Automotive Steering Acoustic Test Room
A semi anechoic test room for automotive steering systems, combining absorptive walls with a floor isolated from vibration for component noise and buzz squeak rattle testing.
Project Highlights
- Semi anechoic free field design
- Base isolated from vibration to suppress structure noise
- Compatible with test rigs and in line testing
The minor noise and rattle produced by a steering system during operation bear directly on the perceived quality of the entire vehicle. Anteck constructed a semi anechoic test room for the customer, with absorptive modules applied to the walls and ceiling to establish free field conditions, while the floor retains a reflective surface to accommodate the test rig and the assembly under test.
A base isolated from vibration together with acoustic doors and windows reduces external vibration and noise to a very low level, enabling engineers to clearly distinguish the motor noise, the gear mesh and any structural rattle within the steering mechanism, and subsequently perform both objective measurement and subjective evaluation.
