Acoustics

The Acoustic Audit is a concept defined in Law 7/2002 on Protection against Noise Pollution of December 3, 2007 of the Generalitat Valenciana and Decree 266/2004 of December 3, of the Consell de la Generalitat, by which The rules for the prevention and correction of noise pollution are established in relation to activities, facilities, buildings, works and services. It consists of carrying out a control of acoustic emissions, levels of insulation and reception in the environment, of any activity likely to generate noise and/or vibrations.

Eurocontrol's acoustic testing laboratory carries out a wide range of on-site acoustic tests in the field of environmental and building acoustics. The reliability of the same, together with the efficiency in the provision of the service are the main values that make us the best choice to carry out measurements for requirements of the Administration, acoustic certifications of buildings, etc.

Eurocontrol evaluates and guarantees the independence and impartiality of the personnel who carry out the acoustic tests.

The social cost of noise is estimated to be several billion euros per year. This cost includes the harmful effects of noise on people's health as well as property depreciation due to poor sound insulation.
Developments in recent years in terms of environmental regulations and certification have also brought the issue of acoustics to the heart of projects.
From acoustic studies of new or existing structures to the management of noise in the external environment, engineering and consulting in the field of acoustics make it possible to carry out global impact studies and to certify the acoustics of buildings.

Study of the location of sound sources and acoustic bridges through the use of a sound camera. This technology locates the foci visually through photographs or videos with color representation based on the sound contribution of the visualized focus. This allows knowing the importance and situation of industrial or other types of noise sources, as well as the noise level emitted by the localized emission point.

The intelligibility of an emergency announcement in a public space can be crucial for those present, i.e. whether or not the message is clearly understood. This applies in particular to railway stations and airports, congress and shopping centres, stadiums, conference rooms and classrooms, etc.

To ensure good speech intelligibility, an objective measurement process is needed that gives relevant and reproducible results. The measurement of the Speech Transmission Index (STI) is one such process.

According to the WHO, noise is the second most important environmental risk factor in Europe after air pollution, causing hearing effects such as communication breakdown and hearing loss.
Inside a building, excessive noise can have very detrimental effects on the comfort and health of the people who work or live there. The same is true for any infrastructure or activity that generates noise and is close to populated areas.
The objective of the acoustic diagnosis is to determine the sound and acoustic quality of the analysed element and, if necessary, to propose the necessary measures against noise in order to comply with existing regulations and to improve people's hearing comfort.
