A Stable Sound Field Control Method for a Personal Audio System
Applied Sciences, 2023 A personal audio system has a wide application prospect in people’s lives, which can be implemented by sound field control technology. However, the current sound field control technology is mainly based on sound pressure or its improvement, ignoring ...

Robust single- and multi-loudspeaker least-squares-based equalization for hearing devices
EURASIP Journal on Audio, Speech, and Music Processing, 2022 To improve the sound quality of hearing devices, equalization filters can be used to achieve acoustic transparency, i.e., listening with the device in the ear is perceptually similar to the open ear.

Controlling the perceived distance of an auditory object by manipulation of loudspeaker directivity.
Journal of the Acoustical Society of America, 2015 This work presents a method to control the perceived distance of an auditory object by changing the directivity pattern of a loudspeaker and consequently the direct-to-reverberant ratio at the listening spot.

Spatial Reverberation and Dereverberation using an Acoustic Multiple-Input Multiple-Output System [PDF]
J. Audio Eng. Soc, vol. 65, no. 1/2, pp. 42-55, 2017Methods are proposed for modifying the reverberation characteristics of sound fields in rooms by employing a loudspeaker with adjustable directivity, realized with a compact spherical loudspeaker array (SLA). These methods are based on minimization and maximization of clarity and direct-to-reverberant sound ratio.

Multichannel Active Noise Control with Exterior Radiation Suppression Based on Riemannian Optimization [PDF]
arXiv, 2023 A multichannel active noise control (ANC) method with exterior radiation suppression is proposed. When applying ANC in a three-dimensional space by using multiple microphones and loudspeakers, the loudspeaker output can amplify noise outside a region of target positions because most of current ANC methods do not take into consideration the exterior ...

Applied Sciences, 2020 Direct sound that is captured by the upper layer of a three-dimensional (3D) microphone array is typically regarded as vertical interchannel crosstalk (VIC), since it tends to produce an undesired effect of the sound source image being elevated from the ...

Equalization of loudspeaker response using balanced model truncation.
Journal of the Acoustical Society of America, 2015 Traditional loudspeaker equalization algorithms cannot decide the order of an equalizer before the whole equalization procedure has been completed. Designers have to try many times before they determine a proper order of the equalization filter. A method
