The GA3205 is a multi-memory hybrid that, with the addition of two microphones, can be used to produce a directional response in any hearing aid. The four available memories can be programmed to include any of the 4 modes of operation: 1 mic omnidirectional, 2 mic omnidirectional, directional, and directional equalized. The variable time delay of the circuit gives it the flexibility to offer a wide range of directivity patterns (ie. cardioid to hypercardioid) for microphone port spacings from 6mm to 13mm. Variable low frequency equalization gives the flexibility to trade-off between bass response and noise performance. |
