Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Aim

The course intends to give an in-depth knowledge about structure- borne sound and its control. The course focuses on the prediction and control of sound propagation in structures and the radiation of sound from structures. The course is recommended for those students who intend to focus on noise control engineering. It is highly advised that students continue with Technical acoustics 2, where the subjects of Technical acoustics 1 are practiced on a real-life example.

Goal

The student will learn the basics of structure-borne sound. This includes:
· The damping in structures and appropriate models to describe damping;
· The main waves in structures, their properties and their description;
· The control of structure-borne sound;
· The basics of sound radiation from vibrating structures.

Content

The course comprises the following elements:
- Discrete (lumped) dynamic systems.
- The vibration field and wave types in solids, beams and plates.
- Vibrating finite systems.
- Mobility description
- Modal description of vibrational fields.
- Inluence of impedance variation -blocking mass, elastic interlayer
- Damping mechanisms - damping models
- Damping layers
- Statistical Energy Analysis
- Basic radiators, radiation from vibrating surfaces.
- Integral equations, BE-calculations. Radiation factors.

Organisation

Lectures and excercises
Included in the course is an engineering exercise.
