Our partners & customers
Why HSA3 ?
While we focus on applying groundbreaking technologies, we seek partnerships with companies that want to drive innovation together with us. The benefits of our technology are far-reaching:
Cost efficiency
Save on materials, energy, and labor. HSA3 is not only more affordable to purchase than other microperforated absorbers; our technical solution also sustainably reduces your material, energy, and labor costs thanks to its low weight and ease of handling.
True innovation
Go beyond the ordinary. Our solutions encompass not only the application of HSA3, but also the complete research and integration of technological levers into your product. We offer you a technological advantage that goes far beyond standard solutions.
Reliable partner
Environmental awareness as a core value. We place particular emphasis on the sustainability of our products and their manufacturing. HSA3 is made of 100% metal, is fully recyclable, and its efficiency reduces the ecological footprint throughout the entire life cycle of your product.
Broadband absorption
Effective sound absorption across the entire frequency spectrum of 250 Hz to 5000 Hz - even at low frequencies.

User reviews
This is what our partner via HSA3
Read how our patented meta-material is already being used successfully in practice.
HSA3 completely won us over immediately! At very manageable costs, we were able to more than halve the noise from our machines – and all with an extremely hygienic solution. Furthermore, ABSORA provided us with truly valuable advice that went far beyond what other acoustic consultants offer.
Our collaboration with ABSORA has been extremely successful. They consistently impress us with their ability to find unconventional solutions to technical challenges in a very short time. Furthermore, their hands-on approach and cost-consciousness help us to quickly achieve market-ready results.
