Economic development contributes to the exploitation of natural resources with an increase in waste generation, leading to environmental degradation, with the construction sector being one of the main responsible for this action. The correct disposal of waste is complex, whether by management or by its destination, making its use as a raw material for the development of modified materials an advantageous strategy for environmental preservation. Within this context, this research aimed to develop a material from the incorporation of polyester fibers, coming from the textile industry, in a recycled polypropylene matrix. From the optimal incorporation determined by Albuquerque et al., (2021), as being 16.5% for this material, acoustic tests were carried out, through an impedance tube test based on the NBR ISO 10534-2 (1998) standard and in the ASTM-E1050 (2006) standard, for the determination of the material's sound absorption parameters and verification of the statistically collected data. The results of the acoustic tests showed that the manufactured material has a good absorption coefficient in the specific frequency range, determined at 6.3 kHz, making it a suitable material for acoustic application.
