Abstract : Nowadays, the sound insulation and the acoustic conditioning are problems to raise in the building constructions and in the design of certain enclosures. Last years the legislative scene in terms of noise and vibrations has been changed supposing, the final approval of the DB-HR of the CTE in Spain, the most important change. Within this new legislative framework, besides to increased sound insulation requirements appear new requirements related to the acoustic conditioning of certain enclosures. So that, gradually, has been created the need for look for new materials with acoustic properties which meet the new acoustics requirements. On the other hand, are well known the economic problems, storage problems and environmental problems that entail the remainders in a production process. Specially, in the textile industry, tones of remainders are generated in the manufacturing processes. Many of these residues are like a powder with difficult recycling, but it can be recycled by means of the wet-laid technology. This work evaluates the feasibility of include, as solutions to the new acoustics requirements, new nonwoven made with textile remainders using the wet-laid technology.

Keywords : wet laid sound absorption coefficient sound insulation
