Printing the Silence

R&D in Acoustic materials and solutions

Our expertise is based on many years of research in acoustics, focusing on 3D-printed materials for aircraft engine noise reduction.

Our R&D know-how is based on three pillars: additive manufacturing, acoustic materials and metamaterials, and simulation. Used in synergy, they enable us to rapidly develop high-performance acoustic solutions.

Research and development in acoustic materials and solutions

Additive manufacturing, or 3D printing, is a flexible manufacturing process that enables the development of innovative solutions, rapid prototyping, efficient mass production of complex parts, and the creation of components combining exploitable acoustic and mechanical properties.

The combination of conventional acoustic materials with state-of-the-art materials and metamaterials with customized acoustic and mechanical properties, offering high performance.

Analytical and numerical modeling of materials, solutions and their operating environment, also known as digital tween, enabling precise optimization of the products developed.

Helping companies solve their product noise problems

While noise is a major detriment to quality of life, silence is an undeniable added value for products.

That's why we put our expertise at the service of companies whose products face noise problems. We offer advice, support and subcontracting to assess, develop or integrate conventional and innovative acoustic technologies into your products.

Our services are provided in France, in complete confidentiality.

We support your teams from the diagnosis of your products' noise problems to the implementation of solutions.

The solution may be the modification of one of your components, the addition of a supplier's acoustic component, or the development of a customized solution.

We help your teams to develop their skills in the knowledge and understanding of physical acoustic concepts, analytical and numerical simulation, and prototyping best practices.

We produce your acoustic parts using additive manufacturing, and advise on their design and modeling according to the chosen production method.

Adjustable acoustic products for specific needs

To improve the quality of life of as many people as possible on a daily basis, Sil&Add has developed a range of high-performance, affordable acoustic products.

As each situation is unique, our acoustic products are adjustable.

For example, an adjustable acoustic product allows you to choose between optimum protection against road noise or airport noise.
