Product testing is a critical element in the development of solutions to noise and vibration issues. Roush provides diverse noise and vibration testing services to quantify and characterize the sources and paths responsible for product noise and vibration.
Testing and data processing capabilities include:
Noise Testing
- Sound pressure, intensity and power
- Binaural measurements and sound quality
- Acoustic Holography
- Structural-acoustic coupling
- Ultrasonic leak (acoustic seals)
- Subjective evaluation
- Vehicle passby noise
Vibration Testing
- Frequency response and modal analysis
- Operating deflection shape
- Component durability
- Strain gauge
- Torsional vibration
- Subjective evaluation
Miscellaneous Testing
Advanced Data Processing
- Noise path analysis (NPA)
- Multi-input/Multi-output (MIMO)
- Time/frequency analysis
- Order tracking
- GABRIEL
Testing Facilities
- Automotive vehicle NVH chassis roll dynamometer
- Hemi-anechoic chambers for product testing
- Hemi-anechoic chambers with engine/transmission dynamometers
- Ultra-low noise floor for operation of quiet equipment (e.g., disk drive, computer, etc.)
- Brake noise dynamometer
