    Acoustic comfort is a key component of well-being in habitable spaces, particularly in industrialized timber housing, where lightweight structural systems present specific challenges for noise control. This study aims to propose design solutions to enhance airborne and impact sound insulation in prefabricated timber floor assemblies, based on a comparative analysis between Chilean regulations (NCh 352-1 and Article 4.1.6 of the OGUC) and Spanish standards (DB HR and UNE 74201), which provide a more comprehensive framework for acoustic performance requirements. Using a descriptive-experimental methodology, the research was structured in three stages: (1) regulatory review, (2) analysis of architectural-acoustic design strategies, and (3) design and simulation of optimized floor systems. Regulatory gaps in Chile were identified, particularly regarding prefabricated timber floors, as several configurations in the “Listado Oficial de Soluciones Constructivas - MINVU” do not consistently meet the minimum sound insulation criteria. As a result, four improved constructive solutions for timber platform floors were proposed, incorporating enhancements in both material selection and structural configuration. The solutions adopt strategies such as floating floors, resilient layers, and mechanical decoupling of elements to optimize acoustic performance. These configurations were evaluated through predictive simulations using INSUL software, applying performance benchmarks from the UNE standard (minimum 50 dB for airborne sound insulation and maximum 65 dB for impact sound level). The results demonstrate significant improvements in the acoustic performance of the proposed assemblies compared to the currently catalogued solutions, providing technical guidance for potential updates to local acoustic standards. In conclusion, this research contributes to strengthening constructive quality and acoustic comfort in industrialized timber housing, thereby supporting the sustainable development of the sector.
