The aim of the invention is to control the bass reproduction of audio
signals in electroacoustic transducers based on the psychoacoustic
principle denoted by the term "virtual pitch" or "residual hearing
(hearing of missing fundamental)", in such a way that the perception of
the virtual bass reproduction of the audio signals is improved in
relation to prior art. To this end, the reproduction of the low pitched
frequencies or basses released in the electroacoustic transducer is
controlled by the amplification of the harmonic waves already contained
in the audio signals, in the form of a simulation, in such a way that the
listener experiences or perceives an improved bass reproduction. The
control or simulation can thus be carried out in both a digital manner,
by means of a program module in a digital signal processor of an
electronic appliance for outputting and/or reproducing audio signals
using the electroacoustic transducer, and in an analog manner, by means
of a hardware circuit between a digital analog transducer and a final
amplifier of the electronic appliance for outputting and/or reproducing
audio signals using the electroacoustic transducer.
