"Grazing sound fields, which exist mainly in the mid and high frequencies, consist of sound energy developed in a plane parallel to a sound absorbing surface (normally the ceiling). The reverberation time in a room is mainly determined by the grazing sound fields. This means, in practice, that the reverberation time is considerably longer than the value calculated for diffuse sound fields." A Sabine-képlethez (is) kapcsolódik.
