Soundown Corporation

What Soundown Corporation does

Soundown Corporation is a Salem, Massachusetts-based, family-owned manufacturer of noise and vibration control materials founded in 1984 by MIT-trained engineer Joseph Smullin. The company designs, produces, and consults on acoustic insulation (TuffMass mass-loaded vinyl and UL-listed variants, acoustic foam, hull boards), vibration damping products (MIL-PRF-23563D-qualified damping tiles, EcoDamp constrained-layer dampers, Sylomer elastomer mounts), drive-line solutions (engine and gear mounts, exhaust silencers, and the Evolution Marine Shaft System acquired in 2017), and engineered kits for marine, architectural, industrial, and medical (MRI) applications. Technical depth is anchored in decades of classified US Navy acoustic work and high-end mega-yacht refits and new builds, with products meeting USCG, IMO, UL, and military specifications.

Soundown generates revenue through three channels: enterprise field sales via regional sales managers and field-engineering consultation for custom systems (primarily marine OEMs, defense, and architectural projects); e-commerce direct sales of branded acoustic products and DIY-oriented NRE (Noise Reduction Engine) kits to boat owners and small commercial customers; and complementary product distribution (e.g., Rubber Design, Sylomer). Pricing for standard shop SKUs is publicly listed at $19-$384 per unit, while custom noise control systems for yachts, industrial sites, and architectural projects are quote-based. The company employs roughly 40 people, operates a marine sales office in Fort Lauderdale, Florida, and serves customers across the US, Canada, Europe, the Middle East, Asia Pacific, South America, and Oceania.

Core offering

Soundown Corporation manufactures and supplies noise control materials including acoustic insulation, vibration damping products, exhaust silencers, mount/isolation systems, and oil bath shaft systems for marine (yachts and vessels), architectural, industrial, and medical equipment applications. The company combines a proprietary product catalog with engineering consultation and custom system design, distributing through regional field sales, an e-commerce shop, and trade shows.

Product overview

Soundown Corporation offers a comprehensive noise control product portfolio designed for marine, architectural, industrial, and medical applications. The core product line centers on acoustic insulation solutions (TuffMass, TuffMass-UL, Acoustic Foam, Hull Boards), vibration damping products (Vibration Damping Tiles, Vibration Damping Sheet, EcoDamp), and mount/isolation systems (Sylomer, Engine Mounts, Gear Mounts). The company acquired Evolution Marine (2017), adding oil bath shaft systems (EMSS) to their drive line solutions portfolio. Products are complemented by installation materials (ATA-30 Adhesive, Tape, Pins/Washers, Gaskets) and DIY-oriented NRE (Noise Reduction Engine) Kits for boat owners. Soundown positions itself as a systems and consultation company with products available through their shopping system for both professional installers and end consumers.

One partnership is on record.

• Evolution Marine (The Evolution Company)coreStrategic or Co-development Partner · 29 January 2017Soundown acquired The Evolution Company of Rockland, Maine in 2017. Evolution is best known for their Evolution Shaft Systems, oil bath shaft systems for marine vessels that improve efficiency and reduce shaft whining sounds. Soundown had worked with Evolution for decades before the acquisition. The acquisition enables Soundown to share latest manufacturing techniques and audio engineering knowledge while combining them with Evolution's proven hardware and quality reputation. Evolution continues to produce products including EMSS (Evolution Marine Shaft System), Shaft Razor rope cutter, and Evolution Flexible Shaft Coupling.
