Room acoustics simulation is achieved by digitally defining delay and weighting parameters and generating sampled analog signal responses. In the early portion of a response term an accurate impulse response is provided and subsequently high echo density is simulated using sampled analog signal Schroeder sections. A sampled data analog signal device is

Passive time-domain numerical designs for room acoustics simulation [PDF]
Proceedings of Meetings on Acoustics, 2016 The design of stable time domain numerical simulation methods for room acoustics simulation is challenging problem. One chief difficulty is in the determination of appropriate stable boundary terminations, particularly when the room geometry is irregular,

Acoustic Analysis of Various Purposes Rooms Using Measurements and Simulations
2021 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2021Acoustic properties affect the way one experiences sound in a room ; sound listener or microphone will receive the sound in a form that might be more or less understandable, influenced by the room's acoustic properties. Assessment of a room's acoustic properties can be made on-site and by using simulation software.

Acoustic simulations of studio control rooms
The Journal of the Acoustical Society of America, 2002The results of studio-control-room computer simulations with a ray-tracing-type computer program will be presented. Although the validity of ray-tracing simulations of small rooms and at low frequencies may be questionable, the early time echogram at mid and high frequencies obtained by ray tracing provide essential information. Reflections up to 20 ms

Simulating environmental and psychological acoustic factors of the operating room
The Journal of the Acoustical Society of America, 2015In this study, an operating room simulation environment was adapted to include quadraphonic speakers, which were used to recreate a composed clinical soundscape. To assess validity of the composed soundscape, several acoustic parameters of this simulated environment were acquired in the presence of alarms only, background noise only, or both.

Consulting applications for an acoustical simulation room.
The Journal of the Acoustical Society of America, 1992An acoustical simulation room was constructed for acoustical consulting use. The design criteria called for a space that could simulate the background noise, reverberation, spectral, time based, and directional response of proposed and existing spaces. Readily available professional audio and acoustical products were utilized for implementation into a ...

Investigating Room Acoustics by Simulations and Measurements
Noise & Vibration Worldwide, 2013Measurements in room acoustics are often used as the true reference of reality, while simulations are considered to be only a crude representation of it. However, both approaches have their own challenges and limitations, so measuring an impulse response and deriving room acoustic parameters correctly may be more difficult than it appears at first ...

Level of detail in room-acoustic simulation
The Journal of the Acoustical Society of America, 2019The quality of present-day room acoustic simulations depends on the quality of the boundary conditions and of the underlying CAD room models. A “high-resolution” room model does not mean that it needs to have a visually perfect geometrical fine structure.

Modeling binaural receivers in finite difference simulation of room acoustics
The Journal of the Acoustical Society of America, 2013Binaural room impulse responses are important for auralization as well as for objective research in room acoustics. In geometrical room simulation methods, obtaining such responses is easily achieved by convolving each computed reflection tap with a corresponding pre-measured angle-dependent head-related impulse response.

Directional source modeling in wave-based room acoustics simulation
2017 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2017Wave-based modeling in room acoustics and virtualisation applications constitutes an alternative to geometric or ray-based approaches; finite difference time domain (FDTD) methods, defined over regular grids, are an excellent match to parallel architectures.
