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.
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.
