Boundary Conditions for Room Acoustic Simulations
Research on room acoustic simulation focuses on more accurate modeling of wave effects in rooms. Today, also wave models (e.g., the boundary element method and the finite differences in time domain technique) can be used for higher frequencies, thus, in the geometrical acoustics (GA) domain. Simulations in architectural acoustics are powerful tools but their reliability depends on the input dat...
متن کاملICA 2010 paper
FDTD has become a popular tool in acoustic modelling in recent years. A main attraction of FDTD is that it can be implemented in computer code easily using simple straightforward marching algorithms and finite difference equations. However, this simplicity comes at a price. Dispersion errors, source scattering, and frequency dependent boundary reflections are just a few of the problems that FDT...
متن کاملAn explicit time-domain finite-element method for room acoustics simulation
The time-domain finite-element method (TD–FEM) is a reliable numerical method for room acoustics simulation. With the recent progress in computer technology, the use of FEM at high frequencies has become a realistic option. However, efficient simulation at high frequencies is still cited as a challenging task. One of the key to realize such simulation is to reduce the discretization error calle...
متن کاملThe Acoustic Diffusion Model for Single and Coupled Interior Volumes Using the Boundary Element Method
Recently, a new model for the propagation of sound in interior volumes known as the acoustic diffusion model has been explored as an alternative method for acoustic predictions and analysis. The model uses statistical methods standard in high frequency room acoustics to compute a spatial distribution of acoustic energy over time as a diffusion process. For volumes coupled through a structural p...
متن کاملModeling of Reflections and Air Absorption in Acoustical Spaces — a Digital Filter Design Approach
In this paper, a method is presented for modeling sound propagation in rooms using a signal processing approach. Low order digital filters are designed to match to sound propagation transfer functions calculated from boundary material and air absorption data. The technique is applied to low frequency, finite difference time domain (FDTD) simulation of room acoustics and to real-time image-sourc...
