monitorAt dBplus acoustic consultants we have the perfect technology to accurately assess any acoustic problem. Our Engineering Department is made up of a highly qualified team that, using the latest technological tools, offer personalised solutions adapted to the particular needs of each client.


Prediction and simulation of on-site sound behaviour

At dBplus acoustic consultants we use specialised software for the simulation and prediction of sound behaviour indoors. For this, we analyse existing noise sources by contrasting measurements and technical data; we enter the geometric characteristics of the room and materials into the software. From this data, we create sound maps of the area in question, as well as the parameters that define the quality of sound (such as reverberation, intelligibility, definition and clarity). From these models, we can analyse the measures that need to be taken, according to the client‘s requirements, whether that be noise reduction solutions or materials that will improve the acoustic quality of the space.


dBplus acoustic consultants is a pioneering company working in the creation of acoustic prediction models for business premises, dedicated to the protection of employees from noise exposure risks. We use the latest technology to solve the different problems that can arise from excessive noise levels on business premises. We create sound maps that accurately reflect both the existing noise exposure levels and the potential for improvement by implementing a tailor-made solution.

Analysis and processing of environmental noise measurements

dBplus acoustic consultants have the most up-to-date technology available on the market for measurement, analysis and data processing; thereby guaranteeing the reliability and quality of the sound tests that we carry out. Using these specific programs, we process the data collected from the measurements in order to accurately define the parameters of the situation in question. This enables us to, amongst other things, eliminate random, unwanted noise or identify intermittent noise using long term measurements.

All of our measurement equipment complies with current legislation, periodic tests and criteria set by the Spanish Ministerial Order, dated 16th December 1998 of the Ministerio de Fomento
(BOE. 311 from 29/12/1998) and the Order dated 30th of June 1999 of the Departamento de Industria, Comercio y Turismo (DOGC 2928 from 12/07/1999).

Prediction of airborne and impact sound insulation in building elements

In room acoustics, one of the most important factors is the sound insulation of an architectural element, in terms of the capacity of the element to resist vibration produced in the space where the noise is emitted. Currently, minimum recommended insulation levels are defined by the applicable regulations in the field of acoustics. It is, therefore, necessary to use tools that enable us to accurately design airborne and impact sound insulation solutions.

dBplus acoustic consultants has the most up-to-date calculation software, which allows us to predict the effectiveness of the applied solutions to ceilings, walls, floors, roofs and windows. All assessments are undertaken following the quality procedures set out in UNE EN ISO 717-1 y 717-2 regulations, guaranteeing compliance with the prescribed objectives of the relevant standards and regulations.

Prediction and simulation of outdoor sound propagation

At dBplus acoustic consultants we have specialised programs for the simulation and prediction of sound behaviour outdoors. Starting with the geographical plans of the area in question, we identify the sources of noise and their behaviour using internationally-used noise emission and propagation models for road traffic (methods Guide du Bruit y NMPB-Routes), railway (method SMR-II), airborne (method ECAC.CEAC Doc.29) and industial noise (standards ISO 8297 y 9613). From the data input, we create sound maps that show the noise generated by sources in a specific area. From these, we can then test the corrective measures needed according to individual client’s requirements.

Using this type of program, we undertake noise impact assessments for a variety of activities and infrastructure, obtaining accurate results with the guarantee of compliance with the prescribed limits set out in standards and regulations in the field of environmental acoustics.

Measurement equipment and analysis of sound transmission via solid state mediums

Sound insulation between two premises not only depends on the sound insulation of the separating elements but also the indirect transmission paths that exist in a variety of building structures. Therefore, sound may be transmitted from one premises to another due to the separating element (direct path) or via the walls, ceilings or shared floors (indirect path).

With our solid state sound and vibration transmission measuring equipment, we identify the loss of sound insulation for each path independently and therefore assess the need to reinforce each one. In this way, sound insulation is optimised with the most suitable solution for the separating elements and respective indirect paths; thereby achieving maximum effectiveness in noise transmission reduction whilst minimising the investment of time and money.
