General Information:

Silent Line offers various products for sound deadening. Pending on the type of structure we recommend:

• Steel structures : Sandwich sound deadening
• Aluminium structures : Single sound deadening
• Composite structures : Single sound deadening

Sandwich Sound Deadening (SLP-COMP)

For steel structures we strongly recommend using sandwich sound deadening products such as:
• SLP-COMP 608D or
• SLP-COMP PU30


Loss factor as shown above is the most important parameter related to (sandwich) sound deadening. Sandwich sound deadening meaning steel structure | sound deadening | counter plate (constrained layer) is required in order to reduce radiation (structure- borne noise becoming air-borne noise) from the structure as well as increase the transmission loss of the structure.

Most common areas to apply sandwich sound deadening:

- Hull plating above the propulsion propellers
- Gearbox foundation
- Hull structure forward of the engine room (Guest | VIP)
- Forward engine room bulkhead application inside the accommodation (Guest | VIP)
- Bow thruster area
- Engine room casing application inside Salon | Dining
- Deck structure above the engine room
- Raised hull structure until lower side window
- Super structure in Salon | Dining until lower side window

Single Sound Deadening (SLP-COMP)

For aluminium structures we recommend SLP-DAMP 3100 | 3101
or
the below shown SLP-CLD plates which are adhesive and easy to install.

Most common areas to apply sandwich sound deadening:

- Hull plating above the propulsion propellers
- Gearbox foundation
- Hull structure forward of the engine room (Guest | VIP)
- Forward engine room bulkhead application inside the accommodation (Guest | VIP)
- Bow thruster area
- Engine room casing application inside Salon | Dining
- Deck structure above the engine room
- Raised hull structure until lower side window
- Super structure in Salon | Dining until lower side window


For composite and wooden structures, we recommend SLP-MASS X sheets available in 3.5 and 6 mm to be glued against the structure.
The density of the SLP-MASS sheets is 2300 kg/m3.
