ISO 140 - 5 On - Site Testing of Airborne Sound Insulation Value
With this test, the sound reduction value of a façade element is measured. Sources distanced 5 metres from the façade create a stable field of sound between 50 and 5000 Hz, and after the receptors measure the echoes, a final average sound absorption value is calculated.
