The purpose of architectural acoustics is: To reduce the reverberation time (commonly known as "echo"). This result is reached by absorbing reflected sound. 
The reverberation time is:
The time between emission of a sound and the complete interruption of its source.
Ideal reverberation times vary according to the volume and usage of the area concerned.
Effects of a too long reverberation time on the acoustics of a room: When speaking, a long reverberation time causes an overlap between successive syllables, with a masking effect that reduces clarity. In the case of music, persistence of low frequencies causes the sounds to melt together, with a confused or indistinct effect. Effects of a too short reverberation time on the acoustics of a room: If the reverberation time is too short, the impression is that of a "dry" sound, unsupported by the environment. Further, a short reverberation time in a large area can cause the sound volume to be too low at the far end of the room, as the sound reflections that otherwise would sustain volume are not present.
