horn.m is the main program which designs exponential and catenoidal horns. The user inputs the cutoff frequency (Hz) and the throat radius in (meters).horn.m calculates the required length and shape constant of the horn to efficiently radiate at the cutoff frequency. It is assumed that the cutoff...
