Reducing Echo / Reverberation

Megasorber’s range of acoustic absorption materials is ideally suited to reduce reverberation in a variety of applications to provide superior speech intelligibility

From halls, churches and stadiums to offices and video-conferencing rooms, restaurants, cafes and bars to residential and studio applications, Megasorber FM panels assist in creating a comfortable acoustic environment and superior speech intelligibility.

If there are many hard surfaces in a room, the ‘noise’ and soundwaves are reflected, bounce around, echo and reverberate. This noise energy builds up and gets louder, which is a major source of discomfort for occupants of the room.

Megasorber acoustic absorption panels can be installed onto the ceiling – either directly fixed to or as hanging baffles – and walls to reduce reverberation and improve the room’s acoustics and speech intelligibility.

Recommended Treatment

We recommend lining the ceiling and walls with Megasorber’s FM range of acoustic absorption panels.

Key features of Megaosrber FM acoustic panel

Megasorber FM has superior acoustic performance, utilising a patented sound absorption technology.  It has a Soundmesh G8 facing, a non-combutible woven fabric that is tough and durable.  This facing is easy to clean – any dirt marks or finger marks can be removed with Megasorber Clean M8 block and water.

Combined with an express finish, it is one of the most cost-effective solutions for reverberation control, especially for large spaces and halls.

The panels can be easily adhered to the ceiling and tops of the walls with Megasorber A200 adhesive.

Megasorber FM panels can be cut into different sizes & shapes and have a range of finishing colours depending on your preferred aesthetic.

Finishing options include using a shadow line finish or using a trim around the panel edges. Panels can be custom-cut to size and shape to fit in with your project requirements

In office and school settings, Megasorber FM25 is typically sufficient. In restaurants, bars, halls, and larger public spaces, Megasorber FM50 panels are recommended.  Alternatively, Megasorber WFM provides a larger range of colours and finish patterns.

How much absorption do I need?

The general rule of thumb is to treat at least 30-40% (the more, the better) of the total surface area with Megasorber FM panels.

Here’s how to calculate the required panel coverage:

Calculate the surface area of all walls, ceilings, and floors.
Note – only count the floor if it has a hard surface like floorboards/tiles etc. You need to treat 30-40% of this total surface area.

Example: For a room that is 6m x 3m x 2.7m (height) with a tile or timber floor…

Walls: 6m x 2.7m (x2)
Walls: 3m x 2.7m (x2)
Ceiling: 6m x 3m
Floor: 6m x 3m

Total Surface Area: 85m2

The area for treatment on the above should therefore be 25 to 34m2, which is around 9 to 12 panels of 1.2m x 2.4m.
