In natural auditory environments. acoustic signals originate from the temporal superimposition of different sound sources. The problem of inferring individual sources from ambiguous mixtures of sounds is known as blind source decomposition. Experiments on humans have demonstrated that the auditory system can identify sound sources as repeating patterns embedded in the acoustic input. https://www.pomyslnaszycie.com/laguna-3hp-c-flux-cyclone-dust-collector-on-sale/
