Abstract This paper discusses a novel, compact sound absorption solution with high performance at various frequencies, including low achieved through the effective use of Computational Design and Additive Manufacturing (AM). Sound is widely applied for reducing noise improving room acoustics; however, it often constrained by conventional design, material properties production techniques, which ...

Measurements of acoustic properties sound absorbing materials in impedance tubes show poor reproducibility, which was demonstrated round robin tests. The tube measurements are standardized but lack precise definitions the actual measurement setup, specimen preparation, and other factors that introduce uncertainty practice. In this paper, machine learning models identify those mostly affect abso...

Speech acoustics vary due to differences in age, gender, vocal tract length, microphone, and so on. The authors recently proposed a structural and abstract representation of speech, where these variations were effectively removed. This representation captures only dynamics of speech. In our previous study, using this abstract representation, a new framework of speech synthesis was proposed and ...

The aim of this work is to identify the physical processes that occur in the network and contribute to its dynamics and heating. We model the network as consisting of individual flux tubes with a non-potential field structure that are located in intergranular lanes. With a typical horizontal size of 200 km at the base of the photosphere, they expand upward and merge with their neighbors at a he...
