Soundown is a sound and vibration dampening material that can help to reduce engine noise in your cockpit. The combination of high density rubber core, and lower density foam material help to dampen a combination of low frequency and high frequency noise and vibration.
When using Soundown, we recommend cutting and adhering appropriately sized sheets to bulkheads, decks, and hull plating in areas of higher vibration potential, such as over propellers, in the region of thrusters, and in the vicinity of the engine compartment.
Package Contains:
QTY 1 - 32 inch x 54 inch sheet
Please Note:
Sheets are not self-adhesive.
How It Works:
Soundown is an easily applied damping layer for stopping reverberant “ringing” vibration in heavy plate constructions. Structural damping material absorbs acoustic energy and transforms it into heat before it can build up and radiate as sound. Substrates upon which the sheets are commonly installed include steel, aluminum, and fiberglass laminate. This compared to heavy traditional bitumen-based sound dampening materials which work by increasing panel mass to alter resonant frequency.
