FAC Acoustics Study Set

The Set for the Study of Acoustics, "FAC" designed by EDIBON allows to perform all kinds of experiments related to acoustic waves (propagation, interferences, wave fronts, etc.).The most complete way to carry out the observation would be to fill the space with tiny microphones, placing them at the nodes of a fine three-dimensional spatial network that does not disturb the behavior of the waves. By means of acoustic emitters the waves would be produced and all the microphones would take data during a certain time with this imaginary procedure we would have information of everything that happened in all the points of the net at all times, being collected all the nuances of the experience.

The Set "FAC" is based on the reproducibility of a physical process. For this purpose, the computer-controlled robot arm sweeps a region of space measuring the intensity of the acoustic wave at equidistant points. The perfect synchronization between the transmitter and receiver, together with the control and management software, allows the student to visualize the propagation of the sound wave in space. The use of the control system with more than one emitter allows us to study the processes of constructive and destructive interference. The set is supplied with a set of acoustic materials (mirrors, lenses and diffraction gratings) that allow the study of reflection, refraction and dispersion processes, as well as acoustic shielding processes.
