Absorption Coefficient Testing can be used for simulation and comparative development of the acoustic absorption performance of materials. While the Absorption Tube is a relatively simple and conventional apparatus used to measure the normal incidence absorption coefficient, there are practical limitations as to the size of test samples and the representation of real world acoustic absorption performance, where there is more sound diffusion. In this case, we use a larger scale test apparatus called a “reverberation room” to conduct our absorption coefficient testing. Testing also involves other apparatus such as the absorption tube.

Engineering Dynamics is equipped with the apparatus to conduct Absorption Coefficient Testing in-house. This helps us develop acoustic products, which enhance the performance of vibration isolation systems. We conduct our testing on systems such as cavity absorbers in isolated floors for gymnasiums.
