Semester 2 courses details¶

Compulsory courses¶

Numerical methods for acoustics¶

• Institution: ECL
• Coordinator: Didier DRAGNA
• Language: English
• Assessment: TODO
• Shared course: MSc. specific course

Objectives¶

This course aims at providing the basic knowledge required to successfully perform numerical simulations in the various fields of acoustics. For that, the main numerical methods used in industrial and research codes are presented. Simple but practical applications of these methods are then discussed. No prior knowledge is needed for this course.

Program¶

• Introduction: basic knowledge of linear acoustics
• Finite difference methods
• Integral formulation / Boundary element methods
• Finite element method
• Geometrical acoustics, ray tracing
• Propagation in inhomogeneous media: parabolic equation
• Conclusions and perspectives: overview of some hot topics in acoustics

Skills developed¶

At the end of the course, students will be able to: - Perform numerical simulations in simple configurations in various fields of acoustics - Master several numerical methods - Develop good habits for performing numerical simulations and interpreting results

Vibrations¶

• Institutions: ECL (Lecture & Tutorials) / INSA Lyon (Practicals)
• Coordinator: Claude INSERRA
• Language: English
• Assessment: continuing assessment + 1 written exam (50%), + Lab class reports (50%)
• Shared course: MSc. specific course

Objectives¶

Vibrations of mechanical systems are a major cause of sound radiation in our environment. The course therefore offers students the possibility to become familiar with the physics of vibrations as a prerequisite to vibroacoutics, that is the study of sound radiated by vibrating structures.

Program¶

Introduction to vibrations of mechanical systems, starting from the simple unidimensional oscillator to the multiple degree of freedom oscillations, before extended the lecture to the dynamics of continuous systems. This includes: - Basics of dynamic equation for discrete or continuous systems by energetic approach - Oscillation of a single degree of freedom oscillator, with or without damping, free or forced - Response to arbitrary excitations - Multiple degree of freedom oscillations - Vibrations of continuous system - Introduction to experimental modal analysis

Skills developed¶

• Grasp the concept of Eigen mode
• Formalize the set of equations associated to a mechanical system undergoing small deformations,
• Be able to derive the Eigen modes from the equations and to carry out a modal synthesis

Elective courses¶

3 ECTS have to be chosen among the following list:

Adaptive filtering: Application to Active Noise Control¶

• Institution: ECL
• Coordinator: Laurent BAKO
• Language: English
• Assessment: 1 written exam + 1 project with oral presentation
• Shared course: ECL elective course D2

Objectives¶

In recent years, adaptive filtering has found an increasing number of applications (echo cancellation in telephony, channel equalization in communication systems, denoising of bio-medical signals, ...). This course aims to discuss the basic principles, the scope of applicability, and the implementation aspects of adaptive filtering. The originality of the course resides in a multi-disciplinary treatment of the adaptive filtering problem going from the design methods (Signal Processing) to hardware implementation with embedded digital processors (Digital Electronics). A specific focus will be put on the problem of active noise control in Acoustics, a typical application of adaptive filtering.

• Design an active control system in all its dimensions: acoustic diagnosis, algorithm choice, DSP implementation
• Project by group of 5 students followed by an oral presentation.
• The work is based on experimental, on Matlab and Simulink programs.

Program¶

• Introduction to adaptive filtering
• Wiener filter and quadratic optimization
• LMS algorithm
• Architecture of DSPs
• Hardware implementation
• Introduction to Acoustics
• Passive noise control
• Active noise control and applications

Skills developed¶

• Understand the theory of adaptive filtering
• Apply adaptive filtering algorithms
• Explain the architecture of digital signal processors
• Implement adaptive filtering methods for active noise control

Finite Elements¶

• Institution: INSA Lyon
• Coordinator: Damien FABREGUE
• Language: English
• Assessment: project
• Shared course: INSA-GSM 4A

Objectives¶

This course is an introduction to Finite Elements calculus. The Objectives are: - To explain the principle of the finite element method applied to Mechanics, and the main difficulties occurring when solving problems. - To discover a finite element software. - To work in little group solving a problem using finite element method.

Program¶

• Introduction to finite elements calculation
• General presentation of the method, theoretical aspects
• Different types of elements
• Convergence, boundary conditions, non-linearity
• Practical damage
• Static calculations, in 2D and 3D Project by group of 2 or 3 students

Skills developed¶

• Master the theoretical bases of the finite element method.
• Use an industrial finite element calculation code (ABAQUS).
• Choose and implement a modelling strategy for a simple (linear) system.

2^nd Language¶

• Institution: INSA Lyon
• Coordinator: TODO
• Language: English
• Assessment: TODO
• Shared course: INSA Lyon

Objectives¶

For students who are not fluent in French, the French course (6 ECTS) replace the English course. This course is shared with other INSA students. For all students, a foreign language course is possible as optional course (German, Arabic, Chinese, German, Italian, Japanese, Portuguese, Russian, Spanish). Students who already started learning a language in their previous studies can thus continue their training, if technically possible (time table)
