Disclaimers

  • All calculations are based on the basic acoustical theory of Sabine’s Formula using the recommended guidelines of room reverberation time(s).
  • This is a simplified model that provides fairly accurate results but it is for general reference only.
  • Please note that wall positions and room geometry can affect the reverberation time.
  • Calculations are based on an empty space with no furnishings or people. Furniture, plants, rugs and people tend to reduce reverberation time.
