When you release your creativity in a brainstorming session it is a lively activity, often with people walking around and two or more people speaking at the same time. The dynamic activity is usually done in a closed space with a flexible interior, sort of a “cool meeting room”.
To avoid echoes, support communication (speech clarity) and prevent sound from entering and leaving the space.
Sound insulation, a sound absorbing ceiling or free-hanging units, and wall absorbers covering at least one wall, but preferably two adjacent walls.
