Adaptation to room acoustics using the modified rhyme test.

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...

For Assessing Room Acoustics

A short introduction to room acoustics

Sound waves are mechanical waves and the behaviours of fixtures inside rooms are governed by rules in physics. These fixtures are classified into three groups: reflectors, diffusers and absorbers, and the physical properties are investigated. The important parameters in determining acoustic quality of rooms are introduced. On the other hand, it is shown that limitations exist on applying these ...

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...

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...
