noise produced on main trunk roads, secondary roads and residential
roads used at peak traffic periods as alternative routes.
The difficulty in measuring road traffic noises arises due
to the rapid fluctuation from 50 dB(A) to 90 + dB(A).
The sound level meter must, therefore, be easy to operate,
simple in design and of robust construction. With these points
in mind two Acos sound level meters complete with calibrators,
extension leads and tripod were purchased A more expensive
meter with press button for the various dB(A) bands and wave
band analysis is possessed by the Department, but has proved
unsatisfactory for road traffic readings Additional equipment
which hasalso proveduseful is acassette tape recorder,although
this is not essential
Looking to the future the acquisition of a chart recorder
would be very useful for continuous monitoring of traffic noise,
Pest Control
Two of our three Pest Control Officers are licensed by the
Ministry of Agriculture, Fisheries and Food in accordance with
Section 10 of the Protection of Birds Act, 1954,to use stupefying
bait for killing or taking wild birds. This enables these officers
to undertake operations against feral pigeons, and once again
particular reference was given to certain British Railways'
property
The baiting of the Council's sewers against rats is dealt
with by the staff of the Borough Engineer & Surveyor, who use
specialist firms for this purpose,
The following is an extract from the Annual Report on
Rats and Mice for the year ending 31st December, 1972, which is
