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 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.
CONTINGENCY PLAN BEFORE THE SITUATION GENERATED BY COVID-19:
The recommendations contained in the Agreement of the Faculty of Optics and Optimetry of 7/15/2020 relating to the teaching of the course 2020/21 would be followed
The above information will be valid as long as Scenario 1 (face-to-face expository teaching, reduction of practice groups to 50%, completing teaching with online content), considered by the USC persists.
In the event that we were in Scenario 2 (face-to-face and telematic teaching in alternate sessions, with reduction of groups to 50%, reduction of practice groups to 50%, completing the teaching with online content), non-face-to-face theoretical teaching (preferably synchronous, but being asynchronous for unsuccessful causes) would be taught using the tools that the USC has available to students and teachers (virtual USC, Tems, Email etc.) The same conditions would be maintained as in scenario 1: the only change in the evaluation would be the suppression of the need to achieve a minimum grade of 3.5 points in the final exam and 1.5 points in the continuous evaluation. The rest of the evaluation would not change, since in this scenario and given the characteristics of the subject (which include the use of computer programs to carry out the practices), the students could complete the requirements of the subject without problem. The final exam would be preferably face-to-face, unless particular circumstances prevent it. In that case, institutional tools such as Office 365, Moodle or other aer available ones would be used.
In scenario 3 (telematic teaching), teaching would be non-face-to-face (preferably synchronous, but could be asynchronous due to supervening causes) using the tools that the USC has available to students and teachers (virtual USC, Teams, Email, etc.). The same conditions would be maintained as in scenario 1: the only change in the evaluation would be the suppression of the need to achieve a minimum grade of 3.5 points in the final exam and 1.5 points in the continuous evaluation. The rest of the evaluation would not change, since in this scenario and given the characteristics of the subject (which include the use of computer programs to carry out the practices), the students could complete the requirements of the subject without problem. The final exam would preferably be non-face-to-face (institutional tools such as Office 365, Moodle or others available would be used), unless particular circumstances prevent it.
In the case of fraudulent exercises or exams, the provisions of the "Regulations for the assessment of students' academic performance and the revision of qualifications" will apply.
