Sound Laboratory I

Knowledge of 9th grade physics and mathematics.

The methodology used is defined by the following items:

a) presentation of programmatic contents using new information and communication technologies;
b) systematization of theoretical and practical knowledge: resolution of issues and problems;
c) laboratory experiments and demonstrations in the classroom performed by the teacher and students with specialized hardware and software.

Students may choose between two types of assessment: continuous/periodic assessment or exam. The continuous/periodic assessment will focus on acoustic experiments and demonstrations, and class participation (20%) + test (80%). The assessment by exam (100%) will be made through written and oral test (the latter, if the classification in the written test is between 7,5 and 9,4 values).

The learning outcomes of this curricular unit are:

a) know the sound and its characteristics;
b) identify the various forms of sound production;
c) understand the role of the various components and properties related to sound propagation;
d) know acoustic phenomena applied to day-to-day situations;
e) know the sound Fields: sound outdoors and indoors;
f) know the human auditory system and the hearing process;
g) identify the physical and psychological characteristics of sound;
h) know how to choose music for the media.
