METHOD FOR INSPECTING LISTENING POSITION, LISTENING POSITION INSPECTION SYSTEM AND LOUDSPEAKER APPARATUS TO BE USED FOR THE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a listening position inspection method, a listening position inspection system and a loudspeaker apparatus to be used for the system, in which the deviation between a reference listening position to which sounds are outputted from respective loudspeakers and a practical listener's listening position can be inspected in an error-reduced state.;SOLUTION: The listening position inspection method comprises a step for arranging a microphone 3a on a position p2 where a listener listens sounds from a plurality of loudspeakers su1, su8; a step for inputting an inspecting sound signal of a prescribed pulse width to the plurality of loudspeakers su1, su8 by fixed frequency at set timing that sounds from the plurality of loudspeakers su1, su8 simultaneously arrive at a reference listening position; and a step for comparing the pulse width of a synthesized sound signal received by the microphone 3a and received from the plurality of loudspeakers su1, su8 with the pulse width of the inspecting sound signal and detecting a deviation between the position of the microphone 3a and the reference listening position according to this comparison.;COPYRIGHT: (C)2007,JPO&INPIT
