Reference diffuse-field frequency response curve
The individually measured diffuse-field frequency response curve for
your HD 800 S headphones can be found on the supplied USB flash
drive. The reference diffuse-field frequency response curve can be found
on the inside cover page.
What is the diffuse-field frequency response curve?
In an anechoic
chamber, 8 highly linear loudspeakers emit noise signals independently
of each other. In the central area of the chamber, the various sound
data meet and are superimposed on each other to form a diffuse field,
in which it is no longer possible to determine from which direction the
sound is coming.
This noise is then varied in distances of a third and reproduced
alternately over the speakers and the headphones to be measured.
A large number of test persons then evaluate the difference in volume
between the room noise and the noise in the headphones.
The ideal state is when the volume impression between the diffuse field
and the headphones is the same. Diffuse-field equalized headphones
provide a clearly more spatial impression and make it easier to
determine whether sounds are coming from the front or rear. Put simply,
the sound events take place outside the head and are not confined to the
space between the ears.
