Q-MED is a low frequency monopole source designed to measure vibro-acoustic transfer functions in and around vehicles.
The negligible diffraction makes it an accurate omnidirectional sound source up to 2,000 Hz. allowing typical vibroacoustic body noise transfer functions measurements including frequency response functions (FRFs).
A recent Siemens Simcenter blogpost provides a step by step approach to obtaining the most accurate results using corrected values for analysis and comparison to avoid influence of the source on the measured FRF.
This article explains how to use the data from the Q-MED calibration report as well as post processing calculations to account for variations of source sensitivity and applying corrections in amplitude.
