Learning Outcomes (knowledge, aptitudes and skills to be developed by the students)

Understand the fundamental concepts about the radiation, propagation and reception of noise in open and closed spaces to proceed with its management, assessment and control pursuing a good acoustic environment and acoustic Comfort. Understand the fundamental concepts underlying the acoustic insulation of building elements.

Syllabus:

Hearing mechanisms and human sound perception. Effects of noise on man. Pressure, particle velocity, plane, spherical and cylindrical waves. Sound pressure, intensity and power levels. Metrics. Level arithmetic. Correlated and non-correlated sources. Time and frequency descriptors. Constant and percentual width filters. Octave and 1/3 octave filters. Point and line sources. Physical phenomena in the sound propagation in the atmosphere: attenuations by divergence and air absorption, reflections, refractions and diffractions. Sound propagation in the atmosphere: General calculation procedure. ISO 9613. Legal framework. Room acoustics basics. Transmission coefficient and transmission loss. Transmission phenomena between 2 different mediums and between one medium separated by a second one. Model for a simple monolithic wall. The mass law. Heterogeneities. The coincidence frequency. Noise control measures and occupational noise.

Demonstration of the Articulation of the Programme Contents with the Objectives of the C.U.

Considering the objectives of this curricular unit, any expert in the field can conclude that all the syllabus points aim to give the students the competences and the required knowledge and skills to reach the learning outcomes.

Teaching and Evaluation Methods:

The teaching methodology is based on systematic and organized presentation of information through questioning, critical analysis and research, complemented with its study and discussion under the guidance and supervision of the teacher in order to ensure knowledge and skills acquisition process, as specified in the C.U. objectives - Theoretical-practical lessons having a substantial component of solved exercises being applied to the resolution of real problems practical issues. Students undertake practical work in order to consolidate the knowledge learned during the lessons. This curricular unit is given in a group class. Continuous Assessment: AF= T1x0.7+T2x0.7+TRABx0.2+PARTx0.1 AF - Final evaluation; T1 - 1st test; T2 - 2nd test; TRAB – Practical work; PART – participation in class. Maximum classroom lessons absences: 3 (except student workers). Students who have not completed the Continuous Assessment, or are disapproved by absences, may undertake the Examination in the Normal Season, and If they fail the Normal Season’s exam, they can still do an examination in the Appeal Season. The student who fails the Continuous Assessment may do the examination only during the Appeal Season.

Demonstration of the Articulation of the Teaching Methodologies with the Learning Objectives of the C.U.:

The teaching methodologies are based on the transfer of theoretical and practical concepts through the extensive use of practical exercises and case studies (real), together with classes where the students conduct experimental work. All the concepts and fundamentals presented in the syllabus are widely discussed with the students in the lessons, and, whenever possible, these concepts are applied to real situations that the students know by themselves. This way one can satisfy the objective that the students can learn all concepts related with noise and acoustic insulation, in practice. The coherence of the teaching methodologies with curricular unit’s objectives is measured by the performance and progress of students in the lessons, and in the results of the practical works and of the tests or exams.
