Transient chaos in room acoustics
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1993The decay of sound in an auditorium due to absorption is central to the theory and practice of room acoustics. Within geometrical acoustics, this problem involves the partial trapping of chaotic ray trajectories in billiards, hence transient chaos. We first present a theoretical and numerical analysis of the decay of rays in 2-D chaotic billiards (2-D ...

In dedicated teleconference rooms, there is an acoustical conflict between finishes for optimum microphone pick-up and those for optimum speech intelligibility within the space. This paper looks at the implications of this for teleconference room finishes and geometries as well as other acoustically critical factors such as sound isolation and ambient ...

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

Equalizability of room acoustics
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992The sound quality of public address systems is largely dependent on the acoustical characteristics of the room or hall in which the sound is heard. Furthermore, the quality of sound often varies significantly over the listening space. Hence, even with good quality equipment (amplifiers and loudspeakers that contribute a minimum of linear and nonlinear ...

In this paper two acosutical models are investigated: imaginary source model and ray tracing model which calculated the energy impulse response and introduced many acoustical parameters of a selected room. Following an extensive objective acoustic measurement program made in V.
