Product Description

Manufactured from high quality EPS (Expanded Polystyrene), the Trap Fuser is a unidirectional panel that controls sound reflections in two different ways – absorption and diffusion. Its hybrid structure allows sound energy to either be trapped in the cavities, or scattered by the plain surfaces. Usually applied for the treatment of mid or high frequencies, the Trap Fuser panel represents true acoustic science development. Designed for a range of frequencies between 630 Hz to 5 KHz.

In many practical applications, especially those that require a large area of diffusion treatment, it is common to repeat a same diffuser, so as to introduce periodicity into a sequence. This will concentrate the reflection energy in the diffraction orders of the grating and result in a narrower diffusion pattern. The innovation with the Trap Fuser lies in the freedom to position the panel’s two halves and create random sequences.

By rotating these diffusers in different directions, you can achieve combinations of patterns that are not only appealing to the eye but also extremely efficient when the aim is diffusing sound in a particular area. In fact, studies show that there are specific patterns that optimize diffusion and acoustic technicians can recommend which pattern works best, given the requirements of the area.

Assuming positions 0 and 1, the panels can be positioned according to simple binary sequences, with variations of 180°. Another possible combination is making 90° variations of the panels, thus transforming a one dimensional (1D) panel into a two dimensional (2D) system.

Applications: It can be used in various places like Recording and Broadcast Studios, Post Production Studios, Listening Rooms, Conference and Teleconference Rooms, Lecture Halls, Distance Learning Rooms, Public Spaces, Auditoriums, Performance Spaces, etc.

Apply Flexi Glue Ultra on the back of the acoustic panel, near the edges. Do not wait longer than 10 minutes after applying the glue to attach the panel to the wall. (As shown in image 1).

Place the panel on the suitably chose position on the wall. Once in the desired place, press firmly against the wall for 15 seconds. (As shown in image 2).

To ensure that you maximise the strength of the glue, don’t make any adjustments to the panel after bonding.

Please Note: Level, Flexi Glue Ultra, Measuring Tape are NOT INCLUDED.


Wall and ceiling surfaces should be examined prior to installation, ensuring they are clean, smooth, and dry. If you have unpainted gypsum board surfaces, these should be primed with a drywall primer (or another material manufactured especially for the purpose), to equalize the absorption between the gypsum board face paper, joint compound, and skin coating materials. You should then apply the paint, and allow air circulation in order to dry the paint within the time frame specified by the paint manufacturer. Please ensure the paint is dry before installing the acoustic panel. Make sure the room has all the necessary conditions to receive the acoustic panels. After you apply the glue on the back of each acoustic panel, please ensure you hold the acoustic panel against the wall the required time (mentioned above), and ensure it stays fixed in place. This method is also applicable to ceiling installations.
