- to know what is an acoustic wave and the magnitudes that represent her - to understand the level concept of pressure and to be able to realize basic operations with the sonorous levels (composition of waves and spread) - handle the basic concepts of the acústica of enclosures (Resonance and reverberation) - to learn to use the basic tools of digital analysis of the sound (concept of spectrum, spectrum in bands of frequency and leaked of the acoustic sign) - to know the articulatory, acoustic and auditory properties of the phonemes - to know the acoustic properties of the hearing and the fundamental concepts of psicoacústica
UNIT 1 - Introduction to acoustic waves
What is an acoustic wave. Magnitudes. Wave propagation in a medium. Characteristics of harmonic waves. Characteristics of complex waveforms. Spectrum of a waveform. Intensity and acoustic impedance. Plane waves and spherical.
ITEM 2 - Overlay and wave propagation
Sound power source. Superposition of sound waves. Attenuation of sound in the middle. Loss level with distance.
ITEM 3 - Acoustic enclosures. Resonance and reverberation
Reflection and transmission between 2 means. Resonance in pipes. Resonance in complex waveforms. Sound indoors. Reverb and its consequences. Estimated reverberation time.
ITEM 4 - Analysis of sound
Digital signals. Acoustic signal filtering: filter types. Sound analysis in frequency bands (octave and third octave). Sound pressure level complex. S / N ratio. Types of noise used in acoustics.
ITEM 5 - Acoustic Phonetics
Articulatory classification of phonemes. Acoustic properties of phonemes. Auditory identification of phonemes
ITEM 6 - Acoustics physiological and psychological
Acoustic properties of the ear. Mechanism of hearing. Levels of noise. Tone. Ring. Masking. Binaural hearing.
The practical issues to be presented to students will relate to some interesting aspects of acoustic applications such as speech intelligibility, signal conditioning and room acoustics, performing demonstrations also hearing relating to such applications.For these practices, a sound modeling program will be used.
Theoretical contents (13h)
Practical contents (13h)
Given the shortage of textbooks of acoustics in Spanish, some of the books available in this bibliography are in English.

The course will have an important part of its development through the use of the Virtual Campus. All information provided to the student in class will also be available through the website of the course, including content presentation, material problems, practices, and links to Internet content and communication with the student. It is important that the student makes regular monitoring of the signature page.
The 13 hours of lectures will present the fundamental concepts of the subject, including representative examples of the practical aspects that students must master. These contents will be the basis for the presentation of practical issues. The practical issues shall consist of a series of works that the student should be performed using the concepts explained in the lectures. These issues include highly practical aspects that allow students to become proficient in handling techniques related acoustic signal conditioning, the speech intelligibility and the acoustic characteristics of enclosures. It will also include a series of demonstrations hearing in which students can perceive the effect of auditory processes studied both in theory and in practice.
SEE THE "OBSERVATIONS" SECTION BELOW
The final qualification for the course will consist of the sum of the qualification of the final exam (70%) and the qualification obtained in the continuous assessment (30%). The latter is obtained by submitting all relevant lab reports correctly made. Therefore, the final exam will be qualified with up to 7 points and lab reports with up to 3 points. You must obtain a minimum of 3.5 points on the final exam and a minimum of 1.5 points in qualification of lab reports to pass the course. Failure to submit a lab report will result in a failure to pass the continuous assessment and, therefore, to pass the subject.
In cases of fraudulent performance of exercises or tests, the provisions of the "Regulations for evaluating student academic performance and reviewing grades" will apply.

Total contact hours: 26
Hours of lectures: 13
Practical hours: 13
Total Non-contact hours: 26
For the correct understanding of the theoretical material each student must spend a minimum of 13 hours.
For the successful completion of lab reports the student will need a minimum of 13 hours.
This course is easy to carry by students, since all necessary information about the competencies expected of them and the means to acquire them will be perfectly defined as the subject will develop. These skills include simple aspects that students must master. The central idea is that students can deal with clear and simple concepts to permit it to extensive training to develop further contacts with the acoustic aspects to be found throughout his student life and professional in the field of audiometry and audiology . It is not know many things if you know the essential things and handle them safely.
To achieve this it is very important that students attend the classes, making it easier to realize the main aspects of the subject and save you study time.
Another fundamental aspect is that the student must interact with the teacher to resolve the doubts that appear during the course, particularly in the reports of practices.
