E-96DIGITAL SOUND FIELD PROCESSING (DSP)Understanding sound fieldsA sound field is defined as the “characteristic sound reflections of a particular space”. Inconcert halls and other music venues, we hear early reflections and reverberations as wellas the direct sound produced by the artist(s). The variations in the early reflections andother reverberations among the different music venues is what gives each venue its specialand recognizable sound quality.Yamaha sent teams of sound engineers all around the world to measure the soundreflections of famous concert halls and music venues, and collect detailed sound fieldinformation such as the direction, strength, range, and delay time of those reflections.Then we stored this enormous amount of data in the ROM chips of this unit. Early reflectionsReflected sounds reach our ears extremely rapidly (50 ms – 80 ms after the direct sound), after reflecting from one surface only — forexample, from the ceiling or a wall. These reflections provide vital information to our ears. Early reflections actually add clarity to the directsound. ReverberationsThese are caused by reflections from more than one surface — walls, ceiling, the back of the room — so numerous that they merge togetherto form a continuous sonic “afterglow”. They are non-directional, and lessen the clarity of the direct sound.Reflected sounds image
