STP Acoustic Block Sound-absorbing block for cavity filling and low-frequency noise reduction

STP Acoustic Block is a sound-absorbing material designed for filling structural cavities inside the vehicle, where traditional materials cannot be applied. Made of visco-elastic polyurethane foam, it is specifically designed to reduce noise and vibrations at low frequency inside empty spaces such as door pillars, fenders and cavities. It is a technical solution also used in the OEM field on high-end vehicles.

How a sound-absorbing block for cavities works

Inside the body there are empty areas that:

  • amplify vibrations
  • function as resonance chambers
  • propagate low-frequency noise

STP Acoustic Block works differently compared to panels:

  • physically fills the cavity
  • absorbs acoustic energy
  • stops wave propagation
  • reduces internal resonance

The result is:

  • less "muffled" and deep noises
  • reduction of structural vibrations
  • greater acoustic comfort

When to use it and where to apply it

Ideal applications:

  • cavities between body and fenders
  • pillars (A, B, C)
  • empty spaces in the trunk
  • structural gaps

Typical use:

  • low-frequency noise treatment
  • elimination of internal resonance
  • improved comfort on long journeys

Important: Should not be used in areas exposed to direct moisture.

Installation

Procedure:

  1. identify the cavity to be treated
  2. verify absence of moisture
  3. insert the block into the space
  4. adjust if necessary

Does not require adhesive:

  • remains in position by compression
  • adapts to the shape of the cavity

STP Acoustic Block is a technical solution designed to treat vehicle body cavities, reducing noise and vibrations that traditional materials cannot manage. Thanks to its ability to absorb low frequencies and fill empty spaces, it represents an advanced complement in soundproofing systems, ideal for achieving real acoustic comfort improvement at the most critical points of the vehicle.
