Quote:   That's a good question. There's a fair amount of literature about detectability of group delay, but in general the threshold varies from 1ms (around 2-4 kHz) to few ms (at lowest frequencies). And of course, 0.1ms doesn't make much different at lower frequencies, or at any...

Hi,    I've been there many times... As long as the sound is somewhat decent, you get used to different sound "signatures" quite fast, and then any change will sound just plain bad, until you get used to it. That's pretty much how our brain (hearing) works.   I need to evaluate different...

  High frequencies have nothing to do with low frequency performance, nor are they needed for a detailed low frequency reproduction. This is naturally assuming that there are now major non-linearities in the system. However, in music there rarely is such material that would only have low...

Quote: But, you are hearing both the flattening and the increase in SPL, although only the latter is measurable. Isn't that what the original question was about, are there things that we can hear but are not measurable. What if you'd hear just the increased SPL version of the sound. How...

Quote:   Could be that I'm misunterstanding the original question, or we're just trying to explain different things.   However, to comment your post.. The point I was trying to make was, that what you hear (or imagine, like you put it) doesn't necessarily correspond to the...

  Quote:   Hearing is measuring, in one sense. But, sound perception is not the direct outcome of this 'ear measurement'. Your brain makes hard work trying to make some sense out of this measurement data. Your brain has spend years on learning to interpret this data, and whenever you...

Quote:   Yes, you are right about SPL level getting higher when you turn up the volume. And certainly, you can measure this. But, when you increase the volume, the lowest frequencies, and also the highest frequencies, in music are perceived to get louder than the mid frequencies. This...

Hi,    I don't have those particular headphones so I can't exactly say what would happen. Though, open headphones are designed to be open, and closing the back most probably has some effect, e.g., resonances move, bass gets thinner.. However, the material that you mentioned is not that...

One easy way to monitor your hearing is to keep track on the volume levels on your amp (or whatever is your listening setup). If you see a trend that you need (constantly) more volume compared to past, then that could be one sign or a warning of a hearing loss. But if you stay happy with your...

Many of the psychoacoustic related phenomena are not measurable. For example, perceived frequency balance is level dependent, playing louder makes you hear more bass (compared to mid frequencies) but this you cannot measure with a microphone. Missing fundamental -effect is another example. If...

I believe you are confusing three different things, hearing threshold, equal loudness and head related transfer functions (HRTF). Hearing threshold refers to SPL where certain sound is audible. This varies between frequencies. Human hearing is more sensitive at mid frequencies, and less...
