ACOUSTICS ANALYSIS

Acoustics Analysis (formerly Acústica Arquitectónica S.A.) is a Spanish acoustic testing laboratory that has specialized in architectural, environmental and industrial acoustics since 1999. Operating from purpose-built premises in Berriozar, Navarra (Pol. Ind. Berrianz, Calle C, Nave 103, 31013 Berriozar), the laboratory serves clients across Navarra, La Rioja, the Basque Country, Aragón and Madrid. Its core mission is to help architects, engineers, building owners, businesses and public administrations diagnose and resolve noise problems through rigorous on-site measurement and accredited laboratory testing. As the laboratory itself puts it, "if you have any problem related to noise, we advise you."

The laboratory is accredited by ENAC (Entidad Nacional de Acreditación, the Spanish national accreditation body) for acoustic measurements under ISO/IEC 17025, the international standard for the competence of testing and calibration laboratories. This accreditation underpins the credibility of its results for regulatory compliance, expert reports and certification, and distinguishes it from non-accredited acoustic consultants. Tests are performed in accordance with the relevant Spanish and European standards, giving its reports legal standing for Building Code (Código Técnico de la Edificación, CTE) compliance and for environmental and industrial noise regulation.

The laboratory's testing portfolio centres on acoustic insulation, where it measures airborne sound insulation and impact (footstep) noise insulation of building elements such as façades, partitions, party walls and floors, as well as the acoustic insulation of installations. These measurements follow standards including UNE-EN ISO 16283-1 (airborne sound insulation), UNE-EN ISO 16283-2 (impact sound insulation) and UNE-EN ISO 16283-3 (façade insulation), together with the predecessor methods UNE-EN ISO 140-4 and UNE-EN ISO 140-7. Reverberation time and room acoustic conditioning are evaluated under ISO 3382-1 to assess acoustic comfort and intelligibility in spaces.

Beyond building acoustics, the laboratory carries out environmental and industrial noise assessment, including emission and immission sound-level measurements, sound mapping and the prediction of expected noise levels in a given environment. Environmental noise is measured following UNE-EN ISO 1996-2. The lab also determines the sound power of machinery and equipment using sound-pressure methods (UNE-EN ISO 3744, 3745 and 3746) and the sound-intensity method (UNE-EN ISO 9614-1), supporting manufacturers and industrial operators in characterizing noise sources and demonstrating regulatory compliance.

The laboratory applies advanced diagnostic techniques to pinpoint and visualize noise sources. These include acoustic intensimetry for the multimedia visualization of dominant noise contributions, acoustic photography (acoustic camera imaging) for the visual identification of where sound originates, and vibration measurement to characterize vibration transmitted from installations and from transport infrastructure. For long-term problems it offers extended sound monitoring, with measurement campaigns that can run for days, weeks or months to capture the full temporal profile of a noise issue.

A notable capability is the laboratory's own state-of-the-art testing facilities in Berriozar. These include coupled transmission and reception rooms for laboratory measurement of airborne and impact sound insulation of construction elements and products, as well as anechoic and semi-anechoic chambers for controlled sound-level and sound-power measurement. This combination of accredited in-situ field testing and dedicated laboratory chambers allows the company to test both finished buildings and the acoustic performance of materials, systems and equipment under repeatable conditions.

Typical field measurements take between one and four hours depending on the type of test, the number of rooms involved and access to neighbouring properties, while monitoring projects extend over much longer periods. The laboratory frequently works on practical projects such as soundproofing gyms and fitness centres, controlling noise from cafés, bars and nightclubs, and preparing acoustic studies required for CTE building-licence compliance, making it a hands-on partner for businesses needing to meet municipal and national noise limits.

With more than two decades of specialization, ENAC/ISO 17025 accreditation, a comprehensive suite of standardized test methods, and purpose-built laboratory chambers, Acoustics Analysis is a credible testing partner for architectural, environmental and industrial acoustics in northern Spain.
