Reverberation times and reverberation levels

Reverberation times and reverberation levels are the statistical parame¬ters of the stochastical sound field in a room. Their theoretically derived and practically measured properties are discussed. Reverberation times and rever¬beration levels are place dependent, they are also to a certain extent influenced by the shape of the hall and the distribution of the absorption in it. This influen¬ce is however limited as regards the reverberation times.
