High-sensitivity gas leak detection sensor based on a compact microphone array
Measurement, 2021Early detection of tiny leaks in gas-pressurized vessels and pipelines can prevent disasters. Algorithm and sensor developments can enable acoustic methods to achieve high-sensitivity online leak detection by monitoring the sound generated by a leak and ...

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021
In this paper, we present a novel framework of beamforming robust for a microphone array rotation. In most array signal processing methods, the time-invariant transfer system from a source to a microphone is assumed for calculating a spatial filter. This

Symphony: localizing multiple acoustic sources with a single microphone array
ACM International Conference on Embedded Networked Sensor Systems, 2020Sound recognition is an important and popular function of smart devices. The location of sound is basic information associated with the acoustic source.

The identification of acoustic sources in a three-dimensional (3D) domain based on measurements with an array of microphones is a challenging problem: it entails the estimation of the angular position of the sources (direction of arrival), distance ...

Design study on microphone arrays
2015 IEEE International Conference on Digital Signal Processing (DSP), 2015This paper presents a design of microphone array system that is intended for conference room applications. Different microphone array configurations have been considered in this work to demonstrate the importance of array layout. The filter-and-sum broadband beamformer is designed by using weighted least square (WLS) optimization method.

Bioacoustics, 2020
Flight calls, the quiet calls emitted by migratory birds on the wing, offer opportunities to understand the behaviour of birds during migration. We test the effectiveness of an eight-element microphone array for three-dimensional triangulation of the ...

Microphone arrays and speaker identification
IEEE Transactions on Speech and Audio Processing, 1994Hands-free operation of speech processing equipment is sometimes desired so that the user is unencumbered by hand-held or body-worn microphones. This paper explores the use of array microphones to capture speech under adverse acoustic conditions, and provide input to a system for automatic speaker identification.

Beamforming of phased microphone array for rotating sound source localization
, 2020Phased microphone array beamforming has become a standard technique to localize sound sources. For localization of rotating sound sources at free-space conditions in the frequency domain, a number of algorithms have been investigated.
