ENERGY BAND METHOD FOR PROCESSING ACOUSTIC DATA

Abstract: a method that includes obtaining a first acoustic signal and transforming the first acoustic signal into a first frequency spectrum using a frequency transformer, where the first frequency spectrum comprises a first plurality of frequency data points. the method further includes partitioning the first plurality of frequency data points into a first plurality of energy bands using an energy band partitioning function. the method further includes determining a representative frequency for each of the first plurality of energy bands and determining a representative amplitude for each of the first plurality of energy bands, where the representative amplitude is determined based on an energy conservation principle. the method further includes determining a first energy band series, where the first energy band series comprises the representative amplitude and the representative frequency for each of the first plurality of energy bands and determining, using the first energy band series, an acoustic signal characteristic.
