We use the resulting parameters of the two different model decompositions of mid-infrared (MIR) spectra of 1) active and star-forming galaxies and 2) active galactic nuclei (AGN). These resulting parameters are the AGN, polycyclic aromatic hydrocarbons – PAH, H II and stellar contribution components, silicate contribution, etc. It is found that some of these parameters correlate with X-ray hardness ratios (especially HR1). This reveals the insight in the X-ray energy bands that influence the MIR parameters and it can point to the AGN sources that are more obscured. These correlations indicate the high attenuation of soft X-ray radiation by the dust.
