Two-Way Cardioid Microphone
In conventional dynamic cardioid microphones a good frequency response and discrimination can be obtained only over a limited frequency range. Through an extensive analogue computer program it was found that it is practically not possible, even with complex acoustic networks, to significantly increase the frequency range. During this research a two-way cardioid microphone system evolved. Data will be presented which indicates that the response and discrimination could be significantly improved over a wide frequency range.
