a

professional person to Japan to attend a conference. In conjunction with that,

the professional will take the opportunity to study what has been done in

Japan. Meanwhile literature on the subject is being studied, and subject to

the conclusion of the examination, consideration will then be given to the

implementation of this kind of noise abatement measures in circumstances that

would benefit from this kind of treatment.

elevated

Mr. Kim CHAM :- Sir, will priority consideration be given to residential

elevated areas such as the Island Eastern Corridor or the road to the airport

where residents do suffer?

froad

Secretary for Lands and Works :- Yes, consideration will of course be given

to locations where there has been complaints about noise from the elevated

road structure. I do have some theoretical calculations of the degree of noise

abatement possible from the installation of barriers at the Island Eastern

Corridor. To obtain meaningful reduction in the level of noise, the barrier

would have to be from 3 metres high. Even then residents at the higher floor

levels such as floors ten and above do not get the meaningful reduction in

noise level. It is only in the order of one decibel.
