Fine-tuning acoustic isolation in buildings


Acciona Infrastructure, spain

In response to new technological developments, Acciona Infrastructure needed to increase competences and offerings for building acoustics and sound insulation in buildings.

Spain’s Acciona Infrastructure is ranked among the leading construction companies in the world. They are recognized for implementing advanced and innovative techniques and technology. R&D is vital to keep the company at the cutting edge. Acciona Infrastructure created a dedicated team to analyse building sound insulation in relation to technological developments in building construction.

Traditional acoustic isolation calculation methods are not always precise and often deviate from one another. The use of new materials and joining methods in buildings, plus the introduction of the Spanish Technical Building Code, CTE, inspired Acciona to carry out acoustic quality analysis on buildings. They hoped this would help them better understand the precise sound isolation required and to improve future designs.

For on-site building analysis, the team started with a Hand-held Analyzer Type 2250, Omnipower Sound Source Type 4292, and Tapping Machine Type 3207. As the research progressed and became more complex, the setup was upgraded to include a PULSE data acquisition and analysis system and LAN-XI data acquisition hardware.

The initial project has been very successful. Acciona is now able to perform more precise analysis of existing and new materials, as well as new structural concepts. Moreover, they are able to validate these models so that better isolation methods and composite materials can be created and structural dynamics can be continually improved.

Acciona Infrastructure

ACCIONA Infrastructure covers all aspects of construction from engineering to project execution and maintenance. This includes the management of public works awards, especially in the area of transport (roads, motorways) and building construction, among which the most significant projects have been hospital services and education centres.

The company works along two main lines of business – civil works and construction. Additionally, its organisational structure has special support units for the construction side, among which the most important units are the metal structures workshops, the machinery service, infrastructure maintenance, the facilities unit and the engineering unit, as well as various specialised auxiliary companies.

ACCIONA Infrastructure is part of the ACCIONA group, which is one of Spain’s principal business groups and a leader in the fields of infrastructure development and management, renewable energy, water and services.
