Managing Noise, Vibration and Harshness in Automotive Interiors

CONTACT A 3M EXPERT

You are about to discover that for auto interiors, quiet is a great place to start

The sound inside the vehicle is a big factor affecting passenger experience, as passenger experience becomes one of the biggest factors in automotive design. Sources of unwanted noise in the cabin are changing, especially in electric vehicles, where road noise is more noticeable over the silence of the engine. Effective noise, vibration and harshness (NVH) mitigation involves much more than just gap filling.

3M has taken this challenge to heart. Our technicians are studying, mapping and creating new acoustic solutions for today’s and tomorrow’s vehicles. We’re developing materials that help you meet specified decibel levels, and also adjust interior sound quality to help OEMs further differentiate passenger experiences. Explore below.

Sound Solutions

  • preinstalled headliner with 3M™ Engineered Damping Material
    3M™ Engineered Damping Material (EDM)

    Thin, flexible, conformable material delivers high NVH performance from smaller parts, at a much lower weight than traditional constrained layer damping materials. Featuring a low-density engineered stem web standoff layer, it damps structure-borne noise even in designs using lightweight substrates such as composites. Flexible, conformable, adhesive-backed and customizable, it installs more easily, cleanly and in more places vs. butyl or bitumen.

  • 3M thinsulate acoustic insulation used in a door pillar
    3M™ Thinsulate™ Acoustic Insulation

    High-performance acoustic material delivers absorption and heat stability with the potential to reduce weight compared to alternative materials. It features an internal web containing polyester (PET) fibers that add loft, strength and stability and extremely fine polypropylene (PP) fibers that allow for high-energy sound absorption. This material attaches easily using tape, ultrasonic welding, hot melt adhesive or mechanical fasteners.

3M Adhesive Transfer Tapes
3M Double-Sided Tapes
  • 3M™ Scrim reinforced transfer tape 97053 applied on car interior

    Double-sided, acrylic adhesive tapes provide excellent bonds to a wide range of substrates – ideal for bonding dissimilar materials and for combined tape solutions in areas where BSR is a concern. Adhesives bond without curing and deliver excellent temperature and environmental resistance.

3M Reclosable Fasteners
  • 3M™ Dual Lock Reclosable Fastener on sunroof application

    An excellent alternative to metal fasteners, these positive-locking blind fasteners feature mushroom-shaped polyolefin stems that snap together. They can be mixed and matched for a range of closure strengths, and hold their strength even under repeated use – in fact, they can be opened and re-closed up to 1000 times in high cycle applications.

3M Wire Harness Tapes
  • Preinstall of 3M wire harness tapes in headliner

    Double-sided acrylic sealing tapes feature excellent initial adhesion, heat resistance and durability compared to conventional butyl sealing tapes. They bond to rough or highly irregular surfaces and can be used for attachment support of low surface energy materials or bonding of impact relaxation materials, spacers, pads or sponges.
