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...
متن کاملArchitectural 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...
متن کاملArchitectural 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...

متن کاملArchitectural Acoustics: Towards a Benchmark in Computational Room Acoustics
In 1995, an intercomparison on room acoustics computer simulations was launched, the so-called round robin I. The object of interest was a mid-sized auditorium. That project also included a small measurement project, where sessions of impulse response measurements were carried out with several teams and instrumentation. Since that time, the variations in the results obtained by computer simulat...
