Topological Sound Propagation with Reverberation Graphs

Reverberation graphs is a novel approach to estimate global soundpressure decay and auralize corresponding reverberation effects in interactive virtual environments. We use a 3D model to represent the geometry of the environment explicitly, and we subdivide it into a series of coupled spaces connected by portals. Off-line geometrical-acoustics techniques are used to precompute transport operato...

Mid Frequency Bottom-Interacting Sound Propagation and Reverberation in the Baltic

Abstract: The experiment BAROC (Baltic Acoustics on Rocky Outcrops) was performed in May 2002. Analysis and modelling of part of the received data are reported here, concerning transmission loss and reverberation in a shallow-water area south of Stockholm. LFM pulses were transmitted in two directions with frequency content between 500 and 5500 Hz. In both directions a clear sound channel was o...

Experiments in Room Acoustics: Modelling of a Church Sound Field and Reverberation Time Measurements

In this paper a study of the acoustical response of a new built church is shown. This study is based on the measurement of reverberation time, adopting the noise interrupted method, according to the International Standard. This method allows to evaluate the reverberation time by means of acoustical sound level acquisition and analysis. The reverberation time is one of the principal parameters t...

Measurements of anisotropic sound propagation in glass wool

The attenuation coefficient and phase velocity of plane sound waves propagating in three perpendicular directions in glass wool were measured in the frequency range 50-10,000 Hz. For glass wool of mass density 14 kg/m3 at the frequency 1,000 Hz, the attenuation constant for propagation perpendicular to the glass wool sheets was 75 dB/m, and for propagation parallel with the sheets 57 dB/m. For ...

Teleconnection between the Arctic Oscillation and Hudson Bay river discharge

[1] Rising surface air temperatures in response to anthropogenic forcing are intensifying the global hydrologic cycle. Some of the more dramatic signs of climate change are increasing precipitation, evaporation, and freshwater discharge in continental river basins draining to high-latitude oceans. At regional scales, however, an acceleration of the hydrologic cycle is not always detected. In co...
