Design Engineering Dei Boom Mat Sound Dampening Sheet

The Design Engineering DEI Boom Mat sound dampening sheet (also called sound deadening material or vibration damping mat) is made to cut low-frequency noise from structure-borne vibration in automotive applications. It absorbs vibration energy in metal panels. That helps reduce road noise, engine drone, and panel rattles, and gives a quieter, more comfortable interior.

Key Features:

• Multi-layer construction: a viscoelastic polymer damping layer bonded to a durable aluminum wear surface
• Self-adhesive backing for straightforward peel-and-stick installation
• Needs only about 25-50% panel coverage to work well, which saves weight, material, and installation time
• Flexible enough to trim and shape around contours, curves, and tight areas
• Helps improve in-vehicle audio clarity by reducing panel resonance

Boom Mat suits doors, floors, trunks, and other metal panels. Both enthusiasts and professional installers use it. For clean cuts, Design Engineering suggests its Boom Mat blade lock knife, which is sold separately.
