Headphones - in head problem
Thanks for the suggestions. I have followed the links and browsed
further.
It would appear that making recordings to be played back on headphones
can eliminate the mildly unpleasant, "in head" sensation. The most
striking example comes from following Rich's link to the Dolby pages
and listening to the racing car example (it used to be trains with
stereo if I recall correctly). However, this is a promotional example
and may not be representative of listening to music. For example, the
source of the sound is constantly moving around rather than remaining
fixed and this may encourage the brain to place the source at a
distance. In addition, if the musical source is fixed and the head is
moved slightly this will move the source in a way that is strange. Will
this pull the sound back into the head?
Unfortunately, I have a mixture stereo and mono music with no
recordings especially for headphones. I did find a couple of files of
raw versus "crossfeed" processed. The in head sensation was marginally
reduced with the processing but probably not enough to be worth while.
There was a loss of clarity as one would expect but no sense of a real
room. In truth part of the processing sounded odd and unnatural. On
balance I preferred the unprocessed files. The combination of effects
used in the files was not known and it may be possible to do better.
However, I suspect that there is no standard set of processing
parameters that is going to work well for all music because of
different microphone arrangements leading to summing left and right
differently and, probably, in a frequency dependent manner if phase
varies with frequency. Can anyone confirm significant positive results
using crossfeed processing?
Thanks again for the suggestions but I think I would still like to hear
from anyone who has experience of the in-headness of headphones like
the AKG K1000, the box-like Stax headphones and the Jecklin/Ergo
headphones which still seem to be around although not with
electrostatic transducers.
