ACOUSTIC DESIGN SUPPORT METHOD

摘要

PROBLEM TO BE SOLVED: To support an acoustic design in a space where a partition wall is present between a sound source and a sound receiving point.SOLUTION: An acoustic design support method of a space in which a sound source room having a sound source and a sound receiving room having a sound receiving point are partitioned by a partition wall preliminarily prepares a relational expression a parameter of which is: articulation in the sound receiving point of sound outputted by the sound source; a sound transmission loss of the partition wall; a background noise level of the sound receiving room; a condition of the sound source; a volume and a surface area of the sound source room and the sound receiving room; an average sound absorption coefficient of the sound source room and the sound receiving room; and a distance between the sound source and the sound receiving point, and obtains the relation between the articulation and a predetermined undefined parameter among the parameters on the basis of the relational expression.
