First Claim
Patent Images
1. A method that enhances communication in a noisy environment comprising:
- receiving input signals from two input arrays, where each of the input arrays comprises two receivers;
processing the input signals, including obtaining a wanted signal by a wanted signal beamformer and obtaining a blocking signal by a blocking beamformer; and
selecting, based at least on the processed input signals, at least one loudspeaker out of at least two loudspeakers on which the processed input signals are to be output.

Abstract
A communication system enhances communications in a noisy environment. Multiple input arrays convert a voiced or unvoiced signal into an analog signal. A converter receives the analog signal and generates digital signals. A digital signal processor determines temporal and spatial information from the digital signals. The processed signals are then converted to audible sound.
