Acoustics. Measurement of sound insulation in buildings and of building elements - Laboratory measurement of sound generated by rainfall on building elements Ingestion-build-159183 What is ISO 9809‑1 -1 Scope This part of ISO 140 specifies a laboratory method of measurement of the impact sound insulation of roofs, roof ceiling systems and skylights excited by artificial rainfall. The results obtained can be used for assessing the noise to be produced by rainfall on a given building element in the room or space below. The results can also be used to compare rainfall sound insulation capabilities of building elements and to design building elements
