Unique Directional Properties of Dual-Diaphragm Microphones
Dual-diaphragm condenser capsules are commonly used in popular multipattern microphones as well as in some single-pattern unidirectional designs. These capsules react much differently to sound sources than single-diaphragm capsules in the frequency range of up to approximately 1 kHz. As a method of developing intuition, frequency response and directionality as a function of distance from the sound source were demonstrated using a simple model. Pop sensitivity and multipattern operation were also investigated. Comparisons and conclusions are validated with measurements made on physical microphones.:
