Session 5pMU Musical Acoustics and Structural Acoustics and Vibration: Computational Methods in Musical Acoustics II

Real-time auralization of physical models has attracted vivid interest over the last years. This is mainly due to the rising computational capabilities of personal computers and the accessibility of specialized (external) accelerating hardware, like GPGPUs (generalpurpose graphics processing units) or FPGAs (field programmable gate arrays). In this work, an extended framework of real-time physi...

Recent Developments in Acoustics and Vibration

In recent years there have been rapid advances in digital computers, the miniaturization of electronic circuits and the development of new materials. In the acoustics and vibration fields these advances have led to a continual increase in computational power and speed, improved acoustics and vibration transducers and instrumentation and better measurement techniques. In many cases the developme...

Vibration-Acoustics Study of R410A Rotary Compressors

This paper demonstrates a typical process to investigate the vibro-acoustic behavior of R410A rotary compressors. The compressor shell is usually the main noise radiator in a rotary compressor. However, the accumulator shell can be a significant noise source as well, although its size is relatively small. Sound performance of a rotary compressor is affected not only by the dynamic characteristi...
