Optimizing acoustic conditions for two lecture rooms in Faculty of Agriculture, Cairo University

Ain Shams Engineering Journal, 2017
This paper analyses the acoustic conditions inside two lecture rooms in faculty of agriculture, Cairo University, based on field measurements and simulation technique. Ambient noise and reverberation time were measured in the unoccupied rooms.

Implementation and Perceptual Evaluation of a Simulation Method for Coupled Rooms in Higher Order Ambisonics [PDF]

, 2014
A fast and perceptively plausible method for rendering acoustic scenarios with moving sources and moving listeners is presented. The method is principally suited for application in dynamic and interactive evaluation environments (e.g., for hearing aid ...

Dense multipath component polarization and wall attenuation at 1.35 GHz in an office environment [PDF]

, 2018
This paper presents an analysis of dense multipath components in office meeting rooms. Radio channel sounding measurements at 1.35 GHz were performed with transmitter and receiver in the same room (intra-room) and in adjacent rooms (inter-room). Specular

The effect of simulated room acoustic parameters on the intelligibility and perceived reverberation of monosyllabic words and sentences.

Journal of the Acoustical Society of America, 2020
Individual acoustic parameters of reverberation have the potential to affect both the intelligibility of speech and the degree of perceived reverberation.

Proposal of a simplified methodology for reverberation time prediction in standard medium size rooms with non-uniformly distributed sound absorption

Acta Acustica, 2023
Sabine, Eyring and Millington formulas are commonly used for reverberation time prediction, mainly, as a calculation tool in building acoustics design.

Forum-Pre-Sabine room acoustic assumptions on reverberation and their influence on room acoustic design.

Journal of the Acoustical Society of America, 2020
With his work on the Fogg Art Museum and Boston Symphony Hall between 1895 and 1900, Wallace C. Sabine laid a foundation for the field of architectural acoustics as a science.

Effects of virtual acoustics on dynamic auditory distance perception [PDF]

, 2017
Sound propagation encompasses various acoustic phenomena including reverberation. Current virtual acoustic methods, ranging from parametric filters to physically-accurate solvers, can simulate reverberation with varying degrees of fidelity.

Comparison of Transfer Function Method and Reverberation Room Method in Measuring the Sound Absorption Coefficient of Rice Straw Particle Mat

Journal of the Korean Wood Science and Technology, 2018
1) This study estimates the sound absorption capability of rice straw particle mats by two methods: the transfer function method and the reverberation room method. In the reverberation method, the central frequency was set to the one-third octave band in
