Adjusting the SOUND FIELD program ■Room Size Simulation The sound emitted from a sound source is reflected many times between the left and right walls, ceiling, and floor before it reaches our ears. In a large room, the sound takes more time to bounce from one surface to another than in a smaller room. The ROOM parameter controls the spacing of early reflections to simulate the room size. The S indicator on the display signifies a small room, the L indicator signifies a large room and the middle point designates the standard room size. Room Size S Level Early reflections Room Size L Time I Level Early reflections ■Wall Material Simulation When sound is reflected by a wall made of soft material such as wood or a wall covered with a curtain, the high frequency components are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. The WALL parameter controls the level of high frequencies to simulate the wall material. The S indicator on the display signifies a soft wall, the H indicator signifies a hard wall, the middle point designates the standard wall made of wood. Wall S Level Early reflections Reverberation Frequency Low High Wall H Early reflections and reverberation Frequency Time Low High> 36
