What is Die-Cut Acoustic Insulation?
Die-cut acoustic insulation refers to the process of converting engineered flexible materials, including open-cell foams, fibrous felts, film-faced composites, and high-mass damping materials, into usable custom components that control unwanted noise, vibration, and harshness at the source or enclosure level.
Die-cut acoustic insulation addresses noise and vibration in two main ways:
- Air-borne noise control - Absorbs and attenuates noise that travels through the air (fan noise, airflow turbulence, audible mechanical noise)
- Structure-borne noise control – Dampens vibrations and reduces structural resonances to mitigate vibration energy turning into audible sound (vibrations, squeaks, engine hum, impacts)
Unlike traditional bulk insulation, custom die-cut acoustic components are designed to be integrated into specific geometries, noise paths, and assembly constraints.
The Role of a Converter The bridge between "raw material", and "assembly-ready component"
A converting partner plays the integral role of transforming these raw acoustic materials into assembly-friendly components that can be efficiently integrated into specific assemblies. From managing cabin noise in electric vehicles to masking the low-frequency hum of various appliances, a skilled converter is needed to make these engineered materials usable in the real world.

Managing Noise vs. Vibration: What's the Difference?
As we've established above, noise and vibration are two sides of the same coin - the difference is that unwanted noise travels through the air, and vibration across surfaces and physical objects. Both can be addressed with die-cut acoustic insulation components.
Although they're similar, the materials and strategies used to solve each may vary:
Managing Noise
Managing noise can typically be done in one of two ways:
- Sound blocking -
Sound blocking physically stops the sound from passing through a component, reflecting the acoustic energy back towards the source. Sound blocking requires high-mass materials like high-density polyurethanes and silicone solids.
EX: Rogers BISCO® HT-200 & HT 6000 Series
- Sound Absorption -
Sound absorption essentially acts as a sound sponge, trapping the acoustic energy within the material and converting it into minor thermal energy. Sound absorption typically requires porous, low-density materials to create a challenging path for the sound wave to travel through.
EX: Rogers PORON® 92-09 & BISCO MF1
Managing Vibration
Unwanted vibration can be mitigated using two distinct strategies:
-
Vibration isolation -
Isolation localizes unwanted vibration, preventing it from traveling from one place to another. Soft, high-deflection elastomeric foams are typically used to isolate vibration.EX: Rogers PORON®
-
Vibration damping -
This helps dissipate energy caused by unwanted vibration by turning into small amounts of thermal energy. Vibration-damping materials are viscoelastic, meaning they bend and stretch with the surface they're adhered to which helps convert the kinetic energy into faint heat.EX: Rogers BISCO®

Ask and Engineer: Acoustic Insulation Q&A
Reducing noise at the source level focuses more on mechanical vibration damping. Die-cut gaskets, seals, dampers, and spacers convert direct vibrational energy into low-grade heat to help mitigate the noise.
Addressing noise at the enclosure level focuses more on die-cut components that absorb air-borne noise by preventing noise from escaping cavity.
Yes, JBC leverages our vertically integrated multi-layer laminating capabilities to combine acoustic insulation and vibration-damping materials with thermal reflectors, like aluminum foil, to help mitigate the thermal energy generated by vibration-damping.

Air-borne and structure-borne noise are two distinct challenges that require unique die-cut solutions to properly address.
Air-borne noise: This is sound that travels directly from a source through the air. It can be mitigated using die-cut components that absorb or trap the sound and prevent it from escaping an enclosure.
Structure-borne noise: This type of noise is generated by vibrations that travel through solid materials, requiring die-cut components that directly break or dampen the vibration path.
