Isoacoustics Gaia Isolation pods

[Confused]

Hi Confused,

Could you please explain a bit more in depth about what it is we're looking at above? Are those different frequencies? Is one inverted? I have no idea what I'm looking at other than some nice coloured lines.

Thanks in advance.

Yes, different frequencies.  No, the second one is not inverted.  They are two 'snips' from a REW frequency sweep curve, indicating the relative dB levels through the frequency range.  The first one is a reinforcement peak at something like 60Hz I think.  I am away from my music PC at the moment, so no access to the curves to double check the specific frequencies, not that the specific frequencies really matter here as this will be specific to the room and speaker placement.  The second snip is from a 'null' at a higher frequency.  So the peaks result from room reflections adding up, the nulls from them cancelling out.  So what the snips show is the feet actually reducing the peaks very slightly, and reducing the higher frequency null slightly.  I did zoom in / out of the REW display to make the difference in the peak of the curves as easy to see as possible when posted here.  I think the very slight difference in the curves do indicate the feet are doing something.

Of course this is based on one particular speaker design in one specific room, a sample of one with a relatively unusual speaker design.  So statistically of very limited value.  Hence I would be interested if Hifi_swlon could achieve anything similar with a test before and after his pending Iso Accoustics removal.  A data set of two is much better than one.
