Peripheral Sonification by Means of Virtual Room Acoustics

Audio-visual Virtual Reality System for Room Acoustics

We present an audio-visual Virtual Reality display system for simulated sound fields. In addition to the room acoustic simulation by means of phonon tracing and finite element method this system includes the stereoscopic visualization of simulation results using a 3D back projection system as well as auralization by use of a professional sound equipment. For auralization purposes we develop a s...

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...

Virtual Acoustics by Numerical Simulation

New emerging multimedia standards, like the MPEG-4 standard allow the creation of virtual or synthetic acoustical environments. To auralize an environment from its geometric description, simulation algorithms for acoustic wave propagation are required. The different methods used for computational modeling of room acoustics can be divided into three groups [1]: statistical models, ray-based mode...

For Assessing Room Acoustics

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...
