Sonum + and the Sonum box are independent or complementary:
Independent if you want to insulate in a given direction, complementary if you want to insulate your air conditioning unit or heat pump in all directions.

Sonum+ can be easily moved to isolate in a given direction. In summer, for example, between your outdoor dining table and your heat pump, and in winter between the latter and your neighbours’ house.

Our Sonum + sound wall is completely tailor-made. It can be straight, on two sides (angles of your choice), or any other shape to adapt perfectly to your problem.

Our acoustic wall is the result of several years of research and collaboration with a partner acoustic design office.
A dozen colors, imitation wood finishes, artificial foliage, Sonum + will blend perfectly into your exterior. Aesthetic and efficient, Sonum + is acoustic peace!
