Acoustical Products Made in USA.
Lightweight vessel noise retrofit focuses on reducing high noise levels in existing ships without adding excessive weight, using flexible mass-loaded barrier systems designed for structural limitations.
Across New Jersey shipyards and coastal vessels, many older or lightweight builds operate with noise levels between 85–105 dB(A) in engine rooms and mechanical spaces. The challenge is that these vessels cannot support heavy acoustic systems without affecting performance or stability.
Under OSHA standards applied in New Jersey:
- 85 dB(A) – Action level
- 90 dB(A) – Permissible exposure limit
👉 The goal is to reduce noise without increasing structural load.
What Is the Best Way to Reduce Noise on an Existing Vessel?
The most effective method is using lightweight, high-density barrier systems that block sound while remaining flexible enough for retrofit installation.
Why Traditional Soundproofing Doesn’t Work
Many systems rely on heavy materials that are not suitable for retrofit conditions:
- Adds excess weight to the vessel
- Difficult to install in tight or irregular spaces
- Not compatible with older vessel structures
This makes them impractical for many New Jersey marine retrofit projects.
Best Retrofit Solution for Marine Vessels
MassiCore® Marine 90 (ANC-MB90) provides an ideal balance of performance and weight.
Key advantages:
- Mass-loaded vinyl barrier blocks airborne noise
- Flexible for walls, ceilings, and partitions
- Installs easily in existing vessel layouts
This makes it highly effective for marine noise retrofit in New Jersey shipyards and vessels.
How Much Noise Reduction Can You Expect?
With proper installation:
- Noise reduced from 95–100 dB(A)
- Down to approximately 65–70 dB(A)
This significantly improves both compliance and onboard conditions.
Can You Soundproof a Vessel Without Adding Weight?
Yes. Modern barrier systems are designed to deliver high sound blocking performance with minimal added weight, making them ideal for retrofit applications.
Why This Matters in New Jersey Marine Operations
From Newark ports to coastal fleets, many vessels require upgrades without structural changes. Without lightweight solutions, operators are limited in how much noise control they can achieve.
Unresolved noise leads to:
- Ongoing exposure in high-noise areas
- Reduced crew comfort and performance
- Inefficient retrofit results
