The direct sound is the sound component in a closed room that first arrives at the listening or measuring point without having experienced sound reflections in the meantime. The incidence of the first wave front as direct sound is decisive for the determination of direction, i.e. the localisation of a sound source by hearing with both our ears (law of the first wave front, precedence effect).
