An archaeoacoustic study on shape: the case study of the Iffland Theatre’s history (1802–1817)
Previous studies have discussed six pre-Sabine quantifiable guidelines employed in room acoustic design: voice directivity, audience rake, “echo theory”, stage acoustics, reverberation, and length, width, and height ratios.

An Iterative Ray Tracing Algorithm to Increase Simulation Speed While Maintaining Overall Precision
Ray tracing is a frequently used method for acoustic simulations, valued for its calculation speed and ease of use. Although it is fast, there are no fully ray tracing-based real-time simulation methods or engines.

An Archaeoacoustics Analysis of Cistercian Architecture: The Case of the Beaulieu Abbey
The Cistercian order is of acoustic interest because previous research has hypothesized that Cistercian architectural structures were designed for longer reverberation times in order to reinforce Gregorian chants.

A filter representation of diffraction at infinite and finite wedges [PDF]
Diffraction of sound occurs at sound barriers, building and room corners in urban and indoor environments. Here, a unified parametric filter representation of the singly diffracted field at arbitrary wedges is suggested, connecting existing asymptotic ...

Ultrasonic monitoring of the VVER-1000 FA form change [PDF]
A procedure has been developed to determine the geometrical parameters of fuel assemblies (FA) by an ultrasonic pulse-echo technique used for all types of light-water reactor FAs. The measurement of geometrical parameters is achieved through the pairwise

Acoustic investigation on nozzles with different types of six lobed chevrons [PDF]
This paper deals with a few aspects of the notion of chevron and the process that helps reducing the noise pollution. Based on the gas dynamic and geometrical parameters of a single flow jet engine a model of CFD data processing is made.

Acoustic control study of turbofan nozzles with triangular chevrons [PDF]
This paper has a small part dealing with the notion of chevron and the process that helps reducing the noise pollution. Based on the gas dynamics and the geometrical parameters of the turbofan jet engine a model of CFD data processing is created. In this

An Acoustic Reconstruction of the House of Commons, c. 1820–1834
This paper presents an acoustic reconstruction of the UK House of Commons between c. 1820 and 1834. Focusing on a historically important site where political decisions were debated over the centuries, we aim to simulate and present the intangible ...
