Modeling Techniques for Virtual Acoustics
Author Lauri Savioja Title Modeling Techniques for Virtual Acoustics The goal of this research has been the creation of convincing virtual acoustic environments. This consists of three separate modeling tasks: the modeling of the sound source, the room acoustics, and the listener. In this thesis the main emphasis is on room acoustics and sound synthesis. Room acoustic modeling techniques can be...

متن کاملVirtual 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...
متن کاملVirtual Acoustics in Psychoacoustics and Audiology
While initially being focused predominantly on the visual modality, research and applications in the field of augmented and virtual reality environments recently started expanding towards the auditory modality. In this context, two major fields of research interrelating virtual reality and Psychoacoustics or hearing research in general have attracted growing interest: 1) the evaluation of virtu...
متن کاملCollagen Fibril Formation at Microgravity Conditions:
Collagen molecules can selfassemble from dilute solutions into axially ordered fibrils similar to those seen in vivo in tendon and skin. At neutral pH the self-assembly has a negative temperature coefficient, thus molecules can be held in solution at 4-15 C; a temperature jump to 25-30 C will then lead to fibrillogenesis under controlled conditions. Two experiments have been carried out under...
