Objectives
The students will acquire a deep knowledge of the instrumentation used in acoustic measurements. The students will learn about the different types of noises and be able to deal with current regulations concerning acoustic noise. Additionally, they will acquire abilities regarding the different methods of acoustic noise control, both active and passive.
Skills and learning outcomes
CB1: Students have demonstrated possession and understanding of knowledge in an area of study that builds on the foundation of general secondary education, and is usually at a level that, while relying on advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study. CB2: Students are able to apply their knowledge to their work or vocation in a professional manner and possess the competences usually demonstrated through the development and defence of arguments and problem solving within their field of study. ETEGISA3: Ability to develop projects for locales and installations, aimed at production and recording of audio and video signals. ETEGISA4: Ability to implement acoustic engineering projects for the following: acoustic conditioning and insulation for locales; PA system installation; specification, analysis and selection of electroacoustic transducers; measurement, analysis and control systems for sound and vibrations; environmental acoustics; underwater acoustics systems. RA1: To acquire the knowledge and understanding of the general basic fundamentals of engineering, as well as, in particular, of multimedia communications networks and services, audio and video signal processing, room acoustic control, distributed multimedia systems and interactive multimedia applications specific to Sound and Image Engineering within the telecommunications family. RA3: To be competent to carry out engineering designs in their field within Sound and Image Engineering, working as a team. Design encompasses devices, processes, methods and objects, and specifications that are broader than strictly technical, including social awareness, health and safety, environmental and commercial considerations. RA4: To be able to carry out research and carry out innovative contributions in the field of Sound and Image Engineering, including bibliographic search and comprehension as well as the design and development of experiments that solve the challenges of knowledge in the field of audiovisual systems, in terms of the capture, processing, adaptation, diffusion and consumption of multimedia contents, as well as associated networks, services and applications, which justifies the scientific interest of this Degree. RA5: Be competent to apply the knowledge acquired to solve problems and design audiovisual networks and services, to configure their devices, as well as to deploy adaptive, personal audiovisual applications and services on them, bringing network intelligence to the value for the user, maximising the potential of multimedia networks and services in the different social and economic spheres, knowing the environmental, commercial and industrial implications of the practice of engineering in accordance with professional ethics.

Measurement microphones. 6.- Sound sources: power and omni-directionality criteria. Tapping machine. 7.- Sound level meters and acoustic analyzers.
Learning activities and methodology
Two teaching activities are proposed: theoretical classes and guided projects. THEORETICAL CLASSES The theoretical class will be given in the blackboard, with slides or by any other means to illustrate the concepts of the lectures. In these classes the explanation will be completed with examples of technical specs for acoustic instrumentation and references to current regulations. In these sessions the student will acquire the basic concepts of the course. The students will have to work on the explained concepts, working out and solving the proposed assignments in order to consolidate the concepts of the course. GUIDED PROJECTS The students, working in small groups, will carry out a guided project consisting of a realistic simulation of a noise control system. To this end, the students will have to study the specific problematics, assess different solutions, and describe the chosen one. The students will be given a detailed guide and some specific tutoring. LABORATORY EXERCICES Laboratory exercices aims to familarize the student with acoustic measurements employing proffesional instruments. In this way, the students will consolidate the theoretical concepts and learn a metodology to develop different kinds of acoustic measurements.
