Comprehensive Study on Precision and Accuracy of In-Lab and On-Site Measurement of Pavement Acoustic Absorption
As is well known, pavement features affect traffic noise. In more detail, rolling noise depends on generation factors and acoustic absorption. This latter can be assessed through in-lab (ISO 10534-2) and/or on-site (ISO 13472-1; ISO 13472-2) tests but several issues arise when comparing measures carried out according to different measurement methods. Consequently, the objectives and scope of the study described in this paper were to compare different methods to assess the acoustic properties of a pavement in order to derive information to use in practical applications. The following devices were used: in-lab Kundt tube; on-site Kundt tube; Adrienne device. Based on measurements, absorption spectra were derived. Analyses and results focused also on composite indicators, first-pick frequencies and objective functions. In-lab Kundt tube emerges as a device quite precise and accurate while on-site Kundt tube and Adrienne device prove to have great potential. Outcomes can benefit both practitioners and researchers. Future research will address a number of issues that arose during experiments and analyses in the pursuit of a better understanding of phenomena and reasons which emerged from the study.
