Diffraction Culling for Virtual-Acoustic Simulations
Acta Acustica united with Acustica, 2008Acoustic simulations of complex virtual environments typically are created with geometrical-acoustics techniques. Such simulations can be augmented with edge diffraction modeling for improved accuracy, but not without a significant increase in processing time due to the additional propagation paths which must be considered and the computational ...

Simulation of acoustic fields of synphase electromagnetic-acoustic transducers
Russian Journal of Nondestructive Testing, 2013A model of the formation of acoustic fields of a synphase EMA transducer of longitudinal and transverse waves in the form of a phased array of elements with a current is proposed. This model takes several parameters into account, such as the number and dimensions of individual elements of the array and its aperture, the operating frequency, and the gap

Numerical Simulation of 3D Acoustic Logging
2007A Finite-difference method for simulation of sonic waves propagating in a vicinity of a borehole filled with fluid and surrounded by a 3D heterogeneous elastic medium is developed. The method utilizes an explicit second order of approximation FD scheme on staggered grids that approximates the elastodynamic system of equations in cylindrical coordinates.

Simulation of acoustical parameters of churches in a virtual acoustics laboratory
The Journal of the Acoustical Society of AmericaCurrent ISO standards for acoustical assessment limit the use of traditional mono-dimensional microphones for measuring equipment. However, microphone arrays offer more accurate spatial information compared to traditional microphones. This presents an opportunity to enhance research on architectural acoustics and preserve the acoustics of cultural ...
