Unfortunately, there is a significant error in this article.
"Kleenex did not absorb any high frequencies when placed over the microphone capsule, while Figures 15 thru 18 indicate that the HF attenuation affect of tissue is position dependent. ...
... The paper filters are not absorbing the high frequencies, but simply reflecting them back into the tweeter, thereby causing cancellation through comb filtering."
This conclusion is ignoring the fact that attenuation by porous materials is directly dependant on particle speed. It is well known since long that attenuation by fibrous or porous materials is most efficient when placed close to the source.
Makes a difference when I fart, for sure. :-[leadbreath said:Yes but does it feel any better when you wipe your bum with it....? Now that is the question ;D
