Targeted noise control for quieter and lighter structures
A cutting-edge approach to pinpoint and mitigate noise from vibrating structures by identifying and addressing local deficiencies in stiffness, damping, and mass, making structures quieter and lighter.
Overview
Targeted noise control is a revolutionary methodology designed to pinpoint and mitigate noise sources in vibrating structures. By identifying local deficiencies in stiffness, damping, and mass, this approach allows for precise modifications that make structures both quieter and lighter. The core hypothesis is that only certain structural vibrations contribute to sound radiation, and by addressing these specific components, effective noise reduction can be achieved without unnecessary alterations.
Technical specifications
Key features:
- Identifies components of structural vibrations that support sound radiation
- Enables targeted modifications to stiffness, damping, and mass
- Utilizes acoustic and vibration signal measurements for precise analysis
- Supports virtual design and modification through CAD modeling
- Provides optimal strategies for noise emission reduction
Technology readiness level
This methodology is at Technology Readiness Level 9, indicating that it has been fully validated and is ready for commercial application. It offers users the ability to perform both in-situ measurements and virtual design modifications to achieve desired noise reduction outcomes.
