Room Absorption Characteristics

The table below gives mean sound absorption coefficient - λ_m - values and reverberation time - T_a - for some typical rooms.

The mean sound absorption coefficient should be calculated when more accurate values are needed.

The diagram below can be used to determine the sound absorption of rooms at different sizes and with different characteristics.
