Abstract
A sound reproduction apparatus and method enhances a low frequency component in a reproduced sound signal using a reflective sound. The sound reproduction apparatus delays and controls gains of input signals, generates a predetermined number of reflective sound signals to enhance a low frequency component, and outputs a sum of reflective sound signals with the enhanced low frequency component.
