NOISE POLLUTION DEMONSTRATION
Sone unusual machines will be run in the quiet vicinity of the
Central Government Offices tomorrow (Friday).
There will be a compressor, the noise of which in a pneumatic
drill should be familiar, and there will be an instrument to measure the
sound level it produces.
Listening intently will be members of the Noise Pollution Sub-
Committee of the Advisory Committee on Environmental Pollution, whose broad
aim is to look for ways to make Hong Kong a quieter place to live in.
The "noise demonstration" will help them to know the intensity
of a noise both in terms of decibels and as a practical experience.
They will also hear for themselves better ways of running a compressor,
for there is a new model which has a sound reducing devico.
The sound level from this sound-reduced compressor will also bo
measured and compared with the old model.
The Noise Pollution Sub-Committee is chaired by Mr. Henry Litton,
Q.C. Its unofficial members are Mr. John Marden, Mr. Hilton Cheong-Leen, Dr.
Norman Ko Wah Man, Mr. W.M. Sulke, Mr. Geoffrey Yeh and Mr. Carl F. Nielsen.
Its official members come from various government departments concerned
with various aspects of noise pollution.
Note to Editors: You are welcome to send your representatives
to cover the 'noise demonstration'. It will be held
at 4 p.m. at the Central Government Offices East Wing
Carpark.
