Resonant Vessels in Russian Churches and Their Study in a Concert Hall

Acoustics, 2020
Resonant vessels in ancient and medieval buildings are the subject of some historical and acoustic research today. There have been a number of detailed surveys of European churches, where acoustic pots remain in the buildings.

High-Performance Extrinsic Fabry-Perot Fiber Optic Acoustic Sensor Based on Au/PI Composite Film

IEEE Access
This paper reports a novel Fabry-Perot fiber optic microphone based on Au/PI composite film, with an optimal F-P cavity length of $500 \, \mu \text{m}$ , and the maximum extinction ratio (ER) obtained is about 12 dB.

Interlaboratory Comparison and Analysis of Bidirectional Scattering Coefficients for Various Surfaces

Acta Acustica
Accurate modeling of acoustic scattering is essential for realistic sound-propagation simulations in architectural environments. Traditional random-incidence models fail to represent directional scattering from structured surfaces, motivating the need ...
