How so? Most of those show peaks close enough 5k and 10k. The Russian one is just over smoothed. It's not unusual to see a discrepancy of around 500hz-1k between various rigs and calibrations. Don't expect electron microscope or even caliper level of precision with these graphs.
As always, it's the relative analysis with context that matters, not static absolutes.
I see. It never connected in my head that the peaks on the graph could be similar to what I was hearing but shifted higher or lower. This really helps. Thank you.
The 5 KHz peak seems to appear in measurements that use a simulated ear. There's always a narrow peak between 9-10 KHz with any headphones for me, it's due to my ear.
Thanks, I guess I need to check on that. I recall that my Sennheiser HD250 II has a huge peak around 10KHz even though the one or two graphs that I found of it didn't really show that at all. The only headphones which didn't have any annoying (sinegen) treble peaks was the Yamaha YH-1, but that one is on ear (and probably known to have a relatively rolled off treble response).
CSDs are a better way to confirm treble peaks. Look at GE's CSD graph. See the ridges at 6-7k and at 12k? Exists on both of our CSDs. Note GE's CSD plots are smoothed to hell.
I've never found singen and tone sweeps reliable. Mainly because they won't necessarily pick up sharp high Q peaks and our ears have variable frequency response based on volume. 1/3 octave noise works better IMO.
Thank you. Come to think of it, the graph here is really pretty much what I've been hearing, just shifted up a bit. I just never realized that those treble peaks were so prominent, but not necessarily painful or anything. Could also partially be because my earpads are getting rather worn and their overall shape has rounded a bit.
I was trying to figure which of my headphones was the "flattest" in the treble with sinegen. (conclusion: Yamaha YH-1, but I probably won't stick with those for long)
Is there any Windows program in particular that you would recommend for 1/3 octave noise?
