Acoustic and vibration engineering

Acoustical and vibration engineering is a technical branch that advocates for good management of noise at construction sites and infrastructures.

The goal is to prevent health problems resulting from noise and the negative consequences of unwanted vibrations at construction sites. The second affects machine design and the resonance they provoke.

Reducing noise at work

For many years, operators that work in construction and related sectors use workplace risk prevention systems to the reduce levels of noise to which they are exposed. A good example of this are earplugs and safety headphones. Since it is more and more common for nonconstruction-related personnel to come near the parameter of a construction site, it is common to see noise barriers or sound barriers on site: from tall walls to other types of innovations. They are also often placed on roads and highways, especially if a site is near a city.

Commitment to acoustical impact

When it comes to designing noise barriers, Ferrovial also makes use of vegetation barriers to protect plants, earth dams, partial covers and special devices. Special devices refers to elements that are used to reduce noise produced by viaduct expansion joints and plant construction work when, for example, vehicles drive on top of them.

Vehicles are one of the largest sources of urban noise. A high level of exposure to noise (in terms of decibels or duration) can provoke hearing problems, migraines, stress, cardiovascular problems and insomnia. That is why acoustical engineering is important during construction and infrastructure operation.

Acoustical engineering

We have a department specialized in acoustic engineering to comply with European regulations (Directive 2002/49/CE) and domestic regulations (Law 37/2003, 1513/2005 and 1367/2007). We have also obtained quality certificates for construction ISO 9001 and 14001.
