Synchronization of Organ Pipes
We report results on the synchronization of an organ pipe either by a second pipe or by a loudspeaker, positioned side by side. Classical theory suggests oscillation death for the synchronization of two organ pipes. With our measurements we clearly exclude this scenario. Rather, we identify the aeroacoustical coupling by the oscillating wind sheet at the pipe mouth as the source of a self-regul...
متن کاملModeling of Transient Flow in Plastic Pipes
We present a numerical code for calculating transient flow in plastic pipes, especially in the polyethylene pipe, to analysis water hammer phenomena. The set partial differential equations to be solved is obtained using conservation laws and behavior for the fluid and the pipe wall, associated with constitutive equations of the two media, and relationships compatibility of interfaces on velocit...
متن کاملComparison between subsonic flow simulation and physical measurements of flue pipes
Direct simulations of wind musical instruments using the compressible Navier Stokes equations have recently become possible through the use of parallel computing and through developments in numerical methods. As a first demonstration, the flow of air and the generation of musical tones inside a soprano recorder are simulated numerically. In addition, physical measurements are made of the acoust...
متن کاملSynchronization of organ pipes: experimental observations and modeling.
We report measurements on the synchronization properties of organ pipes. First, we investigate influence of an external acoustical signal from a loudspeaker on the sound of an organ pipe. Second, the mutual influence of two pipes with different pitch is analyzed. In analogy to the externally driven, or mutually coupled self-sustained oscillators, one observes a frequency locking, which can be e...
متن کاملSimulation of Reed Vibration in Lingual Organ Pipes
The functioning of the first type, the flue or labial pipe, was already investigated within previous extensive research projects. The second pipe type, the reed pipe, is less often installed in pipe organs, and only little research was done in this field so far. This is why this pipe type is now the focus of research of the working group ‚Musical Acoustics ‘ at the Fraunhofer Institute for Buil...
