How to acoustically classify residential buildings



25 November 2021




10:00 am - 11:00 am



The Spanish Technical Building Code sets the minimum protection against noise fitted in the homes built in the Basque Country and in Spain since 2009.

However, when attempting to assess the acoustic status of a building or household beyond compliance with the regulatory minimum, one should resort to other explicit and consensual assessment systems. The acoustic classification schemes comply with this function by establishing different levels of acoustic quality.

In the vast majority of European countries, there are acoustic classification schemes for dwellings associated with the acoustic prescribers used in each country. Over the last few years, work has been carried out throughout Spain to develop a specific acoustic classification scheme.

  • As a result of this effort, the UNE 74201 standard was published in September 2021. Acoustics. Buildings acoustic classification scheme.


This sessions will provide an overview of the buildings acoustic classification schemes and their application, focusing on the classification system established in the UNE 74201 standard and, more specifically:

  • What are the acoustic characteristics, criteria, and ranges considered by the acoustic classification schemes?
  • What is the process for classifying a building?

This session is part of the collaboration agreement between the Basque Department for the Environment, Territorial Planning and Housing and TECNALIA to research, innovate and promote acoustic quality in the residential construction industry of the Basque Country.

Aimed at:

  • Developers, construction companies and administrations
  • Professional societies and universities
  • Architects and town planners


  • Maria José de Rozas, head of the Acoustics Division of LCCE of the Basque Government, co-managed by TECNALIA.
