Dolby Headphone

A brief introduction

Dolby Digital and DTS provide discrete left and right surround channels,
for more precise localization of sound and a more convincing, realistic
ambience. Discrete means that each channel contains its own particular
audio information and plays a unique role in creating a realistic surround
sound experience.

Up until now all this was reserved to speaker set-ups, but thanks to
Dolby Headphone, the ultimate experience in home theatre surround with
five (left, right, centre, rear-left and rear-right) discrete channels of digital
sound quality is now also available to headphones.

Dolby Headphone is a revolutionary signal processing system that works
not only with multi channel audio but also with conventional stereo signals.
In case of multi channel audio signals, Dolby Headphone technology will
process these signals in such a way that you will experience the sound
through your headphone as if it were coming from an actual five speaker
home entertainment set-up. And even when listening to conventional stereo
signals, Dolby Headphone will give you a much more natural and less
fatiguing listening experience, equivalent to a good two-speaker playback
system in a room with good acoustics.

Dolby Headphone technology can model the sound of a playback system in
up to three different listening environments, based on acoustic
measurements of real rooms:

• DH1 is a small, well-damped room appropriate for both movies and

music-only recordings.

• DH2 is a more acoustically live room particularly suited to music

listening, but also great for movies.

• DH3 is a larger room, more like a concert hall or movie theatre.

You can easily switch between these room modes and select whichever one
suits the particular program material and your own preferences.

Advanced technologies used in HP 1500

The HP1500 makes use of several advanced technologies.

Principle of determining the direction of sound

People can determine the localization of sounds through the perception of
differences in intensity – so called Interaural Intensity Difference (IID) – and
through time differences – so called Interaural Time Difference (ITD).

IID is about the fact of sounds being louder as they are closer to the ear
and being louder in case they have a non-obstructed path to the ear.

ITD is about the fact that in most cases sounds will arrive earlier in time at
one ear than at the other.

In fact it is the environment itself that greatly impacts the sound before it
reaches our ears. Reflections and absorption all will influence the sense of
distance and direction we associate with a sound.

Combining IID and ITD will allow the brain to determine the direction of
sounds only in a rough way. It is in through the combination of IID and ITD
and the way sounds are filtered because of the structure of the pinna
– the outer ear – that allows to brain to accurately localise sounds.

• Depending on how a sound wave hits the pinna, it will be emphasized
or suppressed.

• Depending on how a sound wave hits the pinna, reflections within the
pinna are created, altering the phase relationship within the spectrum of
the sound wave.

• And also: higher frequencies are more affected by the pinna than lower
frequencies.That’s why our brain can easily locate higher frequencies,
rather than lower frequencies.

ENGLISH 7

0912HP_EU 09-12-2003 12:12 Pagina 7

ENGLISH8

If we wish to reproduce all those effects through an audio system, than we
need to take IID, ITD, pinna effects, room impulse response, etc. into
account.That is where Head-Related Transfer Functions (HRTF) come into
play.

An HRTF is a mathematical equation that describes how a sound is effected
when travelling from its source to our ears.

There are several ways to synthesise an HRTF. The most common way to
measure an HRTF makes use of placing tiny microphones in a listener’s ears.

Every person has its unique HRTF. However, we can identify crucial parts in
an HRTF that are responsible for localization of sound as if this sound
would be radiated by a typical home cinema speaker set-up.
When these parts are synthesized in an optimal way, a typical 5 speaker set­up listening experience is created.

HRTFs are implemented in real-time Digital Signal Processors (DSP) and
will then be applied to audio signals in order to reproduce "spatial" cues, i.e.
create a sense of directionality.

It is through these techniques that Philips is able to bring you a home
cinema experience through a headphone that is as real as when you would
be listening to an actual 5.1 speaker set-up.

0912HP_EU 09-12-2003 12:12 Pagina 8

Automatic Audio Signal Routing

The Automatic Audio Signal Routing (AASR) feature of the HP 1500
basestation allows for audio sources to be connected to its audio inputs and
at the same time it can pass those same audio signals on to – for example –
your Home Cinema receiver. This allows for permanent audio connections
to be made without the need for swapping cables.Whether you want to
listen to your headphone or your existing speaker set-up, it no longer
involves tiresome swapping of cables: the choice is yours at the flick of a
switch.

Intelligent user interface

After a digital analysis of the audio input signal the display will indicate which
sound processing features can be activated. No more frustrating pressing of
all buttons. Just read the display and select out of the active sound menus.

Headphone construction

The headphone’s semi-open construction will benefit the transparency of
the sound.This will make you experience your favourite tracks under even
more realistic conditions.

Neodymium magnets

Neodymium is the strongest magnet material available, which optimises the
behaviour of the speaker coil for increased sound pressure levels and a
more powerful bass response. All this at the lowest possible levels of
distortion.
