Simulation of the acoustics of coupled rooms is an important problem not only in architectural acoustics but also in immersive audio applications that require acoustic simulation at interactive rates. Requirements for such applications are less demanding for accuracy but more demanding for computational cost. Scattering delay network (SDN) is a real-time, interactive room acoustics simulator for cuboid rooms. SDN affords an exact simulation of first-order early reflections, a gracefully degrading simulation of second and higher-order specular reflections and an accurate simulation of the statistical properties of the late reverberation. We propose coupled-volume SDN (CV-SDN) as an extension of the SDN model to simulate acoustics of coupled volumes. The proposed model retains the desirable characteristics of the original SDN model while allowing the simulation of double-slope decays with direct control over the simulated aperture size. The double-slope characteristics of room impulse responses simulated with CV-SDN agree well with those of measured impulse responses from a scale model and state-of-the-art room acoustics simulation software.

Analysis and Design of Multichannel Systems for Perceptual Sound Field Reconstruction De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2013-08-01) This paper presents a systematic framework for the analysis and design of circular multichannel surround sound systems. Objective analysis based on the concept of active intensity fields shows that for stable rendition of monochromatic plane waves it is beneficial to render each such wave by no more than two channels. Based on that finding, we propose a methodology for the design of circular microphone arrays, in the same configuration as the corresponding loudspeaker system, which aims to capture inter-cha...
Elastic waveform inversion using Gauss-Newton method Sheen, Dong-hoon; Baag, Chang-eob; Tuncay, Kağan; Ortoleva, Peter J. (2005-01-01) Seismic waveform inversion has been solved usually by a gradient type approach for acoustic media. In this paper, we present an elastic waveform inversion method based on the Gauss‐Newton method. Elastic wave propagation simulation and inversion are both implemented in the time domain. The partial derivative wavefields are computed explicitly using convolutions of forward and reciprocal wavefields. Numerical experiments show that the Gauss‐Newton elastic waveform inversion significantly improves of resolvin...
Efficient Synthesis of Room Acoustics via Scattering Delay Networks De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran; Smith, Julius O. (2015-09-01) An acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed. All parameters of the reverberator are derived from physical properties of the enclosure it simulates. It allows for simulation of unequal and frequency-dependent wall absorption, as well as directional sources and microphones. The reverberator renders the first-order reflections exactly, while making progressively coarser approximations of higher-order reflections. The rate of energy decay is clo...
Scattering delay networks with aperture size control for simulating coupled volume acoustics Atalay, Timuçin Berk; Hacıhabiboğlu, Hüseyin; Department of Modeling and Simulation (2019) Artificial reverberators provide a computationally viable alternative to full-scale room acoustics simulation methods when used in interactive, immersive systems. Scattering delay network (SDN) is a relatively recent artificial reverberator that allows direct parametric control over the geometry of a simulated rectangular enclosure as well the directional characteristics of the simulated sound sources and microphones. Coupled volume SDN aims to extend the SDN structure for enclosures coupled via an aperture...
Spherical harmonics based acoustic scene analysis for object-based audio Çöteli, Mert Burkay; Hacıhabiboğlu, Hüseyin; Department of Information Systems (2021-2-19) Object-based audio relies on elemental audio signals from individual sound sources and their associated metadata to be reconstructed at the listener side. While defining audio objects in a production setting is straightforward, it is not trivial to extract audio objects from more realistic recording scenarios such as concerts. Thus, existing object-based audio standards also define scene-based formats alongside objectbased representations that provide immersive audio, but without the flexibility provided by...
