MUTE+^® Sound absorbers for walls and ceilings

The Lindner broadband absorber covers the entire frequency spectrum relevant to room acoustics, whereas the Lindner low-frequency absorber is specifically designed for sound absorption in the low-frequency range.

Yes. Both the element frame and the insulating core of our absorbers are made from non-combustible materials. This makes them suitable for use in environments where non-combustibility is required in accordance with fire protection regulations.

Yes. The absorber elements can be powder-coated in any available RAL colour. The standard finish offered by Lindner is RAL 9010 or RAL 9016.

Low-frequency absorption is achieved by means of a freely vibrating aluminium plate integrated within the element. The Lindner low-frequency absorber must be installed with a 20 mm gap between the absorber and the solid surface behind it. This rear cavity allows sound to enter the element, where it is attenuated by the insulating material and causes the freely mounted aluminium membrane to vibrate, resulting in efficient low-frequency sound absorption.

Depending on the mounting surface – wall or ceiling – the designated suspension profiles are installed at the specified spacing.
The absorber elements are pre-equipped during production with the appropriate counterpart fittings, allowing for a simple and secure installation by hooking the elements into the profiles on site.
