摘要

Abstract

In this paper, a reflection sound correction formula in semi-reverberation sound field was reasoned out, and then it was tested and verified. First,a reflection sound correction formula was obtained through SPL formula. Furthermore, the reflection sound correction of measuring point was calculated according to this correction formula. Finally,a reflection sound experiment correction was gotten from the difference between one measured value, which was acquired in semi-anechoic chamber, and another measured value, which was acquired in wind tunnel laboratory at the same place. The comparison results show: reflection sound calculated correction and reflection sound experiment correction are well matched,and the correction formula is able to be applied to wind tunnel laboratory. It provides a theory basis for acoustic experiment to calculate reflection sound correction in wind tunnel laboratory.
