An Acoustic Modelling Based Remote Error Sensing Approach for Quiet Zone Generation in a Noisy Environment
TL;DR: An improved approach to increase the effective frequency range based on the acoustic modelling is presented and the proposed method can provide more than 20 dB noise reduction up to 1650 Hz for a quiet zone with a radius of 0.1 m by using only three microphones under the studied situations.

A Novel Outlier Detection Model for Vibration Signals Using Transformer Networks
TL;DR: In this paper, a transformer-based model for outlier detection in vibration signals is proposed, where the location of outliers within the vibration observation is marked by a combination of a spatial label and a temporal label.

On the use of dynamically varied loudspeaker spacing in wave field synthesis
Rishabh Ranjan,Woon-Seng Gan +1 more
TL;DR: In this article, the performance of dynamically modified loudspeaker array whose spacing varies with the audio signal frequency content is analyzed to avoid spatial aliasing at relatively low frequencies as compared to uniformly fixed array spacing in conventional WFS setup.

Sound field separating on arbitrary surfaces enclosing a sound scatterer based on combined integral equations
TL;DR: The separated incident and scattering sound fields agree well with the original corresponding fields described by analytical expressions, which validates the effectiveness and accuracy of the combined integral equations based separation method.
