This part of ISO 13472 describes a test method for measuring in situ the sound absorption coefficient of road

surfaces as a function of frequency in the range from to .

Normal incidence is assumed. However, the test method can be applied at oblique incidence although with some

limitations (see annex F) ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
