Abstract Deep learning and Neural Networks strategies have become very popular in the
last year as tools for image and data processing. As for acoustics, neural network-based …

In this work, a new grid-free global optimization algorithm that combined the image source
model (ISM) and state transition algorithm (STA) was proposed to realize the sound source …

Recently several equivalent source method (ESM) based near field acoustic holography
(NAH) methods have been proposed based on compressive sensing, such as one norm …

Effective direct control of the sound source is the fundamental solution to the problem of
noise. Herein, we propose a passive, non-closed and remote scheme for omnidirectional …

Three-dimensional acoustic imaging with microphone arrays is a challenging task due to the
numerous degrees of freedom of the physical processes at stake. Instead of meshing a …

An outdoor heating, ventilating, and air conditioning (HVAC) unit has multiple noise sources
which contribute to its overall acoustical signature, such as fan blade passage noise …

Outdoor heating, ventilating, and air-conditioning (HVAC) units emit a significant amount of
noise, which may lead to poor sound quality and a perceived low product quality. It is the job …

Source identification in a complex environment has a remarkable interest in acoustic and
noise-engineering as well as in defence applications. The detection of mobile sources …
