Sound Absorption Treatment

Ceiling Sound Absorption

Ceilings are critical in managing large-area reverberation, especially in open-plan or high-volume spaces like offices, auditoriums, or studios.

Conceptual Insights:

• Sound Absorption ceiling panels prevent sound from bouncing repeatedly across hard overhead surfaces.
• Our Aphony Fibrette, Stretch Fabric Systems, and Elegant Tiles offer NRC values up to 1.0 with seamless architectural integration such as Clouds & Baffles.
• Concealed frame stretch ceilings combine visual elegance with high-performance acoustics, tested as per ISO 354.

Wall Sound Absorption

Walls are the largest reflective surfaces in most rooms and play a key role in controlling reverberation. Without proper sound absorption, walls contribute to flutter echoes and poor sound quality.

Conceptual Insights:

• Absorptive wall panels help reduce early and late reflections, enhancing speech clarity and reducing background noise buildup.
• Panel systems like Aphony Fibrette and Elegant Fabric Wall Panels can control mid-to-high frequency reflections and can be custom-mounted on Aluminium H-profiles or directly glued.
• NRC values for these systems range up to 0.74, and when combined with backing insulation like 1000 GSM Absorb Wool, can achieve NRCs up to 1.00.

Floor Absorption

Floors mainly transmit impact noise, such as footfall, dragging furniture, or machine vibrations — known as structure-borne sound.

Conceptual Insights:

• Acoustic floor treatment is less about reverberation and more about impact isolation.
• Systems include rubber or foam underlays, floating floors, or plywood-dampner composites.
• Our 12 mm Sound Dampner boards or underlay absorbent layers significantly reduce floor-to-floor noise transfer, especially when paired with vibration-isolated flooring systems.

Acoustic Facade Absorption

External building facades reflect environmental noise back into nearby areas or internal spaces through secondary paths like windows or curtain walls.

Conceptual Insights:

• Applying acoustic treatment to facades helps reduce reflected noise in dense urban areas.
• Wood Fibre Cement Composite panels or perforated barrier systems with absorbent infill act as first-line treatments.
• These also double as thermal insulation, improving overall building performance.

Acoustic Window

Windows allow not only light but also airborne sound into a space, compromising the acoustic envelope.

Conceptual Insights:

• Acoustic performance can be improved using double or secondary glazing, with an air gap in between.
• Internally, heavy drapes, acoustic blinds, or custom glass lamination help reduce transmission.
• We also recommend removable panel inserts backed with Absorb Wool for specialized installations (e.g., studios, control rooms).

Acoustic Door

Doors are often the weakest link in an acoustically treated space due to gaps and poor material density.

Conceptual Insights:

• Acoustic doors combine mass, damping, and airtight sealing to stop sound transmission.
• Treatments include solid-core leaf construction, perimeter seals, and automatic drop seals.
• For enhanced performance, sound-absorptive panels (such as fabric-covered foam) can be surface-mounted.
