Step into a pump room on a vessel or industrial site, and the first thing you notice isn’t the equipment—it’s the noise. A constant, aggressive hum pushing 85–100 dB(A), bouncing off steel walls, vibrating through floors, and traveling far beyond where it should.
This isn’t just loud—it’s uncontrolled.
In California, that level of noise quickly becomes a compliance issue. Under Cal/OSHA regulations, anything above 85 dB(A) requires action, and sustained exposure at 90 dB(A) crosses into unsafe territory. Most pump rooms? They exceed both—daily.
Why This Noise Doesn’t Stay Contained
Pump noise is persistent because it doesn’t travel in just one way—it finds every path available:
- It moves as airborne sound, filling surrounding spaces
- It transfers as structure-borne vibration, traveling through steel and piping
- It bypasses basic insulation, spreading into adjacent compartments
That’s why traditional fixes often fail. The noise isn’t just escaping—it’s propagating.
The Shift: Controlling Noise at the Source
Instead of chasing noise after it spreads, the real solution is stopping it where it starts.
MassiCore® Marine 90 (ANC-MB90) is designed exactly for that.
It’s not a rigid panel or bulky system—it’s a flexible, high-mass sound barrier that conforms to real-world pump room conditions. Around pipes, across uneven surfaces, inside tight mechanical layouts—it installs where other systems can’t.
What makes it effective:
- Heavy-duty sound barrier vinyl blocks airborne noise directly at the source
- Flexible sheet design adapts to complex equipment layouts
- Ideal for walls, partial enclosures, and retrofit applications
What Happens After Installation
Once properly installed, the difference is immediate and measurable:
- Noise levels drop from 95–100 dB(A)
- Down to approximately 65–70 dB(A)
That’s the difference between a hazardous environment and a controlled one.
The impact:
- Meets Cal/OSHA noise requirements
- Reduces worker fatigue and exposure risk
- Improves communication and overall safety
Why This Matters in California
In high-traffic ports like Los Angeles, Long Beach, and Oakland, noise control isn’t optional—it’s enforced. Facilities that ignore pump noise don’t just deal with discomfort—they face:
- Regulatory violations
- Operational inefficiencies
- Long-term workforce health risks
