Diffusion and absorption panel (Abfuser): when to choose which solution? Introduction

A room can sound too “dull” with absorption alone, or too reflective without dampening. The solution often lies in the balance between diffusion and absorption. In this guide, we explain what a diffusion and absorption panel (hybrid/Abfuser) does, when to use it, and where to best place it.

Absorption vs. Diffusion: The Difference in 1 Minute
Absorption: converts sound energy into heat; shortens RT60; reduces echo/reverberation.
Diffusion: disperses reflections; maintains liveliness/spaciousness; prevents flutter without sounding “dead.”
Hybrid (Abfuser): combines controlled dampening with subtle dispersion.
When to Choose a Hybrid Panel (Abfuser)?
Mixing Rooms: Diffuse rear wall, dampen sides/first reflections.
Meeting Rooms: Natural speech, less “boxy” sound.
Restaurants: Quieter sound without the space feeling sterile. Small studios: absorption to eliminate first reflections, Abfuser at the rear for depth.
Placement: rules that always work
First reflections: primary absorption (near loudspeakers/listening position).
Rear wall at mixing position: Abfuser for width and depth.
Behind singers/presenters: Abfuser to maintain “room tone” without comb filtering.
Height & symmetry: ear height in the sitting position, respect the mirror axis.
How many panels do you need?
Small studio (10–15 m²): 2–4 Abfusers on the rear wall, plus 4–6 absorbers (S10) on the side/ceiling.
Office/meeting room (12–20 m²): 2–3 Abfusers opposite the speaking position, 4–6 absorbers distributed.
Restaurant area: 1–2 Abfusers per 10 m² as an accent, supplemented with ceiling or wall absorption. Material, design, and customization
PET front end + diffuser profile: aesthetic and effective.
Color and print (art panel style) available for branding/interior design.
Fire rating and installation: choose suitable hardware; an air gap can improve performance.
Common mistakes
Too much diffusion in a reverberant room (start with absorption).
Diffusers on first reflection points in small rooms (gives erratic response).
Asymmetrical placement around the listening position.
Conclusion and next step: A hybrid panel (Abfuser) gives you control and a natural feel. Start with absorption on first reflections and add Abfusers where you want spaciousness. Need advice? Contact us for a free proposal.
