The new UNE-EN 16272-1:2024 specifies the laboratory method for measuring the sound absorption performance of noise barriers and related devices acting on airborne sound propagation in reverberating conditions.
It also covers the assessment of the intrinsic sound absorption performance of elements which can reasonably be assembled inside the testing facility described in standard UNE-EN ISO 354: 2024 (measurement of sound absorption in a reverberation room).
Among the standards for consultation for its correct implementation are:
-UNE-EN 16272-3-1:2024. Railway applications. Infrastructures. Barreras acústicas y dispositivos relacionados que actúan sobre la propagación aérea del sonido. Método de ensayo para determinar el rendimiento acústico. Part 3-1: Normalized railway noise spectrum and single number ratings for diffuse sound field applications.
-UNE-EN ISO 354:2004. Acústica. Measurement of sound absorption in a reverberation room.
