发明名称 Optimal spatial filtering in the presence of wind in a hearing prosthesis
摘要 The present application discloses methods, systems, and hearing prostheses for reducing wind noise and/or thermal noise in an audio signal transmitted to the user of a hearing prosthesis. A method in accordance with the present disclosure includes utilizing delay-sum beamforming to improve the signal-to-noise ratio in an audio signal that contains wind noise and/or thermal noise. In the presence of at least one of wind noise and thermal noise, amplitudes and phases of at least two input signals are matched. The two signals are then added together, resulting in an average improvement in the signal-to-noise ratio of the signal transmitted to the user of about 3 dB.
