Room Acoustics – Fundamentals and Computer Simulation
2018In room acoustics analytical formulas and computer simulations can be used to predict the acoustics of spaces, not only in terms of reverberation but other perceptual aspects, too, which are related to the perception of music or speech. In this context the room impulse response is the function of main interest. It can be measured by using sophisticated

Adaptive room acoustic response simulation: a virtual 3D application
2003 IEEE XIII Workshop on Neural Networks for Signal Processing (IEEE Cat. No.03TH8718), 2003In this paper we propose a method to simulate a 3D acoustical environment in which sound sources are positioned in well defined sides. Our method is real-time applications oriented, due to the low computational cost of the implemented operations. The spatial position that the human brain assigns to a sound is influenced mainly by the differences ...

Computer Simulations of Room Acoustics in Sporting Facilities
Advanced Materials Research, 2013The paper is focused on a solution with regards to acoustic problems inside of facilities for sporting activities. The evaluation of the acoustic parameters of the interior was done within a project called "Badminton Centre with Facilities", which was part of a master thesis at the Institute of Building Structures of the Faculty of Civil Engineering ...

Customized Room Acoustics Simulations Using Scripting Interfaces
Proceedings of Meetings on Acoustics, 2011Geometrical computer modeling is commonly used in consulting practice to make predictions of room acoustical quality. A large number of new parameters have been created by academicians and acousticians in recent years—so much so that it has been difficult for room acoustics simulation providers to include them all.

Computer Simulation of an Arbitrary Acoustical Field in Rooms
2017 Asia Modelling Symposium (AMS), 2017The work provides an algorithmic model of sound propagation in rooms with respect to the principles of the object-oriented programming paradigm, i.e. in terms of classes, their instances and relations in order to model the behavior of acoustical fields developed to support various sets of input parameters specifying radiation and propagation of ...

Principles of designing an algorithm for acoustic room multichannel simulation
Asia-Pacific Conference on Circuits and Systems, 2003The paper deals with the principles of realizing a multichannel simulation of an acoustic room (known as an artificial reverberation) as a discrete system. The resulting simulation algorithm describing the discrete system is to be adapted to realization in a DSP environment and should be capable of working in real time. A definition of the requirements

Real-time virtual room acoustic simulation
The Journal of the Acoustical Society of America, 2003A realistic virtual room acoustic simulation has been implemented on a PC-based computer in near real-time. Room acoustics are calculated by the image source method using realistic absorption coefficients for a variety of realistic surfaces and programmed in MATLAB.

Recent Progress in Room Acoustical Computer Simulations
Building Acoustics, 1997In the last decade computer simulations of sound fields in rooms have been developed for application in research and consulting. Some programs are commercially available. Most computer models are based on geometrical room acoustics and/or on statistical (radiosity) methods, thus not including wave phenomena such as diffraction.

A simulation package for room acoustics with an open interface
The Journal of the Acoustical Society of America, 1999The solution of complex acoustic problems of the low-frequency sound field presupposes the numeric implementation of the wave equation. Especially for the calculation of sound fields in a finite volume (interior problem), the method of the finite elements (FEM) can be applied.
