Reverberant sound field equalisation for an enhanced stereo playback experience [PDF]
arXiv, 2023 The topic of room equalisation has been at the forefront of research and product development for many years, with the aim of increasing the playback quality of loudspeakers in reverberant rooms. Traditional room equalisation systems comprise of a number of filters that when applied to the primary loudspeakers, additional room colouration is compensated

A Multi-Tone Sound Absorber Based on an Array of Shunted Loudspeakers
Applied Sciences, 2018 It has been demonstrated that a single shunted loudspeaker can be used as an effective low frequency sound absorber in a duct, but many shunted loudspeakers have to be used in practice for noise reduction or reverberation control in rooms, thus it is ...

Spatial resolution of late reverberation in virtual acoustic environments [PDF]
arXiv, 2021 Late reverberation involves the superposition of many sound reflections resulting in a diffuse sound field. Since the spatially resolved perception of individual diffuse reflections is impossible, simplifications can potentially be made for modelling late reverberation in room acoustics simulations with reduced spatial resolution.

Robust single- and multi-loudspeaker least-squares-based equalization for hearing devices [PDF]
arXiv, 2021 To improve the sound quality of hearing devices, equalization filters can be used that aim at achieving acoustic transparency, i.e., listening with the device in the ear is perceptually similar to the open ear. The equalization filter needs to ensure that the superposition of the equalized signal played by the device and the signal leaking through the ...
