Wastewater Noise Measurements

A wastewater noise measurement system in our laboratory can be useed to measure noise levels from wastewater installations at different water flow rates. Quantities according to EN 14366 can be defined for pipe materials as well as structure bome vibration and sound power levels. Measurements with various types of bracketing, casing and insulation are possible. We also can make precise wasterwater noise calculations for noise modelling purposes.
