DECIBEL

What DECIBEL does

DECIBEL PLC, headquartered in Sofia, Bulgaria, is a vertically integrated designer, manufacturer, and installer of soundproofing and acoustic treatment solutions for industrial, commercial, residential, and specialty environments. The company operates its own production facility in Botevgrad, Bulgaria, and supports ten or more country markets (Bulgaria, UK, Germany, Austria, Romania, Serbia, Poland, Finland, Russia, USA, South Africa) through regional offices and country-specific websites, with a wholly-owned UK subsidiary (DECIBEL INTERNATIONAL UK LTD) anchoring its Western European presence. Its product portfolio spans wall, ceiling, and floor soundproofing systems (the patented MUTE SYSTEM family built on DClox™ anti-vibration mounts, Block System, DCvisco viscoelastic membranes), architectural acoustic panels (PET felt, perforated wood, fabric-wrapped, wood wool, foam), industrial noise control (enclosures, louvres, silencers, anti-vibration mounts, audiology booths), and measurement devices (sound level meters, dosemeters, safety kits).

The firm's competitive technology is built on mass-spring-mass acoustic principles combined with patented anti-vibration mount geometry that limits wall contact to under 1%, supporting documented performance metrics of 15-24 dB noise reduction (Block System) and delta Lw of 35-37 dB for floor impact membranes. Revenue is generated through three primary streams: (1) one-time product sales of soundproofing materials and acoustic panels, (2) one-time sales of industrial noise control products and measurement devices, and (3) professional services for acoustic consulting, simulation, engineering, measurement, supervision, and full project execution. Pricing is project-based and not publicly disclosed. The go-to-market combines enterprise field sales for large industrial and commercial customers, country-specific websites and inside-sales for mid-market buyers, and an e-commerce storefront (decibel.shop) for SMB and residential customers, supported by a 5,000+ project reference base across 42+ countries and a customer roster that includes Hilton, SAP, Siemens, Intel, Equinix, Nissan, ABB, and the European Parliament.

Direct peers

• Acoustical Solutions: US-based distributor and manufacturer of acoustic panels, soundproofing materials, and noise control products with a strong e-commerce presence via AcousticalSurfaces.com. Competes with DECIBEL in architectural acoustic panels, foam, and soundproofing across B2B and B2C channels.
• Industrial Noise Control (INC): Specialist in industrial acoustic enclosures, noise barriers, and silencers, primarily serving North American manufacturing and power generation. Closely matches DECIBEL's industrial noise control product line, including custom enclosures and HVAC silencing.
• Kinetics Noise Control: US-based manufacturer of acoustic and vibration isolation products including hangers, mounts, wall/ceiling panels, and industrial noise control enclosures. Directly comparable product range to DECIBEL's noise control category and serves similar industrial and architectural customers.

Regional players

• Soundproof Cow: US-focused e-commerce retailer of consumer and prosumer soundproofing materials (mass loaded vinyl, acoustic foam, isolation products). Comparable in product range to DECIBEL's residential/e-commerce line but operates only in the US market.

Broad incumbents

• Rockwool: Global stone wool insulation manufacturer whose products serve acoustic, fire, and thermal applications in residential and commercial construction. Rockwool competes with DECIBEL in wall and ceiling insulation and has the scale, R&D, and distribution reach that DECIBEL lacks.
• Knauf Insulation: One of the world's largest insulation manufacturers with mineral wool and other acoustic/thermal products. Knauf serves the same wall, ceiling, and floor soundproofing applications as DECIBEL, particularly in European residential and commercial construction, and is far larger.
• Saint-Gobain Ecophon: Saint-Gobain's acoustic ceilings and wall panels division is a direct competitor in office, education, and healthcare acoustic treatment. Both firms offer sound-absorbing panel systems and project design services for commercial interiors, but Ecophon operates as part of a much larger building materials conglomerate with broader distribution.
• Armstrong Ceiling Solutions: Major manufacturer of acoustic ceiling and wall systems for commercial buildings, including offices, healthcare, and education. Overlaps with DECIBEL's acoustic panel offering for interior fit-out, but operates as a broad building products player with US-centric distribution.

Emerging players

• Cellofoam North America: Manufacturer of soundproofing and insulation products including floor underlayments and wall systems. Provides comparable closed-cell polyethylene and rubber underlay products (akin to DECIBEL's Dpact, SYLPRO, and SYLWOOD) for residential and commercial soundproofing.
• BAUX Acoustic Panels: Swedish design-led manufacturer of PET felt and wood-wool acoustic panels for offices, schools, and modern interiors. Overlaps with DECIBEL's BEELIVE PET felt and wood wool panel lines but focuses on premium architectural design rather than full-service acoustic engineering.
