A METHOD FOR GENERATING OUTPUT DATA

摘要

A method for generating output data identifying a class of a predetermined plurality of classes. The method comprises receiving data representing an acoustic signal; determining an amplitude of at least one first predetermined frequency component of said acoustic signal; and comparing the amplitude with a respective primary threshold. The method further comprises generating output data identifying one of said classes to which said acoustic signal should be allocated, based upon said comparison. The or each primary threshold is generated from first data representing an acoustic signal representing a first predetermined event, and second data representing an acoustic signal representing a second predetermined event.
