Abstract

Stable and uniform sound distribution is a key factor in high precise volume determination of solid material especially for mass standards. A numerical study is carried out to study the distribution and uniformity of sound pressure. The FEM simulation results show that the sound pressure distribution gradient of the small chamber is better than large chamber. With the FEM model in this paper, the maximum sound pressure level change is only 0.003 DB (RMS). And also for small chamber, the sound pressure signals are higher and more easily to be acquired for real measuring system.
