"WebAug 12, 2005 · The Rayleigh distance D = ka 2 /2, where k = 2πf/c, f is the frequency, c is the sound speed, and a is half the largest dimension, has been used to approximate the size of the geometric nearfield of plane radiators. We found that, for variously shaped radiators, the Rayleigh distance is useful in approximating the geometric nearfield size. " - Rayleigh distance
