Single-sensor multispeaker listening with acoustic metamaterials
Abstract
Combining acoustic metamaterials and compressive sensing, we demonstrate here a single-sensor multispeaker listening system that functionally mimics the selective listening and sound separation capabilities of human auditory systems. Different from previous research efforts that generally rely on signal and speech processing techniques to solve the “cocktail party” listening problem, our proposed method is a unique hardware-based approach by exploiting carefully designed acoustic metamaterials. We not only believe that the results of this work are significant for communities of various disciplines that have been pursuing the understanding and engineering of cocktail party listening over the past decades, but also that the system design approach of combining physical layer design and computational sensing will impact on traditional acoustic sensing and imaging modalities.
