This study addresses the critical gap in Ecuador’s regulatory framework regarding acoustic insulation in buildings by developing a comprehensive guide for integration into the Ecuadorian Construction Standard (NEC). While Ecuador has some regulations attempting to control noise pollution aspects, there remains a significant knowledge deficit concerning long-term noise exposure effects. Our research analyzes common construction elements in Ecuador, evaluates their acoustic performance through computational simulation based on the UNE-EN ISO 12354-1 standard, and proposes practical solutions adapted to local materials and techniques. A comparative analysis with Spain’s Technical Building Code (CTE) provided methodological framework for developing acoustic recommendations. Results reveal that Ecuadorian construction materials typically have higher densities than Spanish counterparts, offering potentially superior acoustic properties following the mass law. Traditional brick constructions showed sound reduction indices (R \(_A\) ) of 44–49 dBA versus 33–40 dBA for similar Spanish systems. The research culminates in a detailed acoustic protection guide for vertical partitions, facades, and horizontal floor systems that can be incorporated into the NEC. This contribution advances building acoustic standards in Ecuador and establishes a foundation for future regulatory development in noise protection, ultimately improving occupant health and comfort in Ecuadorian buildings.

摘要

This study addresses the critical gap in Ecuador’s regulatory framework regarding acoustic insulation in buildings by developing a comprehensive guide for integration into the Ecuadorian Construction Standard (NEC). While Ecuador has some regulations attempting to control noise pollution aspects, there remains a significant knowledge deficit concerning long-term noise exposure effects. Our research analyzes common construction elements in Ecuador, evaluates their acoustic performance through computational simulation based on the UNE-EN ISO 12354-1 standard, and proposes practical solutions adapted to local materials and techniques. A comparative analysis with Spain’s Technical Building Code (CTE) provided methodological framework for developing acoustic recommendations. Results reveal that Ecuadorian construction materials typically have higher densities than Spanish counterparts, offering potentially superior acoustic properties following the mass law. Traditional brick constructions showed sound reduction indices (R \(_A\) ) of 44–49 dBA versus 33–40 dBA for similar Spanish systems. The research culminates in a detailed acoustic protection guide for vertical partitions, facades, and horizontal floor systems that can be incorporated into the NEC. This contribution advances building acoustic standards in Ecuador and establishes a foundation for future regulatory development in noise protection, ultimately improving occupant health and comfort in Ecuadorian buildings.
