Pass-by Source Path Contribution

BK Connect® Pass-by SPC helps you investigate the contribution of noise sources such as tyres, engine/motor, exhaust, to the overall pass-by noise.

Source Path Contribution (SPC) analysis is a technique for evaluating noise contributions from suspected sound or vibration sources through various acoustic or vibroacoustic paths to a desired receiver location. Dominant sources with respect to a given receiver can be highlighted to help focus engineering effort where it has the greatest effect. While SPC methods are often used for interior cabin noise analysis with sources and paths being both acoustic and vibratory, BK Connect Pass-by SPC is specially designed for pure acoustic analysis using measurements from an indoor pass-by setup. 

Unlike some other solutions, BK Connect’s SPC methods calculate source contributions explicitly, rather than breaking down the measured total sound into contributions. By comparing the sum of contributions with the original overall measured data, you get a true validation of the model with results that are obtained independently of each other. A close match gives confidence in the modelling assumptions, which is important when using SPC for making real engineering decisions such as in design optimization or problem resolution.
