Kienle Resonator System

Although the area of even emittance is extended on the horizontal plane, the problem of an even sound distribution cannot be solved in a satisfactory way if the audience is seated at different heights with respect to the emitting device.

An example of the distribution of the sound wave's fundamental tone created in the tube is shown in the diagram by red curves.

The node is located at the height of the curve intersection, the anti-nodes occur close to the openings emitting the main part of the sound.

The oscillation of the air column and the sound emittance of the Kienle Resonator System occur in the same manner as in a traditional organ pipe.

The technical installation of a resonator system with organ characteristics is substantially simplified by the removal of the flow stimulation.

All the parts which generate and control the air flow in a conventional pipe organ are omitted and therefore reduce the amount of installation and maintenance work.

Instead of tin organ pipes, Kienle resonator tubes made of zinc or aluminum and also non-metallic materials such as acrylic glass or coated PVC.
