Abstract
The invention provides an apparatus and related method for acoustically improving an environment. In an embodiment of the invention, an apparatus comprises a partitioning means in the form of a curtain for producing a discontinuity in a sound conducting medium, such as air, and for absorbing sound. One or more microphones serve for receiving acoustic energy and for converting it into electrical signals for supply to a digital signal processor. The processor employs an algorithm for analyzing the electrical signals and providing a control signal based on such analysis. In response to the control signal, an electrical output signal is generated and converted into sound.
