Who we are

DECIBEL - soundproofing and acoustics

DECIBEL is a Bulgarian engineering and production company, founded in 2012 in Sofia. Today, DECIBEL is one of the largest manufacturers of sound insulation and acoustic solutions available in over 38 countries around the world.

Innovation and scientific are leading in our work. In addition to manufacturing and developing noise control systems, we design and install our solutions for customers around the world. Our solutions include soundproofing systems for homes, offices, and clubs; acoustic materials for studios, bedrooms, and hotels; soundproofing industrial cabins for machines and production lines, as well as vibration-isolating solutions for specific production equipment and vehicles.

Our customers and partners around the world choose us because of our short lead times, the sophisticated approach to engineering solutions (which save money), and the guarantee for achieving results that we give.

We pay special attention to the entire cycle of a project - from design, through production, delivery, and installation to its completion with final control measurements.

Over the years, our team has completed over 2700 sound insulation and acoustic projects for residential buildings, clubs, industrial chillers, offices, conference rooms, and even animal shelters and yachts and received references for excellent results from both private clients and architects, investors, project management organizations, construction companies, private and public organizations from Bulgaria, Europe, and Asia.

 

 

Production Facility 

DECIBEL has its own 2000 m2 production facility located in Botevgrad, Bulgaria, which makes us one of the largest manufacturers of sound insulation and acoustic materials in Europe.

For the first time, the DECIBEL factory opened its doors in 2014 and started the production of acoustic diffusers and coatings with electrified fibers - flock. In 2015, the company purchased fast- wire cutting machine for its acoustic blocks formation. Followed by the purchase of machines for metal processing and CNC cutters for the production of perforated and engraved acoustic panels.

To date, part of the production of DECIBEL is robotized, while the fine details are done by our skilled artisans with precise hands. The factory is divided into sectors for processing wood, metal, textiles, and the production of gypsum-composite products.

Daily from our factory are shipped acoustic and soundproofing products to 3 continents, which are distributed to over 20 representatives around the world who offer them in their stores and warehouses.
