Resonance in rear horns

Jaime · 22nd February 2007, 12:31 PM

Hi all :
In rear horns we have a resonance in the mouth of the horn. The frequency is depending of the length of the horn. A 2.70m length horn have a resonance at 127 Hz.

How I can attenuate it?
The back mouth is more problematic?

Best regards Jaime

Hi,

Interesting questions.

How do you know about the resonance? Is it the result of transducer excitement from the throat? Is is excited by an external source at the mouth?
