SNA is an acoustic consultancy specialised in the most technically demanding projects. We diagnose the real problem, design the solution and execute with full technical responsibility.
Over 25 years pushing the limits of conventional acoustics.
Three pillars shape our approach to every project: applied innovation, rigorous diagnosis and the technical capability to solve what others cannot.
Applied innovation
We integrate advanced diagnostic tools, computational modelling and proprietary technical solutions. Basslock®, our latest patented solution, was born from a question the market could not answer.
Three areas of technical specialisation.
Industrial acoustics →
High-power machinery, production environments, occupational noise exposure, structural vibrations. Technical interventions from diagnosis to construction solutions.
Architectural acoustics →
Residential buildings, hotels, offices, educational centres, technical rooms. Insulation, absorption and acoustic control integrated from design or in existing buildings.
Environmental acoustics →
Acoustic impact assessment, noise maps, screens and barriers, infrastructure protection. Diagnosis and noise solutions in urban and industrial environments.
Acoustic engineering with independent judgement.
SNA was founded with the conviction that acoustic engineering can — and must — go beyond mere regulatory compliance. Over more than twenty-five years we have developed our own methodology, based on in-depth diagnosis, bespoke design and manufacturing and execution with full technical responsibility.
We are certified as an Innovative SME, with a patented product — Basslock® — developed in response to a specific technical problem that the market could not solve: effective low-frequency sound insulation with airflow.
Our team combines training in acoustic, mechanical and civil engineering with accumulated experience in industrial, building and environmental projects. We do not apply catalogue solutions. We design the answer to each project's specific problem.
Over twenty-five years of specialised technical work.
The technical foundation that makes the difference
SNA was born from real field knowledge. Over a decade of experience in industrial acoustics, the import of the first acoustic camera in Spain and a progressive specialisation in the most demanding sectors — energy, data centres, critical infrastructure — built a technical foundation that is our greatest differentiator today.
From applied research to an unprecedented metamaterial
When conventional solutions were no longer enough, we created our own. Years of in-house R&D resulted in Basslock®, an engineered metamaterial that changes the rules of acoustic insulation. A technology protected by national and international patents, already applied in sectors from the energy industry to major events.
From Spanish engineering to global technology
SNA has evolved from a specialised engineering firm to a technology company with an industrial structure. A corporate holding, a licensing model designed for replicability and a European expansion strategy underway. The field knowledge that started it all is preparing to scale without borders.
Projects in technically demanding environments.
We have worked with organisations facing acoustic challenges in critical infrastructure, institutional buildings and top-tier industry.
