概要
- 論文の詳細を見る
An acoustic impedance measurement technique based on the open-short method is developed. This method allows the impedance of a sample placed in a capsule to be measured, using a fused quartz rod as a transmission line. The interference patterns are measured using an air backing while varying the gap between the end of the transmission line and the surface of the capsule, and the measurements are then repeated using a tungsten backing. The acoustic impedance of salt water calculated by this method was within an error margin of 10%.
