The Problem

Portugal has a noise problem, and most people accept it as inevitable. Walk through any Portuguese apartment building from the 1970s-2000s and you'll hear everything: the neighbor's TV, footsteps above, plumbing from three floors up, and traffic from the street. The construction quality of most Portuguese residential buildings, particularly those built during the rapid urbanization of the 1970s-1990s, prioritized speed and cost over acoustic comfort.

The numbers are striking:

• Eurostat Quality of Life survey: 25-30% of Portuguese residents report being affected by noise from neighbors or the street — higher than the EU average of ~18%.
• Pre-RRAE buildings: The Regulamento dos Requisitos Acústicos dos Edifícios (Decree-Law 96/2008) only became strictly enforced for new construction from ~2008. An estimated 70% of Portuguese housing stock was built before effective acoustic regulation.
• Tourism noise: In Lisbon (especially Alfama, Bairro Alto, Santos), Porto (Ribeira, Cedofeita), and Algarve towns, Alojamento Local tourism has transformed quiet residential areas into noise hotspots — tuk-tuks, late-night tourists, bar noise.
• Remote work: With 15-20% of Portuguese workers now working from home at least part-time (INE labor force survey), home office noise is a productivity killer.

The problem is well-documented and widely felt, yet almost nobody in Portugal specializes in acoustic solutions for existing buildings. General contractors don't understand acoustics. Architects focus on new construction. Homeowners are left Googling and DIY-ing with dubious results.
