Description of causes and some effects of sonic booms produced by supersonic aircraft; results of measurements made during demonstration of sonic booms have been used to show that studio roofs having average insulation of 70 db are probably adequate protection against sonic booms of intensities likely to be accepted in urban areas; in some circumstances insulation provided against other aircraft noises may be adequate to exclude sonic booms; actual levels and spectra of noise from subsonic aircraft (including helicopters), as well as distribution of noise levels around major airport, are considered in order to reach specification for sound insulation of roofs to exclude such noise.
