Recording, Processing, and Reproduction of Vibrations Produced by Impact Noise Sources in Buildings

Acoustics
Several studies on the perception of impact sounds question the correlation of standardized approaches with perceived annoyance, while more recent studies have come to inconsistent conclusions.

Residual Learning for Neural Ambisonics Encoders

CoRR
Emerging wearable devices such as smartglasses and extended reality headsets demand high-quality spatial audio capture from compact, head-worn microphone arrays. Ambisonics provides a device-agnostic spatial audio representation by mapping array signals to spherical harmonic (SH) coefficients. In practice, however, accurate encoding remains challenging.

Sound Field Reproduction Research and Its Applications in Cabin Noise Reproduction of Vehicles: A Review

Machines
Sound field reproduction (SFR) is vital for noise simulation and acoustic comfort optimization in vehicle cabins. This paper reviews three core SFR techniques: Wave Field Synthesis (WFS), Higher-Order Ambisonics (HOA), and Pressure Matching (PM).

DiffAU: Diffusion-Based Ambisonics Upscaling

CoRR
Spatial audio enhances immersion by reproducing 3D sound fields, with Ambisonics offering a scalable format for this purpose. While first-order Ambisonics (FOA) notably facilitates hardware-efficient acquisition and storage of sound fields as compared to high-order Ambisonics (HOA), its low spatial resolution limits realism, highlighting the need for ...

Providing Surround Sound with Loudspeakers: A Synopsis of Current Methods

Archives of Acoustics, 2013
Available methods for room-related sound presentation are introduced and evaluated. A focus is put on the synthesis side rather than on complete transmission systems. Different methods are compared using common, though quite general criteria.

The Mobile Ambisonics Equiptment Of The ICST

, 2010
The experience of having performed numerous concerts with the large technical setup required for Ambisonics has led to the development of equipment that is much easier to handle and that enables us to reduce drastically the amount of time and work used for its installation.

Assessing Ambisonics Sound Source Localization by Means of Virtual Reality and Gamification Tools

Applied Sciences
Sound localization is a key area of interest in auditory research, especially in complex acoustic environments. This study evaluates the impact of incorporating higher-order Ambisonics (HOA) with virtual reality (VR) and gamification tools on sound ...
