Comparison of Elitexa Sponge and Traditional Sponges

  • Density: the Elitexa sponge has a significant advantage in density. While conventional sponges have an average density of only 20kg/m³, the Elitexa sponge exceeds this by a factor of ten, with a density of 140kg/m³.
  • Sound insulation and sound absorption: This higher density means a radical difference in sound barrier and sound absorption. A dense sponge absorbs and blocks sound much more effectively than a normal sponge.
  • Frequency range. This can be a problem in studios or home cinemas where clarity of sound is important. Conversely, Elitexa sponges can effectively absorb sounds from as low as 40Hz.
  • Structure. This structure allows the sponge to keep sound from passing through and absorbs most of the sound that does pass through.

These properties make Elitexa sponge particularly suitable for situations where precise sound reproduction and effective sound isolation are essential. Whether in a studio, a home cinema or even a public space, Elitexa sponge is an excellent choice for creating the desired acoustic environment.

Soundproofing Sponge Functions

Acoustic Applications:

  • As interior wall cladding: another popular use is as interior wall cladding, creating a cosy atmosphere and improving the sound quality.
  • As an acoustic panel: can also be used as a home-made acoustic panel, providing a practical solution for fine-tuning the sound.
  • Wall-mounted: ideal if you don’t want to redecorate the room. It is easy to apply thanks to the self-adhesive layer, and the surface can be wallpapered or glued. The high density sponge can provide up to 60dB sound absorption.
  • Applications:
    • In studios: where clarity of sound is key.
    • In offices: where a quiet environment promotes concentration.
    • In the home: for example in bedrooms or living rooms where quiet and calm are important.
    • In public places: such as restaurants and cafés, where a pleasant atmosphere is the goal.

Colours may vary within a single order.
