Quality control in construction: Verification of compliance with building acoustic regulations in Spain through field measurements
Year: 2025
Type: article
Abstract: In Spain, the Basic Document DB HR Protection against Noise outlines acoustic regulations for buildings. Acoustic testing is not mandatory nationwide, but several regions and local governments require testing the sound insulation of walls, floors, and facades, as well as the sound pressure levels of building services, to obtain the first occupation license. This license is integrated into the final stage of the construction process in Spain, confirming the building’s completion and that it is safe and habitable. This paper aims to analyze the regional decrees in Spain that require mandatory acoustic testing before occupancy. Specifically, information on test sampling and other procedures will be presented. The regulations concerning different types of acoustic testing and the required sampling rates have been analyzed across several autonomous communities and major cities in Spain, alongside an examination of the Spanish acoustic classification scheme. A comparison was made to evaluate the minimum number of mandatory tests required for various acoustical characteristics. Additionally, a practical example is provided, illustrating the sampling rates and comparing the resulting number of measurements required. Although some local regulations share criteria on sampling, such as testing 10% of dwellings or using the square root of the number of dwellings, this study found it challenging to interpret the ordinances and apply them to a specific case, as many issues are left to the technician’s discretion. It would be ideal for criteria and sampling procedures to be harmonized and implemented uniformly at the national level.
