Concrete acoustic panel MH
The MH sound-absorbing panel consists of a double layer: a reinforced concrete structural layer and a sound-absorbing porous concrete layer.
The panels are supplied in the natural colour of the concrete, and may be coloured or decorated using patterns or shapes.

Panel Morphology
- Material: CONCRETE
- Is it absorbent for both sides?:
- Assembly: SLIDING
Components
- Outer sides (exposed to noise): Porous concrete layer. Its ribbed geometry and porous material give the panel its absorption properties. It is made of porous concrete with ø 3 6mm gravel.
- Inner side: Structural layer of HA-25 or HA-30 concrete up to 12 mm thick, reinforced with B500S steel mesh.
Benefits
- Good sound absorption capacity.
- Due to its mass, concrete has excellent sound insulation capacity.
- Structural durability.
- Adaptation to the landscape and architectural constraints of each site due to its discreet appearance and the possibility of being painted in different colours.
- Material with low environmental impact, recyclable and zero waste.
Acoustic features
- According to Standard EN 1793-1, sound absorption index DLα (A2) is obtained.
- According to Standard EN 1793-2, sound insulation index DLR (B3) is obtained.
