Trombe e guide d'onda: differenze tra i profili
Inviato: lunedì 7 febbraio 2011, 1:13
Non so se questo è il titolo migliore.
Chiederei agli esperti di aiutarci a capire le differenze tra trombe e guide d'onda, le varie differenze tra i profili, e il campo di utilizzo consigliato per ciascuna tromba e w.g.. Se è possibile, anche la loro classificazione in termini di generazione (I, II, o III)
Giusto per nominarne qualcuna: esponenziale, iperbolica, conica, voight, constant directivity (ev), tractrix, mantaray (altec), multiple entry horn, hughes (peavey), bi-radial (jbl), geddes' oblate spheroid, kugelwellen (avantgarde), le cleach, buttcheek (jbl), econowave (jbl), bullet (turbosound), iwata...

Horns versus Waveguides:
Originally, a horn was generally used to increase the acoustic output of a transducer by providing improved loading as compared to directly coupling the transducer to the open environment.
As stated by Harry Olsen in Acoustical Engineering, “The principal virtue of a horn resides in the
possibility of presenting practically any value of acoustical impedance to the sound generator.”
As a side benefit, it provided some directivity control to the dispersion of acoustical energy.
Today’s so-called “waveguides” are horns with the directional characteristics being the prime
design criteria over optimum driver loading. This is due to the fact that today’s compression
drivers are very efficient and have a much higher power-handling capability than in past
decades. This allows the designer to pay more attention to the directional characteristics
than the loading of the driver in newer horn designs.
