<h1>Pavement absorption ISO13472-2:2010 ISO10844</h1> \n<strong>Road Surface Absorption Measurement System</strong> \nMeasure road surface sound absorption in situ in according to ISO 13472-2:2010. \nThe ISO 13472-2:2010 describes the test method for measuring in situ sound absorption coefficient of road surfaces for the one-third octave-band frequencies ranging from 250 Hz to 1800 Hz under normal incidence conditions. For special purposes, the frequency range can be adjusted by modifying the dimensions of the system. \n \n \n \nDownload <a href=https://placidinstruments.com/wp-content/uploads/2020/12/PI_20_PAV_001.pdf>Pavement Absorption</a>
