HC Deb 23 November 1987 vol 123 cc33-4W
Mrs. Margaret Ewing

To ask the Secretary of State for Defence what research is being undertaken to establish whether 70dB 12 hr LAeq contours can include noise levels from static aircraft prior to take-off.

Mr. Freeman

No research is required. The LAeq index takes into account all noise from aircraft operations, including the noise emitted by static aircraft prior to take-off.

Mrs. Margaret Ewing

To ask the Secretary of State for Defence if he will publish in theOfficial Report the total amount of grant awarded to date by his Department to residents in the vicinity of Royal Air Force, Lossiemouth who have been eligible for sound insulation grants.

Mr. Freeman

To date, some £39,000 has been paid in grants under the noise insulation grant scheme at RAF Lossiemouth.

Mrs. Margaret Ewing

To ask the Secretary of State for Defence if he will publish in theOfficial Report details of the nature of the survey to be undertaken by the Royal Air Force Institute of Community and Occupational Medicine at Royal Air Force, Lossiemouth early in 1988; and whether there will be any changes in procedures from those used in previous surveys.

Mr. Freeman

The aim of the noise survey will be to check the position of the average 70dB(A) noise contour in relation to Lossiemouth town. To this end, six measurement sites in the town have been chosen and agreed with Moray district council. The only change in procedures is that the microphones will be placed on masts well above the ground to avoid noise reflection and shielding from buildings.
