<h3>About Soundown: Engineering Quiet Since 1983</h3><p>Not every sound is welcome. The deep thrum of an engine reverberating through a hull, the tooth-rattling hum of machinery shaking through a compartment floor — these are the kinds of noise problems that <strong>Soundown</strong> was built to solve. Founded in 1983, Soundown is a company that specializes in noise control and vibration abatement, born with the mission of solving every possible noise problem on boats — and the scientific approach and deep knowledge of sound principles have made Soundown a leading company on the market of noise reduction systems.</p><p>Soundown Corporation manufactures and distributes noise and vibration control materials for marine and many other industries. Headquartered in Salem, Massachusetts, the brand has grown from its marine roots into a globally recognized engineering authority, with applications spanning industrial, architectural, and medical environments. Working on these solutions for years, that experience and expertise is what has made Soundown the worldwide leader in noise control.</p><h3>How Soundown Approaches Noise Control</h3><p>What sets Soundown apart is its systems-level thinking. Rather than simply selling a product, Soundown engineers layered solutions that address both airborne noise and structure-borne vibration simultaneously. Soundown Barrier Composite Materials use an array of base materials to achieve specific results and are among the best materials for lining engines, generators, and other noisy spaces — absorbing reflecting noise within machinery spaces while creating an effective barrier against sound transmission through walls, panels, and bulkheads.</p><p>At the heart of many of their solutions is the Barrier Composite family. Soundown Barrier Composite Insulation is the most commonly used material due to its wide range of applications and excellent acoustic properties — typically a fire retardant polyether foam absorber and decoupler type with a mass-loaded PVC barrier in one of several different weights, finished with a rip-stop Mylar vapor barrier. Barrier composite materials are available in 1/2 to 4-inch thicknesses, depending upon the material configuration.</p><p>Beyond flat insulation panels, Soundown's full lineup includes engine mounts, equipment mounts, exhaust silencers, marine mufflers, acoustic barriers, and mass damping layers — making it one of the few brands capable of addressing noise at the source, in the transmission path, and at the receiving surface all at once.</p><h3>Sound Insulation for Marine &amp; Engine Applications</h3><p>Soundown's flagship product area is <a href="/7581-soundown-sound-insulation-200976">sound insulation</a>, where their composites have earned a reputation for excellence in some of the most demanding environments imaginable. Acoustic insulation is crucial to reducing unwanted noise traveling through spaces, walls, seams, and gaps. Soundown's TuffMass mass-loaded vinyl and their vinyl/foam composite panels are engineered specifically for these challenges. TuffMass is a specially developed, mass-loaded vinyl (MLV) product offering superior acoustic transmission loss combined with good damping properties — available in surface densities of 1/2, 1, 1.5, and 2 lbs/ft&sup2;, suitable for use in all types of construction and offering STC ratings up to 32.</p><h3>Hood &amp; Engine Compartment Insulation</h3><p>Soundown's barrier composite panels are equally well-suited as hood insulation pads for automotive and marine engine compartments. Soundown insulation barriers are an effective treatment for airborne noise that radiates from engines and other machinery — the standard composite consisting of a layer of mass-loaded vinyl sandwiched between two layers of polyether fire retardant foam, covered by a thin vapor barrier facing, designed specifically for the attenuation of sounds from engines, generators, pumps, and other equipment with significant bass and mid-range frequency components.</p><h3>Why Engineers and Boaters Trust Soundown</h3><p>Soundown provides materials with IMO fire ratings that are required in larger yachts, offshore commercial vessels, and passenger vessels — a testament to the brand's commitment to safety as well as acoustics. Whether you are outfitting a performance boat, deadening a vehicle engine bay, or building a quieter industrial enclosure, Soundown brings decades of noise engineering expertise to every panel, mount, and barrier they produce.</p>
