“…This field on the two lines does not attenuate with distance from the source, as noted in general after (12). Our formulae (15) and (16) differ slightly from those in [19] because of a different multiplicative factor in the definition of the upwash. Figure 3 gives contour plots of the pressure field on vertical transverse sectionsx = kā 2 /2 andx = 2kā 2 for Mach number M = kā 2 , because (provided kā > 1) this is the distance at which far-field approximations start to apply.…”

“…a remarkable exact result for a fully three-dimensional problem. The first result of this type was obtained in [12], for a time-domain field, and its single-frequency form is derived in [19]. On the Mach wedge at a given value of z, the acoustic field is influenced only by the leading edge upwash at the same value of z; this explains the proportionality of p(x, y, z, t) to g(z) in (12).…”
