Acoustics I

Use of tools for the development of skills in the context of research, auditory stimulus simulation programs and calculation tools
The course unit comprises:
– 1 TP class of 1h/week, to expose the programmatic contents of the discipline
– 1 T/P class of 1h/week, for application of concepts and mechanisms in problem solving
– 1 PL class of 1h/week, where students perform with laboratory activities.
The continuous evaluation:
1) reports of experimental activities (AE) to be resolved at each class (PL).
2) two written evaluation tests (PE1 + PE2) (TP).
The final score is the average of the classification at all times of assessment, ie:
Final grade = (AE + PE1 + PE2)/ 3, , in which PE represents the average of the classification obtained in the various
reports (AE), and PE1 and PE2 represents the evaluation obtained in the written evaluation tests.
The average of each component must be equal to or greater than 9 values

The discipline of Acoustics I aims to provide the Audiology students with a solid basis in the fundamental concepts of Acoustics necessary to achieve the general objectives inscribed in the training plan of the Audiology course of Coimbra Health School, with a special emphasis on general concepts necessary for the understanding of sound as a physical phenomenon, of acoustics applied to physiological systems , and the instrumentation found in Audiology, transmitting at the same time the fundamentals of mathematics and intellectual mechanisms of understanding and rigor underlying the scientific method.
