SYSTEMS AND METHODS FOR NOISE SUPPRESSION Russian patent published in 2023 - IPC G10L21/02 G10K11/16 

FIELD: computer technology for noise suppression.

SUBSTANCE: invention is aimed at increasing of the effect of noise suppression. It is achieved by the first detector, configured to detect the first noise coming to the user along the first sound path, and determine the first noise signal to represent the first noises, the first detector being an air conduction microphone, and the first sound path representing a path with air conduction; a second detector configured to detect second noises perceived by the user and determine a second noise signal to represent the second noises; a processor configured to determine a first noise correction signal and a second noise correction signal, the first noise correction signal being determined based on the first noise signal and the second noise correction signal being determined based on the second noise signal; and a loudspeaker configured to generate sound based on the first noise correction signal and the second noise correction signal, wherein the sound is transmitted to the user via a second sound path different from the first sound path, said loudspeaker being a bone conduction loudspeaker, and the second sound path is a bone conduction path.

EFFECT: increasing of the effect of noise suppression.
