Session 4pAAa: Room Acoustics Computer Simulation II 4pAAa2. Modeling (Non-)uniform scattering distributions in geometrical acoustics
In most cases, a surface is not ideally smooth. It rather contains regular and irregular dents, bumps and other textures that influence the reflection of the incident wave. A reflection on such a corrugated surface causes a frequency-dependent redirection of the incident sound energy outside the specular direction, called scattering. While the computation of the specular part is well elaborated...
متن کاملIntegration of edge-diffraction calculations and geometrical-acoustics modeling
In time-domain simulations of sound propagation and/or scattering, it is possible to model the geometricalacoustics (GA) components and the edge-diffraction components separately and combine the results into a “total” impulse response. However, such separate calculations can limit the efficiency and accuracy of the simulations because the two components are not independent. This paper presents ...
متن کاملUniform Transformation of Non-Separable Probability Distributions
A theoretical framework is developed to describe the transformation that distributes probability density functions uniformly over space. In one dimension, the cumulative distribution can be used, but does not generalize to higher dimensions, or non-separable distributions. A potential function is shown to link probability density functions to their transformation, and to generalize the cumulati...
متن کاملTesting non-uniform k-wise independent distributions
A distribution D over Σ1 × · · · × Σn is called (non-uniform) k-wise independent if for any set of k indices {i1, . . . , ik} and for any z1 · · · zk ∈ Σi1 × · · · × Σik , PrX∼D[Xi1 · · ·Xik = z1 · · · zk] = PrX∼D[Xi1 = z1] · · ·PrX∼D[Xik = zk]. We study the problem of testing (non-uniform) k-wise independent distributions over product spaces. For the uniform case we show an upper bound on the ...
متن کاملGeometrical-Acoustics-based Ultrasound Image Simulation
Brightness modulation (B-Mode) ultrasound (US) images are used to visualize internal body structures during diagnostic and invasive procedures, such as needle insertion for Regional Anesthesia. Due to patient availability and health risks—during invasive procedures—training is often limited, thus, medical training simulators become a viable solution to the problem. Simulation of ultrasound imag...
