A Highly Directive 2-Capsule Based Microphone

Document Thumbnail

While microphone technology has reached a high level of performance in terms of signal-to-noise ratio and linearity, directivity of commonly used first order microphones is limited. Higher order gradient based microphones can achieve higher directivity but suffer from signal-to-noise ratio issues. The usefulness of beamforming techniques with multiple capsules is limited due to high cost (a high number of capsules is required for high directivity) and highly frequency variant directional response. A highly directive 2-capsule based microphone system is proposed, using two cardioid capsules. Time-frequency processing is applied to the corresponding two signals. A highly directive directional response is achieved which is time invariant and frequency invariant over a large frequency range.
