APPROXIMATION METHOD FOR SOUND CHARACTERISTIC, SIMULATION DEVICE FOR SOUND CHARACTERISTIC, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve a problem that directivity of a speaker can not be simulated easily with small resources and practically sufficient precision.;SOLUTION: Sound characteristics by argument are shown by exponential power of function, showing representative directivity of the speaker by including as a variable an argument to a reference line extending from the speaker, and exponents of the exponential power are specified by frequency of a sound output from the speaker to approximate sound characteristics of the speaker by frequency.;COPYRIGHT: (C)2010,JPO&INPIT
