Transfer Path Analysis (TPA) is a technique used to break down a noise or vibration problem into its key contributors. These contributors are identified using source loads and transfer functions to the response at a target location.
To understand the response at the target, the following are used:
- Source: Characterized by forces, the source creates the input loads into the system.
- Transfer: Transfer functions (Frequency Response Functions) characterize how noise and vibration is transferred from the source to the target location.
- Target: Location where an unwanted vibration or noise is perceived. The examples in this article use sound pressure at a target location, but the technique is equally applicable to vibration.
Transfer Path Analysis can be used with physical measurements, simulation data, or a combination of the two.
