AB  - Nowadays, small and flat loudspeakers are requested by the market for home and mobile entertainment. One major problem of such small devices is the reproduction of lower frequencies due to physical limitations. A lack of low frequencies has a negative impact on the perceived audio quality. To obtain good audio quality even with small loudspeakers, the utilization of psychoacoustical effects is conceivable. Basic principles of psychoacoustical bandwidth extension, concretely implemented algorithms and parameter set-tings for a considerable extension of bandwidth are explained. Furthermore, a listening test method for evaluating perceived audio quality in comparison to bass extension is described. Based on that, an assessment of increased bandwidth extension and sound coloration is done and a conclusion is drawn.
