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...

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...

Research on room acoustic simulation focuses on more accurate modeling of wave effects in rooms. Today, also wave models (e.g., the boundary element method and the finite differences in time domain technique) can be used for higher frequencies, thus, in the geometrical acoustics (GA) domain. Simulations in architectural acoustics are powerful tools but their reliability depends on the input dat...
