Abstract

The present invention provides a process (26) for separating a good quality information signal from a noisy acoustic environment (12). The separation process uses a set of a least two spaced-apart transducers (19, 20) to capture noise (13, 15) and information components (14). The transducer signals, which have both a noise and information component, are received into a separation process. The separation process generates one channel that is substantially only noise, and another channel that is a combination of noise and information. An identification process (30) is used to identify which channel has the information component. The noise signal is then used to set process characteristics that are applied to the combination signal to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify information signal. The information signal may be, for example, a speech signal, a seismic signal, a sonar signal, or other acoustic signal.
