Abstract
About 10 years ago at an ISO TC 29 meeting, the concept of the measurement of rainfall noise was suggested. At the time it made no sense to me. Who cares about this? Not me, since I liked the sound of rain on my roof, and the louder the better. The concept was to evaluate roofs to assess the insulation capabilities from sound (vibration?) produced by rainfall. But in spite of my skepticism, wiser heads prevailed, and in the end, the approach was drafted into a work item, a draft, and a final draft standard. This paper is a summary of ISO FDIS 140‐18, ‘‘Acoustics—Measurement of sound insulation in buildings and of building elements—part 18: Laboratory measurement of sound generated by rainfall on building elements.’’ I discuss the equipment needed, the test method, and the uncertainty.
