i don't know, but with the cd3000s, i hear a "reverb" or whatever you want to call it on a much wider range of sounds than i would chalk up to simple resonance. i do, however, acknowledge that this is not due to their closed nature, as the 7506s have barely any of this "reverb" in comparison.
Originally posted by WmAx Simply because a headphone(or speaker) is 'open' does not mean that it is immune to resonance(s). A correctly designed enclosure can yeild little to no appreciable resoance(s) that are/is destructive. However, the tranducer itself, as well as the materials the device is made of will/can hve their own resonance(s), open or not. Obviously, this is tougher to deal with in a closed design since more energy is contained in the structure, as opposed to an open design that allows a large percentage of the total acoustic power to be dispersed into open air. Once again, through careful engineering, these resoances can be shifted, damped, etc., in order to optimize either design(minimze audibility), open or closed. Logistics do declare that this will be more difficult and expensive in a closed design, as compared to an equivalent open design. I am not sure I know what people mean by 'echo' or 'reverb' when they speak of headphones. I can only speculate. In a way, a severe resonance will resemble 'reverb' in that it's a slowly decaying signal, however it will be in (a) very narrow band(s). As far as echo, I am not sure what this refers too. At no time can i think of any instance where a sound could be identified as an echo inside of a headphone. Their is not adequate dealy time between any dimension. I belive this is typically a misidentification of a resonance, or in some cases, even the imagination, after reading some of teh comical stuff around here. -Chris |
