Research focuses on the use of alternative raw materials and on finding new solutions to reduce noise in the context of issues related to environment, is of great interest and great actuality. Composite materials with fir sawdust, used rubber granules and textile waste; Aracet (polyvinyl acetate) and hydrated lime as a binding material, were used in this research. Materials acoustic absorption coefficient was found using the impedance tube method. The values obtained show that these materials can be used for absorbing sound waves in the 400 ? 2400 Hz frequency range. From the analysis of the experimental results, it can be observed that for the materials obtained in this research, the acoustic absorption coefficient value increased with the increase of the fir woods percentage used. The materials obtained using polyvinyl acetate as binder have better sound absorption properties than those obtained with lime-hydrated lime as binder. The presence of rubber granules in the material composition leads to an improvement in the sound absorbing properties in the 800-1600 Hz frequency range. The material obtained from 25% textiles, 75% fir wood, and Polyvinyl acetate as binder has the best acoustic absorption coefficient, of 0.97 at the frequency of 1500 Hz.
