Understanding the Different Types of Acoustical Treatments – Absorption

In this livestream, we go over the various types of acoustical room treatments with resident expert Anthony Grimani. We discuss how to acoustically treat a room and where to locate treatments along with things you should NOT do. Various acoustical treatment types are discussed with this episode focusing on absorption. Diffusion, reflectors, and bass traps and their effectiveness are briefly discussed in this episode but will be expanded upon in future talks.

A “well-treated” room has clear direct sound from speakers, and a nearby, smoothly dispersed field.

Acoustics recipe:

  • 15% absorptive surface
  • Even distribution
  • Lower reflected energy


  • 20% Diffusive surface
  • 2D in front; 3D in rear (improves spaciousness)


  • Bass absorption in corners


  • Treat ceiling (veritcal reflections “narrow” the soundfield)
