Ship cabins: airborne sound and panel radiation

A booming cabin may be driven from the engine room, or radiated into the room by panel vibration; damping addresses the latter path only.

Two transmission paths

Compare moored or anchored, equipment-only and sailing conditions, and investigate two paths: airborne sound along door gaps and ventilation routes, and structure-borne vibration through equipment connections and panels.

Damping addresses structure-borne vibration

Damping is used on panels and similar structures. Absorption, insulation and requirements for corrosion, moisture and fire are checked separately against the product data and the project specification.

Panel sample

Choose a representative panel for a sample, record surface preparation, batch, coated position and drying conditions, and check that the coverage matches the vibrating area.

Verify under the same condition

Compare before and after with the same equipment status, load and measurement points, measuring panel vibration at the same time where needed; measured values govern.

Tell us whether the cabin issue occurs at berth or under way, and send the noise position and panel details.
