In situ sound absorption estimation with the discrete complex image source method
Eric Brandao, William Fonseca, Paulo Mareze +4
Estimating the sound absorption in situ relies on accurately describing the measured sound field. Evidence suggests that modeling the reflection of impinging spherical waves is imp…
