DolbyHeadphone

Dolby Headphone is a system which provides a form of spatial sound image even with conventional stereo headphones.

Method of working:

When a stereo signal is reproduced via two loudspeakers set up in front of the listening position, the listener perceives the music to be spread out over the area between the right and left speakers, rather than directly from the two loudspeakers themselves.

The sound image appears in this way because of sound reflections: the sound from the front speakers reaches the ears directly, but is also reflected around the room, and by the listener’s shoulders and head.

The effect is amplified by the fact that the sound from the right-hand speaker reaches the left ear as well as the right ear (and vice versa), albeit with a slight delay.

The net result of these two processes is that it is possible to locate individual sound sources spread out across the front of the listening area.

If we attempt to reproduce the same signal using conventional headphones, the sound from each channel reaches the associated ear of the listener, but not the opposite ear. Furthermore the reflections in the room and the shoulder area of the listener simply do not occur.

The result of this is that the music reaches the listener directly from right and left, and therefore seems to come from inside the head rather than being spread out in front.

This is the reason why many people find headphone listening an unnatural experience.

Dolby Headphone is a process by which the music signal is processed to simulate the characteristics of music reproduction in a normal room; the result is that an approximation of the usual listening experience is possible even using headphones.

Dolby Headphone goes even further than this, and incorporates the rear channels which are present in 5.1 /

7.1material, providing a genuine cinema-like atmosphere even with conventional stereo headphones.

Three different types of room can be selected, so that the listener can match his or her personal preference to the type of music signal being reproduced:

-DH1 (reference room): small room with pronounced acoustic damping;

-DH2 (living room): small room, but with less pronounced damping;

-DH3 (large room): larger room with more diffuse sound distribution.
