Simcenter Qsources low-mid frequency source

Simcenter low-mid frequency source unit is placed on a car seat.
The Simcenter Qsources hardware low-mid frequency source is used for producing high noise levels, more than sufficient for the excitation of complete vehicles. The integrated volume acceleration sensor gives real-time feedback of the emitted source strength and can be used as a reference for frequency response functions (FRFs) measurements without any postprocessing.

Since 1996 almost all automotive manufacturers and many suppliers have used these sources for improving the acoustic performance of their products on the system level. The low-mid frequency source is designed to be used in the 10 to 1,000 hertz (Hz) frequency band an important frequency band in vehicle development. This source is typically used for transfer path analysis (TPA) of structure-borne or airborne noise and cabin vibro-acoustic modal analysis.
