Diseño y construcción de un panel fonoabsorbente sostenible para la reducción de ruido, utilizando PVC y caucho reciclado

Abstract

The purpose of this research was to design and build a prototype of a sustainable sound-absorbing panel to mitigate noise, using Sintra-type PVC and recycled tire rubber, focused on optimizing low and mid frequencies. To evaluate its performance, mechanical and acoustic tests were carried out, reconstructing an impedance tube, acoustic box, and soundproof room. In addition, the frequencies were evaluated using REW software to generate pink noise, and the sound pressure was measured with a sound level meter and calibrated microphones; statistical analysis was performed with SPSS. The results showed an average reduction in sound pressure level of up to 12.67 dB and an absorption coefficient greater than 0.95. In addition, it had an average resistance of 1.75 MPa and maximum deformation of 60%, demonstrating that it is lightweight, efficient, and viable as a sustainable and competitive alternative.
