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: 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...

Immersive Visualization of Room Acoustics

Visualization of sound propagation inside rooms is one of the main purposes of room acoustic simulations. Visualization is often applied in teaching, but also consultants need visualization to understand better the propagation of sound waves in complex cases. Traditionally, propagation paths of sound rays or image sources (representing reflections) have been applied in visualization. In additio...

What do we know in room acoustics?

Room acoustics has a scientific interdisciplinary concept which will be further developed in future. During the last century, several dimensions of the overall listening impression in concert halls were identified which show a good correlation with corresponding objective measurement data. It can be summarized that the three most important factors (loudness, reverberance and spatial impression)...
