§ Mr. Eldon Griffithsasked the Secretary of State for Defence what tests have been carried out in the vicinity of RAF Honington in Suffolk to establish the level of noise and vibration occurring in the Little Fakenham area as a result of the increased number of Tornado movements at this station; what results were obtained in the summer and what further checks are now being made; by whom the tests are conducted and with what types of instrument; and if, when these tests are complete, he will make a statement.
§ Mr. WigginAn acoustics expert of the environment noise department of the RAF institute of community medicine carried out tests near the airfield at RAF Honington last February using two Brichall accelerometers. The vibration levels were so low that no useful404W results were obtained. Further tests at four properties near the station have been carried out in the past two weeks by experts from the building research establishment at Garston. The data obtained will be analysed using a structural dynamics system to perform a narrow band analysis of the information. Overall vibration levels will be calculated. I shall inform my hon. Friend of the outcome of these tests in due course.
