If your primary problem is echoing, reverberation, or excessive ambient without privacy concerns, passive treatment is likely sufficient.

Most well-designed offices benefit from both: passive treatment on the open floor to reduce ambient, and enclosed pods for the work types that require certified speech privacy.
