Soundproofing Material Property:

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, i.e. 200kg/m³.
  • Sound insulation and sound absorption: This higher density means a radical difference in sound insulation 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:

  • Installation behind plasterboard: the Sound Absorbing Sponge works great when installed behind plasterboard, significantly improving the sound insulation and sound barrier of the room.
  • As an internal wall covering: Another popular use is as an interior wall covering, which creates a cosy atmosphere and improves sound insulation.
  • As an acoustic panel: can also be used as a home-made acoustic panel, providing a practical solution for fine-tuning the sound.
  • As a parquet or carpet underlay: It can also be a great choice for soundproofing under flooring, reducing impact noise and sounds from below. The hardness of the underlay means that it will not sink in, so the gait remains stable whether you use it under parquet or carpet.
  • For parquet or carpet underlay: Ideal if you don’t want to redecorate the room. It’s 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.
