Environmental impact study, sound measurement, limitation and acoustic monitoring for concerts, festivals and outdoor events.
Sanction prevention (Law 37/2003, RD 1367/2007) through prior environmental impact studies and real-time sound level control. Madrid and across Spain.
Our services
We cover every phase of noise control at your event: from the preliminary study to the final report.
Electroacoustic modelling with EASE and immission study with CadnaA. Prediction of noise levels in residential areas to comply with applicable regulations.
Measurements with our own equipment in the audience area and nearby facades. Continuous recording throughout the event for monitoring and correction.
Approved limiters on sound systems to control permitted levels, with recording as compliance certification.
Measurement data analysis and recordings for event evaluation. Technical reports for appeals in case of sanctions.
Electroacoustic model
The increase in concerts and shows in open spaces has heightened awareness about noise pollution in nearby residential areas.
Spanish Law 37/2003 and RD 1367/2007 establish the acoustic quality standards that must be met. A prior environmental acoustic impact study indicates which location, setup and levels are most appropriate to avoid nuisance and sanctions from authorities. The steps to achieve these objectives are:
Detailed description of the event: location, size, sound systems and technical characteristics.
Assessment of potential environmental, social and economic impacts of the event on the area.
Study of different setup configurations and orientations to minimise environmental impact.
Proposal of specific measures to minimise the identified negative impacts.
Coordination with organisers, local authorities and stakeholders.
Complete documentation with all information for review by the relevant parties.
Methodology
Each project phase follows a technical rigour that ensures accurate results and valid documentation.
Electroacoustic study
Using EASE software, sound sources are modelled with directivity and coverage adjusted in the audience area to obtain the most accurate assessment of the levels to be applied.
This study allows us to adjust levels and coverage to achieve the lowest noise emission in nearby dwellings.
Study area model
System directivity
Environmental study
Using the approved CadnaA software, the environmental impact study is carried out in nearby residential areas to comply with applicable noise regulations.
Noise immission in the study area with level graphs at ground level and at dwelling facades.
Study results
Graphic visualisation of predicted noise levels at ground level and on the facades of nearby dwellings. These maps allow identification of the most affected areas and adjustment of the sound system design accordingly.
Monitoring and measurement
Measurements are taken in the audience area and on nearby facades during both the sound system setup and the event itself.
Using our own measurement systems, continuous recordings are made for monitoring and to take corrective action if necessary.
Source limitation
Installation of approved limiters to control sound systems to permitted levels, with recording as compliance certification.
Analysis and report
Analysis of measurement data and recordings for overall evaluation of the event.
Creation of a detailed technical report valid for appeals in case of sanctions.
Applications
Experience in all types of outdoor events and venues with acoustic impact.
Acoustic emission control at concerts and performances in parks, squares and open venues.
Multi-stage acoustic management with simultaneous monitoring of multiple sound sources over several days.
Sound control at presentations, conventions and business events with amplification systems.
Noise management at local festivals and municipal events with impact on residential areas.
Sound level monitoring at sporting events with public address and entertainment systems.
Acoustic control at outdoor performances and shows with sound effects.

Frequently asked questions
Is an acoustic impact study mandatory for a concert?
It depends on local regulations. In many cities, the council requires an environmental impact study as a prerequisite for granting the event activity licence. In any case, having one is the best way to prevent sanctions.
What software is used for the studies?
We use EASE (Enhanced Acoustic Simulator for Engineers) for electroacoustic modelling of sound sources, and CadnaA (Computer Aided Noise Abatement) for environmental impact studies in residential areas. Both are industry-standard approved software.
How far in advance should the study be requested?
We recommend a minimum of 2-4 weeks before the event to carry out the electroacoustic study, the environmental study and prepare the complete documentation for the authorities.
What happens if limits are exceeded during the event?
Our measurement system detects any exceedance in real time. The monitoring staff can instruct the sound engineer on the necessary correction. Additionally, the installed limiters prevent levels from exceeding the established thresholds.
Can the technical report be used to appeal sanctions?
Yes. The report includes all time-stamped measurement data, the configurations used, acoustic dispersion maps and compliance documentation. It is a valid technical document for submission as evidence in administrative appeals.
Can measurement alone be hired without the prior study?
Yes. We offer each service independently: electroacoustic study, environmental study, event measurement and monitoring, limiter installation and report preparation. You can contract only what you need.
