Measurements of sonic-boom intensities made to investigate effects of altitude, flight path angle, Mach number, and atmospheric refraction at cutoff Mach number; effect of Mach number on ground overpressure is small between Mach 1.4 and 2.0; method for estimating effect of flight path angle; comparison of sound pressure levels for fighter and bomber indicated little effect of size or weight at 40,000 ft.
Ground measurements of airplane shock-wave noise at Mach numbers to 2.0 and at altitudes to 60,000 feet
