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...

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...

Virtual acoustics and auralizations have been previously used to study the perceptual properties of concert hall acoustics in a descriptive profiling framework. The results have indicated that the apparent auditory distance to the orchestra might play a crucial role in enhancing the listening experience and the appraisal of hall acoustics. However, it is unknown how the acoustics of the hall in...
