Reducing reverberation noise for an indoor swimming pool complex

Aquatic centres and indoor swimming pools are known for their acoustic design challenges.

Acoustic materials are commonly incorporated into the architectural design of the building to ensure comfort for users and staff by absorbing the noise of users along with that generated by plant & equipment.

Acoustic materials must meet strict requirements and withstand the heat/humidity and the impacts of chlorine and other pool chemicals.  Two of the trusted and proven products are as follows:

  • Megasorber FM acoustic panels.  It is extremely lightweight and has a special thermoset acoustic foam combined with water-repellent, tough and durable, non-combustible Soundmesh® G8 facing.  Acoustic performance is NRC up to 1.0.
  • Megasorber P acoustic panel. It combines the water-repellent, non-combustible Soundmesh® G8 with hydrophobic polyester fibre.  Acoustic performance is NRC up to 1.0.

Megasorber’s water-repellent Soundmesh® G8 limits water ingress into the panels, providing an effective solution for such humid environments.  Both Megasorber FM and Megasorber P acoustic absorption panels are excellent candidates for reverberation control in the harsh environments of aquatic centres and swimming pools.

A few examples from previously completed projects

Megasorber’s FM range of acoustic absorption panels perfectly suits the harsh environments of aquatic centres and swimming pools.

The lightweight design gives architects and designers the freedom to tailor the look of the finish while still being easy to install.

Aquatic Centres

These acoustic panels offer architects and designers the freedom to tailor the look of the finish and are easy to install.   With a range of colours available, the design possibilities are endless!

Installation methods include:

  • Direct fix to roof panels, especially the insulated roof panels such as Kingspan and so on.
  • Direct-fix onto concrete soffits.
  • Installation between purlins.
  • Ceiling grids.
  • Insert behind decorative perforated panels, timber or aluminium battens.
  • As an example, architectural wave patterns or acoustic blades are shown on the right.

Acoustic backings

for perforated/slotted panels and timber or aluminium battens
  • Megasorber Soundmesh® G8 and G8A are acoustically tuned to convert slotted panels, perforated panels or any other decorative panels into acoustic panels. Furthermore, it is also attached to the back of timber or aluminium battens.  Combined with an air gap, the acoustic performance is up to NRC 0.80.

  • Megasorber PN is a thin acoustic board that can be easily inserted or thatched onto the back of timber or aluminium battens. The acoustic performance is NRC up to 0.80 when combined with an air gap.

  • Megasorber Wavebreaker has water-repellent Soundmesh® G8 on both sides of the acoustic panels.  It is a patented product that provides superior acoustic performance with NRC up to 1.0 with a plenum.  It is installed between purlins, behind perforated or slotted panels, and behind aluminium or timber battens.

Demonstration of echo noise reduction

A scout hall with polished floorboards, plasterboard ceiling and walls, – these surfaces are highly reflective to sound.  The hall was very echoey, causing poor speech intelligibility.  This newly constructed hall was deemed unusable by the scout group.  To reduce the reverberation, 50mm thick Megasorber acoustic panels were installed on the ceiling and on the walls.

Demonstration of fire resistance

Megasorber FM is inherently fire-resistant and has Building Code Australia (BCA) Group 1 fire rating as per AS 5637.1-2015 and ISO 5660 Group 1 fire classification.

No ignition, melting, dripping or spread of flame when exposed to fire.  A demonstration video is shown below.
