Experiments on redirection of organ pipe sound by coupling
Mendel Kleiner, Matthias Scholz, Munetaka Yokota · The Journal of the Acoustical Society of America · 2004
It is well known among organ builders that the sound of an organ pipe may be influenced by the addition of closely tuned pipes in the vicinity of the pipe. Rather than being a result of absorption of sound it is hypothesized that the effect is due to the sound being redirected due to coupling between pipes, similar to the coupling between elements in a Yagi antenna array. Measurement results will be shown and discussed. [Work supported by RPI and Chalmers University of Technology.]
