  5. 34. What's Next in Sustainable Acoustic Materials?

    University essay from Lunds universitet/Innovation

    Author : Klas Hellqvist; Anna Andersson; [2020]
    Keywords : Sustainability; Acoustics; Materials; Sound Absorption; Technology and Engineering;

    Abstract : As industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. READ MORE
