    In a different thread I linked to a scientific paper which demonstrated the ability of humans to be affected by inaudible high frequency sounds.

    Here is the paper again.

    I'm sure that, over time, 'science' will keep catching up with various phenomena. The gap between 'objectivity' and 'subjectivity' will increasingly narrow but will always be there. Thankfully as otherwise Forums will cease to have a purpose.

    That is the key point, Edward! Scientific facts, when applied to audio, are rarely a 'done deal', but simply a reflection of our current learning. And that's the crucial point: we're continually on a learning curve, which is why it pisses me off when folk apply science to audio in such as 'black and white' way, simply to try and 'prove' a point

    It's also why that, ultimately, I'll always trust my senses and gut instincts in audio, no matter what the supposed 'scientific facts' say to the contrary, and that approach will only change, as you say, when/if science catches up with what's revealed by the highly-attuned auditory senses we were born with!

    Hi Mr C

    I have none! I really don't know anything like enough about this subject.

    What I know is mainly practical listening based so when we get into the scientific explanation of sound, I am lost lol

    Oh dear
    I see that Nyquist Denial is here again.
    I'll just leave it alone this time and listen to some music.

    Nothing to do with your posts here, Marco.

    Just someone saying that finer sampling under the Nyquist frequency gives better accuracy.
    It doesn't, the musical waveform can already be reconstructed accurately.
    This has been addressed several times on AOS, but it keeps coming back again.

    Some of the first work on sampling theory was undertaken by Shannon whilst working at the Bell Telephone Laboratories. He showed that to accurately sample a sine wave having a particular frequency, the sampling rate has to be double that frequency. The sampling frequency is also known as the Nyquist rate, or frequency.

    Nyquist was a mathematician (also working at Bell Labs), who amongst other things, undertook the analysis of electronic thermal noise, as described by Johnson (it is thus also referred to as Johnson noise), and provided the formula for the mean square thermal noise voltage of a resistor of value R, at a temperature [I]T[/T] over a bandwidth B: 4kTRB.
