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.
