In a previous paper, the author has introduced and studied a new algebraic structure which accurately describes the algebra underlying quantity calculus. The present paper is a continuation of that one, which extends the purely algebraic study by add

The ability of the standing wave tube to measure the sound transmission loss of porous materials, which is the subject of the standard ASTM E2611-17, is studied with six porous materials, three of them with open cell porosity, the other three with cl

We measure and analyse the ambient vibration induced in residential buildings in urban settings. While most vibration studies focus on strong, well identified sources, our goal has been the ambient vibration of unidentified sources from the surroundi

We explore the limits of the use of the Kund’s tube and the transfer matrix method for the measurement of transmission loss with common building materials. The results of several tests performed in a standing wave tube with two different building m

We present the results of tests performed in a reverberation room measuring reverberation time with different acoustic absorbent materials in different layouts, compared to those results where the same material was placed as a single piece. With the
