HC Deb 06 April 1967 vol 744 c86W
Mr. Elystan Morgan

asked the Minister of Technology what tests have to date been held in the United Kingdom in simulated conditions to determine the approximate loudness of sonic bangs which will be caused by the flights of Concord over the United Kingdom on its routes between Europe and North America.

Mr. Stonehouse

None of the nature indicated. But research into a number of methods of sonic bang simulation is continuing.
