NOISE TEST BENCH

Measurement of the noise produced by taps and hydraulic appliances used in water distribution plants.
This test bench is used for R&D of sanitary taps, valves and hydraulic components or to compare different products. The test rig is designed in compliance with EN ISO 3822 standard, the noise is measured by using a specific microphone inserted into the pipe, so it is possible to carry out the measurement of the noise produced by taps and hydraulic appliances used in water distribution plants.
This method is in compliance with EN ISO 3822 Standard and avoids the construction of an anechoic room. It is possible to operate in laboratory because the ambient background noise doesn’t influence the measure.
The bench can’t be used for official measures.
