Dr Gun (KINGSTON, SOUTH AUSTRALIA) asked the- Minister representing the Minister for Civil Aviation, upon notice:

Can the Minister provide figures on the noise level in areas adjacent to the (a) North East, South West runway at West Beach Airport in each of the last ten years and (b) art estimateof the noise level in those areas in each of the next ten years.


Mr Swartz - The Minister for Civil Aviation has provided the following answer to the honourable member's question:

Noise level measurements for each of the last ten years in areas adjacent to the North East South West runway at Adelaide Airport are not available.

A Noise Exposure Forecast which is a measure of the subjective effect of aircraft noise on the average person has been prepared for Adelaide Airport to cover the years 1975-1980. This forecast, and associated explanatory material, is available from the Regional Director, South AustraliaNorthern Territory Region, and it takes account of such factors as:

(i)   the magnitude and duration of aircraft noise as determined by type, weight and flight profile;

(ii)   the distribution of the noise energy over the spectrum of audible frequencies;

(iii)   the forecast frequency of aircraft movements on various flight paths;' and

(iv)   the distribution of aircraft movements by day and night.

Although aircraft movements over the next ten years are likely to increase at Adelaide airport, and indeed at all other major airports, the availability of quieter aircraft in the future is expected to contain the aircraft noise problem and to make a real contribution to the noise alleviation programme.
