Abstract
An acoustic capacity measurement method for finding capacity of a container or object by removing effect of the surface area without using an approximate expression of acoustic impedance is provided. The acoustic capacity measurement method for finding capacity of a container includes a pressure change ratio calculating step, a rotation step, an oblique coordinate transformation step, and a capacity calculating step.
