Acoustics. Measurement of sound absorption properties of road surfaces in situ - Spot method for reflective surfaces1 Scope This part of ISO 13472 specifies a test method for measuring in situ the sound absorption coefficient of road surfaces for the one third octave band frequencies ranging from 250 Hz to 1 600 Hz under normal incidence conditions. For special purposes, the frequency range can be changed by modifying the dimensions of the system. The test method is intended for: a) determination of the sound absorption coefficient of semi dense to dense road
