Analyze noise transfer characteristic
Analyze noise transfer characteristic using TPA
In order to reduce noise in vehicles, the path of noise needs to be determined.
In general, there are two types of detectable noise: Structure-born and Air-born noise.
Both of these noise can be classified and find the path contribution by utilizing the TPA technique.
The goals of TPA are evaluating the contribution of the energy paths between the sources and the receiver, and optimizing the design by setting desirable characteristics for the corresponding paths.
