Infinite impulse response-based simulation of room acoustics
The Journal of the Acoustical Society of America, 2000In this work, the problem of filter construction for the point-to-point impulse response in a room is examined. Our particular interest is infinite impulse response (IIR) filters. It will be shown that such filters can be constructed from image-based models. The use of subband IIR filter models is investigated. Our model provides perfect reconstruction

Room acoustics simulation of hospital patient care-unit.
The Journal of the Acoustical Society of America, 2011Acoustical design challenges in hospitals are providing better communication to reduce medical errors and speech privacy that has also become a legal issue according to the Health Information Portability and Accountability Act (HIPAA). Some industrial products performance criteria are being exaggerated in the claims as solutions for better room ...

Binaural room acoustics simulation: Practical uses and applications
Applied Acoustics, 1992Abstract Binaural room acoustics simulation experience at the CSTB acoustics laboratory is presented. The method used for the prediction of the binaural impulse response involves three steps: geometrical, pseudostatistical and purely statistical. Needs for binaural technology and results already available are discussed.

Simulation and experimental study of room acoustics
2013Sound propagation is a complex subject, especially in an enclosure. The study of room acoustics involves not only a research into how sound is propagated in a room, but also a search into how to measure sound under different condition and how to control sound in the case of various wall materials.

Parallelized finite difference time domain room acoustic simulation
The Journal of the Acoustical Society of America, 2012A parallelized room acoustics simulator based on the finite difference time domain (FDTD) method is developed, utilizing a Blue Gene/L supercomputer. Wave-based methods such as FDTD are desirable for use in room acoustics simulations since they account for effects such as diffraction and interference.
