Damping of the hull
How do you prevent noise pollution on board your boat or yacht? Vibrations in the hull and sounds from the engine, propeller or bow thruster can significantly disrupt your enjoyment of sailing. De-noising offers a clever solution. This technique helps to reduce annoying sounds and makes your vessel much more pleasant. Read here how de-noising works and what you can do to make your boat quieter?
What is damping?
Damping is a technique that reduces noise pollution by limiting vibrations in plate materials such as aluminium, steel, and plastic. These materials can produce annoying sounds upon contact, such as the sound of a gong. By adding special material to make them heavier, the vibration is reduced and noise disturbance is prevented.
How does anti-vibration work?
Damping works by adding mass to the material. This is done with damping materials that absorb vibrations and limit the movement of the material. The result is reduced sound transmission and decreased noise nuisance.
Vibrations in the hull
On boats and yachts, vibrations often become a source of noise nuisance. These are caused by engines, propellers, or bow thrusters and spread through the hull to the rest of the vessel.
Vibration dampers under the engine
First of all, it is important that the engine is mounted on good vibration dampers. This helps to minimise noise and vibrations. Make sure these dampers are replaced in a timely manner for optimal performance.
Damping of the hull
Further vibrations can be prevented by soundproofing the hull around the engine (and often also above the propeller). For a steel boat, we recommend soundproofing the hull around the engine, propeller and/or bow thruster with EASYdemp Marine self-adhesive soundproofing tile or the EASYdemp self-adhesive soundproofing plate.
This dampens vibrations at the source and prevents these vibrations from travelling through the framework.
Sound of the screw or bow thruster
The screw or bow thruster can cause noise due to moving parts and cavitation. By applying de-dampening to the hull near the screw, resonances are dampened and annoying sound transmission through the water is prevented.
The propeller or bow thruster of the boat causes noise disturbance due to the moving parts, such as the shaft. Additionally, propeller cavitation can be transmitted through the water to the hull of the boat, causing the hull of the ship to vibrate.
Noise pollution from cavitation can be mitigated by equipping the hull near the propeller with damping tiles or plates. This dampens resonances in the hull instead of propagating them.
