Architectural Acoustics: Acoustics of Concert Halls II

Some high-resolution direction-of-arrival DOA estimation methods, such as the MUSIC method, have been developed based on vectorsensor array. However, these high-resolution methods suffer from serious drawbacks. Indeed, they are not able to estimate coherent signals and sensitive to calibration errors. Mainly to overcome these limitations and in particular to satisfy practical engineering applic...

Architectural Acoustics: Measurement of Room Acoustics I

A new acoustic measurement signal that is a hybrid signal of time-stretched pulse TSP , or lin-TSP, and logarithmic TSP log-TSP is proposed. The signal, referred to as warped-TSP Morise et al., IEICE Trans. Fundamentals, A, J89-A 1 , 7–14 2006 , has a single parameter to adjust for better measurements in accordance with ambient noise conditions. It also provides a means to eliminate harmonic di...

Architectural Acoustics: General Topics in Architectural Acoustics

The Audio Arts and Acoustics department at Columbia College in Chicago acquired a new building in 2003. The facility, a former bank, contained an old steel and concrete vault that was converted to a reverberation chamber. The acoustic properties of the space, including reverberation time, modal density, and early reflection maps were analyzed and compared to a computer model. Reflectograms were...

Session 5pMU Musical Acoustics and Structural Acoustics and Vibration: Computational Methods in Musical Acoustics II

Real-time auralization of physical models has attracted vivid interest over the last years. This is mainly due to the rising computational capabilities of personal computers and the accessibility of specialized (external) accelerating hardware, like GPGPUs (generalpurpose graphics processing units) or FPGAs (field programmable gate arrays). In this work, an extended framework of real-time physi...
