METHOD FOR TRANSFERRING ACOUSTIC SIGNAL TO USER AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G10K15/00 

FIELD: acoustics, possible use for affecting psycho-physiological state of person during training, in art-therapy, when performing music in concert halls, in theatric and circus performances, during production of movies, during animation of images, etc.

SUBSTANCE: method for transferring acoustic signal to user includes filtration of electric signal, containing information about acoustic signal, and following transformation of electric signal to acoustic signal. Electric signal is preliminarily nonlinearly transformed with non-linearity order not less than 4, during realization of filtration, combination oscillations are selected in range of infrasound frequencies and with amplifier not less than in 2 times these are transformed to acoustic signal, emitted in additional to main signal. Electric signal, carrying information about acoustic signal, may be additionally nonlinearly transformed together with same signal, delayed for not more than 5 seconds. Device for emitting acoustic signal to listener contains electric signal source, containing information about acoustic signal, filtration block, transformer of electric signal to acoustic signal, connected to its output, and also nonlinear transformer and amplifier. Transformation characteristic of nonlinear transformer is described by polynomial of order not less than 4. filtration block is made in infrasound range. Output of signal source is connected to input of nonlinear transformer, output of which is connected to input of filtration block, while output of filtration block is connected to input of transformer of electric signal through amplifier of infrasound oscillations with amplification coefficient not less than 2.

EFFECT: selection of parameters of acoustic images and generation of infrasound accompaniment, taking bio-physical rules of sound perception by listener into consideration.
