Course details

# Physics for Audio Engineering

IFAI FEEC BUT JFYZ Acad. year 2018/2019 Winter semester 6 credits

This course is a basic course of physics, focusing on areas usable in the sound technology. The first part is focused on the basics of particle mechanics, force and motion. The following areas are harmonic, damped and forced oscillations, then progressive and standing waves, the energy transmitted by waves, superposition and interference of waves. Physical fields are next areas which will be discussed. Gravitational field will be mentioned briefly. Electric and magnetic fields will be discussed in more detail, students will spend their formation, properties and basic laws and also generation of electromagnetic waves. This course will familiarize students with basic physical principles used in the measurement of non-electrical quantities by electrical methods. The last part of the course is focused on limits of classical physics and outline of their overcoming.

Subject specific learning outcomes and competences

The student is able to:
• Formulate the equation of motion and use it to solve the motion of point particles and rigid bodies and their systems,
• apply the laws of conservation of energy and momentum in the description of physical processes,
• formulate the equation of oscillating motion,
• describe harmonic, damped and forced oscillations,
• explain the formation of progressive and standing waves,
• describe the phenomena of superposition and interference of waves,
• describe the basic properties of sound waves,
• describe the basic properties of physical fields,
• describe the gravitational field,
• describe the formation of electric and magnetic fields, explain the relation between variables and describe methods of their measurement,
• describe the origin and basic properties of electromagnetic waves,
• explain the principles of measurement of selected non-electrical quantities,
• discuss the fundamental problems of classical physics and the possibility of overcoming them.

Learning objectives

The aim of the course is to provide students with a clear and logical interpretation of the basic physical concepts and laws focusing on areas utilized in the audio technology. There are mainly a particle mechanics, oscillations, waves, electric and magnetic fields. Understanding of these concepts and laws will be strengthened through a wide range of interesting applications. Practical knowledge will be verified in the laboratory exercises.

Prerequisite kwnowledge and skills

The student who enrols in the course should be able to use the Cartesian coordinate system and the graphical representation of the functions. He should be able to manipulate physical quantities, units and equations. He should be able to use mathematical apparatus at the level of basic work with vectors, linear equations, trigonometric, exponential and power law functions.
