How We Approach Noise
We combine sound-path mapping (structure-borne vs. airborne), vibration analysis, and thermal checks to isolate causes. Then we fix—not just damp—what’s wrong. Below are the technician tips we use every day on service calls.
Tip 1: Start with the Mounts—Silence Begins at the Bed
Worn or hardened engine mounts allow vibrations to travel straight into the hull. We:

• Inspect rubber hardness, compression set, and bolt tension.
• Replace with spec-matched or upgraded isolation mounts.
• Realign engine/shaft to manufacturer tolerances.

Result: Major drop in structure-borne noise and fewer cabin buzzes. This is often the single biggest improvement per euro spent.
Tip 2: Build a Smarter Engine Room Envelope
Even a great engine will sound loud if the compartment leaks noise. Our Boka Bay yacht service team:

• Lines bulkheads with high-density barriers plus decoupled foam for mid/high frequencies.
• Seals cable and hose penetrations with fire-safe grommets.
• Adds mass-loaded layers to hatch lids and service panels.

Bonus: Correct insulation keeps heat in check, stabilizing engine-room temps and extending component life.
Tip 3: Tame the Exhaust—Where Roar Becomes a Murmur
Exhaust bark carries across the water and into the saloon. We recommend:

• Waterlock and muffler upgrades sized for your engine’s flow.
• Flexible bellows and anti-siphon checks to cut resonance.
• Leak tests to eliminate hiss and soot smells that often accompany noise.

Result: Noticeably quieter tone and reduced drone at cruising RPM.
Tip 4: Balance the Rotating Gear, Not the Cabin Doors
If doors, lockers, or tableware rattle at certain RPMs, suspect imbalance. During yacht repair Tivat, we:

• Check propeller runout and shaft straightness.
• Dynamic-balance prop/shaft assemblies and verify strut bearings.
• Recommend low-noise prop designs (skewed blades, tuned pitch) when appropriate.

Result: Fewer vibration peaks, smoother throttle feel, better fuel efficiency.
Tip 5: Tune the Engine Like a Pro—Quiet Is a Symptom of Health
Mechanical chatter often traces back to setup and wear. Our technicians:

• Set injection timing and idle quality, recalibrate ECUs if applicable.
• Replace glazed belts, noisy idlers, and tired bearings.
• Verify valve lash and inspect engine ancillaries (alternators, pumps) that can whine under load.

Result: Lower mechanical clatter, faster starts, and cleaner burn—performance you can hear (or rather, not hear).
Tip 6: Control Airflow Noise Without Starving the Engine
Airborne whistle and whoosh usually come from poorly designed intakes or vents. We:

• Add lined intake ducts with smooth radius bends.
• Install acoustic louvers that maintain airflow.
• Separate intake and exhaust air paths to prevent turbulent cross-talk.

Result: Quieter cabins without compromising cooling air volume.
Tip 7: Decouple Everything—Pipes, Cables, and Panels
A perfectly insulated room still resonates if systems are hard-coupled to the hull. Our yacht service Montenegro team:

• Uses isolation clamps on fuel, raw-water, and exhaust lines.
• Adds neoprene or EVA gaskets beneath panels and equipment bases.
• Applies constrained-layer damping on “singing” plates and lockers.

Result: Less secondary noise and fewer mystery buzzes at specific RPM bands.
Tip 8: Measure, Don’t Guess—Prove the Gains
Every project includes baseline and post-work readings:

• dB(A) and dB(C) levels at helm and saloon.
• Vibration (mm/s RMS) at mounts and gearbox.
• Thermal and airflow snapshots to confirm safe operating margins.

This data-first approach ensures each euro spent delivers audible results.

What About Costs?
Budgets vary by yacht size and goals, but here’s how owners typically invest:

• Mounts & realignment: moderate investment with high ROI.
• Engine-room acoustic package: scalable; from quick wins to full rebuilds.
• Exhaust upgrades: mid-range, strong perceptual improvement.
• Prop/shaft balancing: cost-effective, performance-plus.
• Comprehensive tuning & service: essential baseline during any noise project.

Our team will scope a phased plan so you can stage the work across yard periods.
