FIELD: information technologies.
SUBSTANCE: method to balance a frequency characteristic of a loudspeaker located in a room includes a stage of a transfer function measurement in a position for listening (L) from an electric input of the first loudspeaker (L1) to a sound pressure in the listening position (LP) in the room, a stage of detection of a general transfer function (G), which represents a spatial average of a sound pressure level in the room developed by the first loudspeaker (L1), a stage to detect the upper gain limit (UGL) as the frequency function. Besides, the upper gain limit (UGL) is based on inversion of the general transfer function (G), a stage to detect a balancing filter (F), based on the transfer function inversion in the listening position (L). Besides, the balancing filter (F) gain is limited by the maximum gain in compliance with the upper gain limit (UGL), and a stage to detect the first loudspeaker (L1) in compliance with the balancing filter (F).
EFFECT: improved quality of received sound reproduction from a loudspeaker in the listening position.
