Acoustical Products Made in USA.
Noise isn’t always steady—and that’s where the real problem begins.
In many industrial and marine environments, operators aren’t dealing with just one type of noise. Instead, they face a combination of continuous background sound and sudden, high-energy impact noise. Together, these create an unpredictable acoustic environment that’s harder to control and even harder to work in.
Across Texas industrial plants and offshore marine operations, equipment like presses, valves, compressors, and hydraulic systems generate fluctuating noise levels between 85–105 dB(A). The constant hum blends with sharp bursts of impact energy—making the space feel louder than it actually measures.
And that’s where standard solutions fall short.
Under Occupational Safety and Health Administration standards followed in Texas:
- 85 dB(A) – Action level (hearing conservation required)
- 90 dB(A) – Permissible exposure limit (PEL)
When both continuous and impact noise are present, controlling just one isn’t enough—both must be addressed together.
Why Mixed Noise Is Harder to Control
Continuous noise and impact noise behave differently—and require different strategies.
- Continuous noise (fans, motors, airflow) travels through the air and requires mass blocking
- Impact noise (pistons, valves, mechanical strikes) creates sudden spikes that require absorption and damping
Most systems only target one type.
That’s why operators often notice:
- Inconsistent noise levels throughout the day
- Sudden spikes that feel louder than average readings
- Ongoing discomfort despite installed acoustic treatments
Because the system isn’t solving the full problem.
How Do You Control Both Continuous and Impact Noise?
The key is using a composite acoustic system that combines blocking and absorption in one solution.
To effectively manage both noise types, the system must:
- Use a high-mass barrier layer to stop airborne continuous noise
- Include an absorptive layer to control impact energy and reflections
- Provide full coverage across walls, equipment, or enclosures
- Adapt to changing conditions in dynamic industrial environments
Single-layer solutions fail because they only address one side of the equation.
A Smarter Solution: Dual-Control Acoustic System
AcuvaCoreâ„¢ 32 Marine Acoustic Barrier Composite (ANC-ACV-32-B45) is designed to handle both continuous and impact noise simultaneously.
It works by combining:
- A high-density vinyl barrier to block steady airborne noise
- An integrated absorptive backing to manage impact spikes and reflections
Why it performs in real-world environments:
- Handles fluctuating noise conditions without performance drop
- Flexible installation for walls, machinery, and enclosure systems
- Effective for both industrial facilities and offshore applications
- Maintains consistent acoustic control throughout operation cycles
Instead of reacting to noise, it controls it at the source.
What Happens When Both Noise Types Are Controlled
When continuous and impact noise are treated together, the environment stabilizes.
- Noise levels reduced from 95–105 dB(A)
- Down to approximately 60–70 dB(A)
But the biggest change isn’t just the numbers—it’s the consistency.
Operational improvements:
- More stable and predictable sound environment
- Reduced fatigue from sudden noise spikes
- Improved focus and communication
- Better compliance with OSHA standards in Texas operations
Why This Matters in Texas Industrial & Marine Environments
In Texas manufacturing plants, refineries, and offshore platforms, operations run continuously under demanding conditions where noise is constant—and often unpredictable.
When mixed noise is not properly controlled:
- Workers experience higher perceived noise levels
- OSHA compliance becomes harder to maintain
- Productivity and safety are affected
- Traditional acoustic solutions underperform
Controlling both continuous and impact noise isn’t optional—it’s essential for a stable, safe, and efficient operation. AcuvaCore™ 32 provides a proven, high-performance solution for controlling both continuous and impact noise—ensuring consistent, reliable acoustic performance in demanding industrial and marine environments.
