The purpose of this thesis was to determine the percentages of Acoustic Absorption of three different walls. A 0.30 m long, 0.15 m wide and 5.8 cm thick Fibrocement and Laminated Gypsum Wall was built with an internal aluminum structure. Before starting the filling process, the Acoustic Absorption coefficient of all materials was calculated with a Sound Level Meter, and a sound source at a single frequency of 686.9 Hz. Fibrocement plates of 0.7 cm thickness, Gypsum Laminate of 1.6 cm of thickness and Corrugated Cardboard of 0.4 cm of thickness to 0.30 m of length by 0.15 m of width; In turn different thicknesses were generated from one plate, then the others were glued to thicknesses of 10 of them. For the Multi-sheet wrinkled Extensible Paper of three layers the thicknesses varied from two to ten cm; cutting these to an approximate one fourth of the original bags. A thickness of both materials was chosen as a filler from the wall originally constructed and data were taken with a sound level meter to observe the percentage of Acoustic Absorption of each of the three walls mentioned initially. In this investigation, approximately 1400 tests took place; with the following results: The wall filled with Corrugated Cardboard presented 25% of Acoustic Absorption in relation to the wall filled with Multi-sheet wrinkled Extensible Paper and the wall without filling which had a 24% and 22% of Acoustic Absorption respectively. Regarding the Acoustic Absorption coefficient, it was obtained that the Multi-sheet wrinkled Extensible Paper and Corrugated Cardboard presented an increasing relation with respect to the thickness of the materials unlike the Plates of Fibrocement and laminated Plaster that showed an increasing and decreasing relation as we increased the thickness of the plates. The averages Acoustic Absorption coefficients with respect to material thicknesses were: 0.25 for Laminated Gypsum, 0.25 for Multi-sheet wrinkled Extensible Paper, 0.23 for Corrugated Cardboard and 0.22 for Fibrocement.
