N2 - Pervious concrete (PC) is an environmentally-friendly material that exhibits properties such as permeability, water retention, and the ability to serve as a base for vegetation. The purpose of this study is to develop an affordable, straightforward, and rapid measurement technique utilizing mobile devices, such as personal computers (Mac and Windows) and smartphones (Android and iPhone), to evaluate PC’s dynamic elastic modulus. In this study, measurements of the dynamic elastic modulus were conducted on PC specimens with different porosities using these devices. The influence of using these devices with or without external microphones was also examined. The results confirmed that as porosity increased, the dynamic elastic modulus of PC decreased, with the relationship between them exhibiting a linear function. The dynamic elastic moduli were predominantly unaffected by the type of device used or the presence of external microphones. Measurements using mobile devices also showed a very high accuracy, with the standard deviation data and the coefficient of variance being under 0.4 and 4% respectively, for all specimens.
