Title:
APPROXIMATION METHOD FOR SOUND CHARACTERISTIC, SIMULATION DEVICE FOR SOUND CHARACTERISTIC, AND PROGRAM
Document Type and Number:
Japanese Patent JP2010145960
Kind Code:
A
Abstract:
To solve a problem that directivity of a speaker can not be simulated easily with small resources and practically sufficient precision.
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.
