Is this normal? I experience it on my home theater when listening to music and also on my IEMs with my iPod. Basically, if I turn up the music to loud levels (95-100 dB), it seems I cannot hear the highs as well as when at lower volumes. I did notice one thing though, when listening to music through my home theater, I turned it up really loud (100 dB or so) and put my fingers in my ears. The cymbals in the music were more pronounced and clearer. I guess this means it is not the audio setups and just my ears? By the way, is this normal?

Do you have room treatments or any form of DRC (digital room correction) and what's your set up speakers source receiver and room dimensions. Naturally drivers will compress and early reflections can have an effect on the timing of sound reaching your ears , I'm sure there are others here who can explain it in greater detail but there are some things you can do the two things mentioned above and then looking at the speakers( placed properly) and power on tap to drive them sufficiently to higher spls .

Does your system measure flat at all loudness levels now? Probably has more to do with how we hear certain frequencies as related to volume in any case; look up Fletcher Munson curves.

+1. if the system is EQ'd to sound right at low volume then it won't sound right at high volume. Dynamic EQ is one way around this issue.

Thanks for the replies.

My home theater consists of the following:

Display: Panasonic TH-42PW5
DVD Player: Pioneer DV610AV-K
A/V Receiver: Harman Kardon AVR 8500
Mains: Klipsch RF-7
Center: Klipsch RC-7
Surrounds: Klipsch RS-7
Subwoofer: Seaton Sound SubMersive

As you can see, it is still in the DVD ages. My A/V receiver does not have any EQ abilities built-in so I have no EQ. My room has no formal treatments. But I also notice the same issue on my Sony XBA-3 IEMs when connected to my 5th generation iPod touch. Maybe I used the wrong words but I can still hear the highs, it is just that they don't sound as "delicate" or prominent (or even as airy) as when at lower volumes. Basically, I can hear more detail in the highs at lower volumes than at higher volumes.
