Chapter 4.0 Treatment placement
4.3 How much material should you use?
The amount of treatment material a space requires varies from case to case. Too little treatment material can undermine your acoustic performance goals. Too much can mean unnecessary expenses and space usage.
Calculating the reverberation time of a space can give you an idea of how much treatment material is needed. Additionally, most treatment suppliers offer calculators that allow you to estimate treatment needs based on space dimensions and other variables. Consulting with a professional acoustician is also highly advisable.
