soni TRAPEZ is a sound-absorbing PUR foam with a distinctive, trapezoidal surface. The profile shape increases the effective surface area and thus improves absorption, especially in the mid and high frequency ranges – where speech, music, and room reverberation occur.
The material is flame-retardant (B1 according to DIN 4102), versatile, and easy to install with adhesive or double-sided tape. Applications include recording studios, voice-over booths, home theaters, gaming rooms, and music rooms.
Optimize sound – design spaces
With soni TRAPEZ, you bring studio quality to your walls. The trapezoidal structure is acoustically efficient and visually modern – perfect for anyone who wants to minimize disruptive room reflections without compromising the room's aesthetics.
Why soundproofing

Good sound insulation ensures a higher quality of life – whether at home, in the office or in sensitive areas such as medical practices or hotels.

Sound-absorbing and sound-insulating materials reduce disruptive noise, protect privacy and create a more pleasant atmosphere.

The right products make all the difference: Depending on the room, location and noise source, there are materials that reflect, absorb or block sound – or even all at the same time.
