Marc A Boillot, John G Harris, Thomas L Reinke, Zaffer S Merchant, Jaime A Borras: Method and apparatus for enhancing loudness of an audio signal. Motorola, Scott M Garrett, February 13, 2007: US07177803 (9 worldwide citation)

Human hearing perceives loudness based on critical bands corresponding to different frequency ranges. As a sound's frequency spectrum increases beyond a critical band into a previously unexcited critical band, the perception is that the sound has increased in loudness. To take advantage of this prin ...
