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

To understand how simple and complex oscillatory systems work and their application to the musical instruments. To know the most relevant acoustic characteristics of the different musical instruments as well as the main methods and approaches for their analysis.

Syllabus:

Harmonic oscillator and the Helmholtz resonator. Forced regime and resonance frequencies. Chordophones: Wave equation and general wave solutions. Propagating and standing waves. Reflection at fixed and free ends. Forced regime. Wave number. Fundamental wave relationship. Power relations. Resonance and anti-resonance frequencies. Natural vibration frequencies and modes: frequency, intensity, timbre, spectrum, fundamental, partials. Vibration energy of the natural modes. Fourier analysis. Aerophones: open and closed ends. Natural frequencies and modes. Membranophones: rectangular and circular membranes. Natural frequencies and modes. Spectral analysis and synthesis. Music concepts: loudness, pitch and timbre.

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 the systematic and organized expository presentation of information through reflection, critical analysis and research suggested by the teacher, complemented with its study and discussion and with the guidance and supervision of the process of acquiring knowledge and skills provided for in the objectives of the UC - Classes with a large component of exercises solved and applied to room acoustics. Several practical works are carried out by the students in order to cement the knowledge acquired in class. Group / Class. This UC is given to a class in group classes. The evaluation process is based on the observation of the quality of participation in the activities developed during the teaching of the course, including presentations and discussion of works, other tests, tests or exams, verifying the degree of acquisition of the knowledge and skills acquired foreseen in the objectives from UC CONTINUOUS EVALUATION AF = Tx0.5 + TRABx0.4 + PARTx0.1 AF - Final Evaluation TRAB – Trabalhos práticos. PART – participação nas aulas. Máximo de faltas para ter aproveitamento na avaliação contínua: 3 (exceto trabalhadores estudantes). Os estudantes que tenham reprovado no Teste Final escrito inserido na avaliação contínua podem realizar um Teste de Recuperação na Época de Exames.

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

The teaching methodology will be based on the transfer of theoretical and practical concepts through the intensive use of classes with exercises and practical problems and case studies (real), as well as classes of experimental work. All the concepts and fundamentals presented in the UC program are widely discussed with students in class, seeking, whenever possible, to show the application of concepts to real cases known by students. In this way, it is possible to satisfy the objective of making known all the concepts related to musical acoustics, in particular. The coherence of teaching methodologies with the learning objectives is measured through the performance and evolution of the student in class, and the result of practical work and tests or exams.
