Interface for Barge-in Free Spoken Dialogue System Based on Sound Field Reproduction and Microphone Array

EURASIP Journal on Advances in Signal Processing, 2007
A barge-in free spoken dialogue interface using sound field control and microphone array is proposed. In the conventional spoken dialogue system using an acoustic echo canceller, it is indispensable to estimate a room transfer function, especially when ...

Static and moving minimum audible angle: Independent contributions of reverberation and position [PDF]

JASA Express Letters
Two measures of auditory spatial resolution, the minimum audible angle and the minimum audible movement angle, have been obtained in a simulated acoustic environment using Ambisonics sound field reproduction.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Designing an Open-Back Enclosure to Mitigate Sound Leakage for Open-Ear Headphones

IEEE Access
Small open-ear headphones are comfortable because they do not block the auricle or ear canal, which eliminates the occlusion effect and enables users to hear ambient sounds naturally and achieve accurate binaural reproduction in principle. However, their

Spatial audio signal processing for binaural reproduction of recorded acoustic scenes – review and challenges

Acta Acustica, 2022
Spatial audio has been studied for several decades, but has seen much renewed interest recently due to advances in both software and hardware for capture and playback, and the emergence of applications such as virtual reality and augmented reality.

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
