FIELD: acoustics.
SUBSTANCE: invention relates to comfortable noise generating devices. Predetermined size buffer is configured, to store CN-parameters for SID (Silence Insertion Descriptor) frames and tightening active frames. Subset selecting device is configured to determine CN-parameters subset relevant for SID-frames, based on stored CN-parameters age and based on residual energies. Comfortable noise control parameters extraction device is configured, in order to use certain subset of CN-parameters for determining of CN control parameters for first SID-frame, following active signal frame.
EFFECT: technical result consists in increase in perceptible sound quality.
