Delivering the Sound of Silence

Signalysis provides advanced engineering testing services for manufacturers who require accurate, repeatable, and scalable validation of structural integrity, dynamic performance, and functional quality. We combine decades of practical noise and vibration experience with proven experimental dynamics, automated data acquisition, and analytics methods to support both production and development environments.

Our Testing Services

Our test systems and engineering services are focused on structural dynamics, vibration analysis, and production validation. We design, develop, and deploy testing systems that measure dynamic response, modal behavior, and functional performance using vibration, acoustic, and resonance-based methods.

Non-Destructive Testing (NDT)

  • Resonance Testing (Dinger™ System): Detects cracks, voids, porosity, and inconsistencies across metal, ceramic, and fabricated components
  • Vibration Inspection: Identifies subtle material and assembly defects
  • Modal Parameter Analysis: Detects structural deviations and integrity loss
  • Impact and Response Testing: Evaluates FRFs and dynamic stiffness
  • Acoustic and Structural Evaluation: Identifies energy transmission changes

All methods are supported by high-resolution acquisition and SigQC™ analytics.
