Abstract: This study evaluated the acoustic performance of impact noise in prefabricated ribbed slabs with prestressed joists, using vinyl flooring as a covering and testing the efficiency of floating floors with different resilient materials. The tests were carried out by the Brazilian standards ABNT ISO 16283-2 and ISO 717-2 to determine the standard weighted impact sound pressure level (L'nT,w) in each composition tested to check that they met the minimum requirements of the Brazilian performance standard ABNT NBR 15.575-3. As a result, of the 13 vinyl flooring samples studied in the 4 cm subfloor system, only one did not satisfy the minimum requirements (82 dB). At the same time, eleven were classified at the minimum level, ranging from 67 to 80 dB, and one at the intermediate level (64 dB). Based on these results, six samples were selected for testing with the floating floor system solution using nine resilient materials. Most of the compositions showed intermediate performance levels, ranging from 62 to 56 dB, with 23 samples having a higher level (≤ 55 dB).
