Reverberance
• Linked to the speed at which sound energy disappears in a room
Long reverberation

Speech clarity
• Concerns the quality of speech transfer to the listener
Unclear

Auditory strength
• The level at which we experience sound
High level
Low level

Spatial decay
• The sound level decreases as the distance to the sound source increases
Speech at 1 m distance
Speech at 4 m distance
Speech at 8 m distance

Crucial points
• Size, shape, surfaces and furnishing
• More absorption gives lower sound level
• Reverberation time is not enough
• We need four quality aspects
• People, room, activity
