NVH ENGINEERING & TEST SERVICES
PRODUCT TESTING

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
. Moment of inertia

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
