Yamaha HTR-5835 owner manual 1Press AMP, • Elements of a sound field, Reverberations

What really creates the rich, fidl tones of a live instrument

are the multiple reflections l}om the walls of the room. In addition to making the sound "live", these reflections enable us to tell where the player is situated, and the size and shape of the room in which we are sitting.

• Elements of a sound field

In any environment, in addition to the direct sound coming

straight to our ears from the player's instrument, there are

two distinct types of sound reflections that combine to make up the sound field:

Early reflections

Reflected sounds reach our ears extremely rapidly (50 ms

100 ms after the direct sound), after reflecting fi'om one

surface only for example, from the ceiling or a wall.

Early reflections actually add clarity to the direct sound.

Reverberations

These are caused by reflections from more than one

surl:ace walls, ceiling, the back of the room so

numerous that they merge together to form a continuous

sonic "afterglow". They are non-directional, and lessen the clarity of the direct sound.

Direct sound, early reflections and subsequent

reverberation taken together help us to determine the subjective size and shape of the room, and it is this

infommtion that the digital sound field processor

reproduces in order to create sound fields.

If you could create the appropriate early reflections and

subsequent reverberations in your listening room, you would be able to create your own listening environment.

The acoustics in your room could be changed to those of a

concert hall, a dance floor, or virtually any size room at all. This ability to create sound fields at will is exactly

what YAMAHA has done with the digital sound field processor.

You can enjoy good quality sound with the factory preset

parameters. Although you do not have to change the initial

settings, you can change some of the parameters to better suit the input source or your listening room.
