An acoustic wave is a type of energy that is clean and abundant but almost totally unused
because of its very low density. This study investigates a novel dual‐tube Helmholtz …

High-speed railways have received much attention globally in recent years. While high-
speed railways bring convenience to people, the environmental costs, such as noise …

The quest for intelligent interfaces and seamless human-machine collaboration has driven
the development of acoustoelectric conversion that underpins the sophisticated speech …

Abstract Machine condition monitoring (MCM) plays an important role in reducing failure
losses in the industry. Appropriate wireless sensor nodes (WSNs) used in MCM will allow …

Thermoacoustic engines convert heat energy into high amplitude acoustic waves and
subsequently into electric power. This article provides a review of the four main methods to …

A new concept to enhance efficiency of the acoustic energy harvesting is presented and
experimentally tested in this paper. An auxetic latticed resonator backed by an acoustic …

In this article, a comprehensive review of the computational fluid dynamics (CFD)-based
modeling approach for thermoacoustic energy conversion devices is proposed. Although …
