The noba digi mini system offers an inventive solution to soundproofing and noise control in public spaces. This noise barrier is sustainable and a good exam-ple of circular design as it uses recycled rubber from old tyres. Just four car tyres are needed to make 1 sqm of the sound absorbing panels. The unique decor is inspired by the aesthetics of digital graphics and allows for almost limitless versatility. By using the colour highlights, it is possible to create any structure desired, from stylised figures to completely abstract patterns.
