IEEEArtificial reverberators provide a computationally viable alternative to full-scale room acoustics simulation methods for deployment in interactive, immersive systems. Scattering delay network (SDN) is an artificial reverberator that allows direct parametric control over the geometry of a simulated cuboid enclosure as well as the directional characteristics of the simulated sound sources and microphones. This paper extends the concept of SDN reverberators to multiple enclosures coupled via an aperture. The extension allows independent control of the acoustical properties of the coupled enclosures and the size of the connecting aperture. The transfer function of the coupled-volume SDN system is derived. The effectiveness of the proposed method is evaluated in terms of rendered energy decay curves in comparison to full-scale ray-tracing models and scale model measurements.

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...
Source directivity simulation in digital waveguide mesh based room acoustics models Hacıhabiboğlu, Hüseyin; Günel Kılıç, Banu (null; 2007-03-15) Digital waveguide meshes provide a computationally simple physical modelling approach for simulating wave propagation inside enclosures such as rooms. A digital waveguide mesh allows access both to the pressure values at scattering junctions and to the incoming and outgoing wave variables at those junctions. It is thus possible to access both the pressure and the velocity components of the simulated sound field. This paper proposes a simple method to excite a digital waveguide mesh with outgoing wave variab...
Simulation of Directional Microphones in Digital Waveguide Mesh-Based Models of Room Acoustics Hacıhabiboğlu, Hüseyin; Günel Kılıç, Banu (2010-02-01) Digital waveguide mesh (DWM) models are time-domain numerical methods providing computationally simple solutions for wave propagation problems. They have been used in various acoustical modeling and audio synthesis applications including synthesis of musical instrument sounds and speech, and modeling of room acoustics. A successful model of room acoustics should be able to account for source and receiver directivity. Methods for the simulation of directional sources in DWM models were previously proposed. T...
Federation architecture modeling: A case study with NSTMSS Molla, Ayhan; Sarioǧlu, Kaan; Topçu, Okan; Adak, Mehmet; Oğuztüzün, Mehmet Halit S. (null; 2007-12-01) We discuss the practical issues in modeling federation architectures in the case of Naval Surface Tactical Maneuvering Simulation System (NSTMSS), an HLA-based distributed interactive simulation system. We model the architecture of NSTMSS conforming to the Federation Architecture Metamodel (FAMM). FAMM provides a formalized language to specify the communication behaviors of federates along with their object models. Federate behavior specification is based on Live Sequence Charts. A federation architecture m...
Voluntary Behavior on Cortical Learning Algorithm Based Agents Sungur, Ali Kaan; Sürer, Elif (2016-09-23) Operating autonomous agents inside a 3D workspace is a challenging problem domain in real-time for dynamic environments since it involves online interaction with ever-changing decision constraints. This study proposes a neuroscience inspired architecture to simulate autonomous agents with interaction capabilities inside a 3D virtual world. The environment stimulates the operating agents based on their place and course of action. They are expected to form a life cycle composed of behavior chunks inside this ...
