In-Situ Absorption

In-Situ Absorption Microflown offers a complete solution to measure your material properties with the In-situ absorption setup. With a small, hand held impedance gun the acoustic absorption, reflection or impedance can be measured in just a few minutes, broad banded, under normal and oblique angles. This in situ absorption method is a true alternative for [...]
