发明名称 Method and system for equalizing a loudspeaker in a room
摘要 Disclosed is a method for equalizing a first loudspeaker positioned in a room in order to compensate for an influence of the room, the method comprising the steps of 1) measuring a listening position transfer function from electrical input of the first loudspeaker to a sound pressure at a listening position in the room, 2) determining a global transfer function representing a spatial average of sound pressure level in the room generated by the first loudspeaker, 3) determining an upper gain limit as a function of frequency, the upper gain limit being based on an inverse of the global transfer function, 4) determining an equalizing filter based on an inverse of the listening position transfer function, wherein a gain of the equalizing filter is limited to a maximum gain in accordance with the upper gain limit, and 5) equalizing the first loudspeaker according to the equalizing filter.
