Floated Bulkheads 



Floated Bulkheads, or even an entire floating interior, can have a significant effect on noise reduction, essentially turning your floor into a layered sound absorber. Floating a bulkhead means adding layers - hard surfaces raised or suspended with small fasteners, creating a thin, absorbent layer of either material or air in addition to the standard bulkhead.

This approach is often used in staterooms, but it can also work in the engine space if there is enough clearance.

Here are some examples with cut-away details showing how floating bulkheads - as either walls or entryways - work.
