Title:
ACOUSTIC CHARACTERISTIC EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/225681
Kind Code:
A1
Abstract:
This acoustic characteristic evaluation method comprises: a reference sound pressure determining step (S1) of determining, as a reference sound pressure, a sound pressure frequency characteristic, calculated by simulation or measured through a measuring experiment, of a speaker in an anechoic chamber; and a deviation calculating step (S6) of calculating, as an acoustic characteristic evaluation index value, a deviation between a sound pressure to be evaluated and the reference sound pressure, the sound pressure to be evaluated being a sound pressure frequency characteristic, calculated by simulation or measured through a measuring experiment, of the speaker in the anechoic chamber.
