In this lab two 4000 liter tanks are used to create the gas flow. The flow noise laboratory equipment layout is arranged according to ISA-S75.07-1997 standard for noise measurement.

In this laboratory, the hydro/aerodynamic performance of valves, especially their discharge coefficient, can be examined.

The gas flow rate is calculated according to EN ISO 5167-2.

Impedance Tube: Measurements of the impedance and absorption coefficient of the materials are carried out according to ASTM E1050-08 and ISO 10534-2 using a tube, two microphones and a frequency analysis system.
