2-7. DESCRIPTIONS OF THE SOUND FIELD PROGRAMS

The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind that most of these are

precise digital recreations of actual acoustic environments. The data for them was recorded at the locations described using sophisticated sound

field measurement equipment.

The channel level balance between the left rear effect channel and the right rear effect channel may be different depending on the sound

field you are listening to. This is due to the fact that most of these are recreations of actual acoustic environments.

1. CONCERT HALL 1

Hall A in Europe:

Hall B in Europe:

This is a large fan-shaped concert hall in

Munich which has approximately 2500

seats. Almost the whole interior is made of

wood. There is relatively little reflection

from the right and left walls, and sounds

spread finely and beautifully.

This is a large shoe-box type concert hall

with approximately 2500 seats. Almost the

whole interior except the ceiling is made of

wood, including mahogany reflective

panels. Special reflective paneling above

the stage produces strong frontal

reflections which tend to reinforce the

direct sound from the stage. This hall has a

very solid, powerful sound.

2. CONCERT HALL 2

Hall C in Europe:

A classic shoe-box type concert hall with

approximately 1700 seats. Pillars and

ornate carvings create extremely complex

reflections. Those reflections and the

reflections from all directions of the hall

produce a very full, rich sound.

Hall D in U.S.A.:

This is a large 2600-seat concert hall in the

United States which features a fairly

traditional European design. The interior is

relatively simple, suggesting an American

taste. Sound of the middle and high

frequencies are richly and beautifully

reproduced.
