About us

Founded in 2012, DECIBEL is the fastest growing innovator and manufacturer of soundproofing systems, acoustic materials and industrial noise control solutions; for the residential, public and industrial sectors. 

With our headquarters located in Sofia, Bulgaria, and our production facility located in Botevgrad, Bulgaria, we are currently exporting our products and services to over 36 countries in Europe, Asia and Africa.

Our engineering innovation has always been our core strength. We offer the most effective soundproofing solutions, and we go even further by offering our full services solutions to clients around the globe. 

We take care of everything from diagnosing the problem and all it's parameters through to designing the most effective solution, followed by production, installation and maintenance.

We are innovators, believers and doers.
We are fast, accurate and committed to results that matter.

First Over The Line (Pty) Ltd, trading as DECIBEL AFRICA is the Sole Distributor of  DECIBEL International's Sound Proofing and Acoustic Solutions in the Republic of South Africa and SADC member countries.

DECIBEL Africa is a  Level 1 BEE company with a Procurement Recognition level of 135%.


Our mission is to improve the quality of sleep, rest and work of as many people as possible.


Classical soundproofing and acoustics have limitations. We develop the future of soundproofing and acoustics through science and innovation.


We believe that acoustic consultancy, product development & production, installation and result verification should be all done under one roof.  Why? Because only by closing the cycle, from the drawing board to the end measurements on site, one can be 100% sure that the results achieved are real and can meet the highest expectation of the user. 

And yes, we know this is unconventional, but we never were conventional.
