GB/T 19889.18-2017 specifies a specialized method for measuring the ability of building components (such as roofs, windows, and external walls) to isolate noise generated by raindrop impacts in a laboratory setting. It evaluates the sound insulation performance of components against rain noise by simulating rainfall of varying intensities impacting the surface of the components and measuring the sound pressure level difference between the two sides.
