Boundary Conditions for Room Acoustic Simulations
ثبت نشده
چکیده
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 data of boundary conditions such as absorption and scattering coefficients. The influence of uncertainties of this data on room impulse responses and room transfer functions is discussed in comparison of wave and geometrical acoustics.

On boundary conditions for the diffusion equation in room-acoustic prediction: Theory, simulations, and experiments.
This paper proposes a modified boundary condition to improve the room-acoustic prediction accuracy of a diffusion equation model. Previous boundary conditions for the diffusion equation model have certain limitations which restrict its application to a certain number of room types. The boundary condition employing the Sabine absorption coefficient [V. Valeau et al., J. Acoust. Soc. Am. 119, 150...
متن کاملEstimating surface acoustic impedance with the inverse method.
Sound field parameters are predicted with numerical methods in sound control systems, in acoustic designs of building and in sound field simulations. Those methods define the acoustic properties of surfaces, such as sound absorption coefficients or acoustic impedance, to determine boundary conditions. Several in situ measurement techniques were developed; one of them uses 2 microphones to measu...

This paper addresses the influence of boundary conditions and small-scale effect on the free vibration of nano-plates using molecular dynamics (MD) and nonlocal elasticity theory. Based on the MD simulations, Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is used to obtain fundamental frequencies of single layered graphene sheets (SLGSs) which modeled in this paper as the mo...
متن کاملIn situ estimation of acoustic impedance on the surfaces of realistic interiors: an inverse approach
In situ measurement of acoustic impedance is traditionally performed using pairs of microphones located close to the test surface. However, this method becomes troublesome if inaccessible complex-shaped surfaces, such as those in a real room, are considered. To overcome this problem a method to estimate the normal acoustic impedance on the interior surfaces of a room is proposed. As input data,...
متن کاملIn-situ estimation of acoustic impedance on the surfaces of a room for inverse sound rendering
We present a method based on the inverse boundary element method (IBEM) for the in-situ estimation of normal acoustic impedances of the surfaces in a room. As input to the inverse process, this technique uses the geometry of the interior space, the position and strength of the sound source, and a set of sound pressures measured at random positions in the acoustic field. Previous work in inverse...
