What frequency can you go up to?

<< < (4/9) > >>

pwhodges:
I could hear the 14kHz clearly, which surprised me a little, as last time I tested it my limit was barely 12kHz.  (When I joined the BBC at age 23, they measured my limit as 17kHz.)

What I did notice is that even on bloody good headphones through an excellent interface there were clear artefacts audible to me on every higher signal.  In some cases these even sounded like a tone, but not the right one  (which presumably would have been louder if I could have heard it); but this possibly means that some care may be required to choose the right answer.

I'm interested by the number of people claiming to hear appreciably over 20kHz.  In my experience this is really unusual for people of age 20 or more.  I have been led to believe that there may be a correlation with suffering from asthma (indeed, the person I knew who could hear highest as a student - 23kHz - not merely suffered from asthma, but died as a result of an asthma attack at the age of 50).


--- Quote from: Dimmukane on 24 Mar 2011, 16:13 ---It's possible for people to lose specific frequencies or ranges of frequencies in their ears, and not necessarily in order of highest to lowest.  Which would explain being able to hear all of them but 19 kHz.

But that's also true to some extent of headphones or speakers...

pwhodges:
I expect that if you can hear them all you can tell that you're hearing the right thing really - so ignore me; I'm just feeling a bit jaded tonight (I've got a stinking cold).  I may only have heard the artefacts because I'd turned the volume up higher than should have been necessary, but I was struck by the fact that some of the artefacts were tones that sounded somewhat convincing except that I knew I couldn't possibly have heard the intended frequencies. 

I wanted to see what format the tones were being downloaded in, but the code has thoroughly obscured that.  Also to see if the frequencies were generated digitally, which is often done badly in a way that introduces artefacts.  But that's just me being nerdy.

Elysiana:
I tried this on my home speakers and found the same thing as you, Paul - I am hearing *something* at all the frequencies, but not the right tones. In fact, they sounded lower than some of the lower frequencies, so it's like I'm hearing some sort of harmonic instead.

WriterofAllWrongs:
18, which is really strange, because I live a pretty quiet life, so you'd think my hearing would be more intact.

whom:
Apparently mine is horrible.  I heard up to 14.
