Im asking these because when you mention the crack, pfft, whomp sound of each type of suppressor that leads me to think that frequency should be more of a driving factor in how a suppressor is design with overall loudness being next or Atleast equal. From what it seems like you’ve noted, the whomp sound could have a higher decibel measurement (overall louder) than the crack sound but because of the frequency it’s less harmful, noticeable, etc..
“The human ear's sensitivity to different frequencies is not equal, with the most sensitive range being between 2 kHz and 5 kHz. This means that the subjective loudness of a sound is not solely determined by its sound pressure level but also by other complex factors. Furthermore, this difference in frequency sensitivity is more pronounced at low sound pressure levels than at high ones. The equal loudness contours in the figure show the sound pressure level required at any frequency to give the same apparent loudness as a 1 kHz tone. For instance, a 50 Hz tone must be 15 dB higher than a l khz tone at a level of 70 dB to have the same subjective loudness.”
This is from Svantek’s website. Just got me curious if the frequency is taken into account - how much, should it be more or is there even enough of a frequency change that could make a difference?
