Scope

This part of GB/T 19889 specifies the laboratory measurement methods for the rain noise insulation performance of building components such as roofs, roof/ceiling systems, and skylights. In this method, rain noise is generated by simulating rainfall to stimulate building components. The results can be used to compare the rain noise insulation performance of different components and to rationally design building components based on the requirements of rain noise insulation performance. The rain noise measured in this part refers to the noise radiated into the interior of the building caused by the vibration of building components due to the impact of raindrops on the roof. The excitation source of the rain noise is simulated rainfall controlled by a water tank, and the lateral sound transmission in the measurement laboratory is suppressed.
