Space Characteristics of the Microphones in Spherical Sound Wave Field
In this article a practical relationship is shown that gives the connection between the forms of the directional characteristics (cardioid, supercardioid and hyper cardioid) and the parameters of the microphone. An electrodynamic microphone with two acoustical entrances is examined and placed in a field of a spherical sound wave. Shown is the relationship between space characteristics when the microphone is in sphere and planar sound wave. Shown are the basic proportion between the angles Q = 0 and Q = 180 (proportion front - back), as well as when Q = 0 and Q = 90 degrees and their relationship with the microphone parameters when the microphone is in sphere sound wave. Proven is that the form of the directional characteristics in the area of the lower frequencies are a function only of the proportion of the phase angles and the ratio between the distance of the two acoustical entrances and the distance between the microphone and the sound source.
