Calculate the noise contribution for each path and generate a vibration-acoustic model that reproduces the transmission of noise/vibration.
The "APR 620 TPA Project" is a fast and easy solution for building a transfer path model and analyzing the characteristics of sound sources and path contributions in the time domain. It enables the evaluation of the vibrational acoustic characteristics of measurement objects through transfer path synthesis. For measurements, TPA Data Acquisition (APR 610 required) and Recorder (APR 040 required) can be used. 【Supported Methods】 ■ Indirect input identification using inverse matrix (IFD) ■ Effective mount transfer function (EMTF) ■ Air propagation attenuation identification (p2p) ■ Indirect volume velocity (Q) identification (IQD) *For more details, please refer to the PDF materials or feel free to contact us.
