Abstract
A method of determining the physical location of undesired resonance zones induced by acoustic feedback in a spring reverberation unit and damping the vibration of these resonance zones. The improved spring reverberation unit with damping material located at the resonance points of the unit produces a reverberated audio signal which is substantially free from the screeching and howling caused by acoustic feedback.
