Using Knitted Mesh for Noise Suppression and Vibration Reduction
·5 min read
Knitted wire mesh absorbs sound energy and damps vibration in engines, exhausts, HVAC, and industrial machinery.
Noise and vibration shorten equipment life, breach workplace limits, and reduce comfort. Knitted wire mesh provides a durable, fire-safe, and reusable solution where foam or fibreglass cannot survive.
How knitted mesh absorbs sound
Sound waves entering the mesh structure are converted to heat through friction between air and the fine interlooped wires. The porous, three-dimensional network dissipates energy across a wide frequency range.
How knitted mesh damps vibration
When compressed into pads or rings, knitted mesh behaves like a metal spring with internal friction. The wires slide microscopically against each other, converting kinetic energy into heat.
Typical applications
- Automotive exhaust mufflers and decouplers.
- Industrial silencers for blowers and compressors.
- HVAC duct silencers.
- Vibration isolators under pumps, motors, and generators.
- Aerospace engine mounts and isolators.
Advantages over foam and rubber
- Operates from cryogenic to 600 °C+ depending on alloy.
- Resistant to oils, fuels, and chemicals.
- Non-flammable and does not outgas.
- Linear performance over thousands of cycles.
