Testing and measurement techniques for accurate acoustic system analysis
The objective of acoustic measurement and testing techniques is, of course, to arrive at an understanding of the acoustic system as a basis for determining specific problem-solving and optimisation activities.
We perform measurements both in the laboratory and on operational machinery, plant and equipment, recording the full range of internal and external noise, both steady-state and transitory. The data thus acquired enable identification of relevant excitation sources, transmission paths and emission locations.
- Sound pressure measurements with acoustic camera
- Sound pressure and intensity measurements
- Structure-borne and fluid-borne sound measurements
- Transfer path analyses
- Experimental modal analyses
Acoustic optimisation based on simulation techniques
We utilise vibroacoustics simulation in the development of quiet machines and vehicles.
- Modal analyses (Matrix Structural Analysis, FEM, MBS)
- Frequency response analyses (FEM, MBS)
- Calculation of the radiated sound field (Boundary Element Method)
- Noise forecasts
Mastery of these techniques enables us to support – even during the early development phase – the client’s concept and layout definition work or the selection and design of e.g. acoustic hoods, screens, silencers and insulation systems. As a result, development time and cost can be appreciably reduced.
Single-source acoustic solutions
If required, we can also offer the engineering, design, manufacture and supply of tailored solutions for noise reduction, with offerings such as:
- Complete noise kits
- Acoustic hoods, enclosures and screens
- Silencers, mufflers and sound absorbers
- Sound-insulated cabins
