@Calvin5040 We have had violent cartoons for 80+ years. The problem is the Internet and all of this inter connectivity we have today where one click and your child just saw a porno or ISIS/Al Qaeda sawing off someones head or hands. The Internet is really an evil thing and I knew where it was headed even back in 1996 when people started to get it on dial up. By the time broadband came the writing was on the wall but then to put the icing on the shit cake parents are giving mobile devices to 7+ year olds. You do realize that the children of the founders of Tech are not allowed to have the Mobile Internet until they are 17, right? There is a reason for that.

@ZacharySalman5 жыл бұрын
I take issue with his comparison of nice and "yucky" sounds. The explanation of a siren chopping air into little pieces was completely correct and a perfect explanation in itself of how a siren works. However, the "yucky" part is both irrelevant and incorrect. First of all, a siren's rotor openings are evenly spaced, not irregularly spaced. Secondly, the siren speeding up does not make the sound yuckier or distort the sound waves in any way. It's just the same sound sweeping upwards in frequency. A siren may sound "yucky" due to the way its housing funnels the air, the presence of dual rotors, or other physical factors. However, most single-rotor sirens (especially Sentry's models in my opinion) sound generally pretty clear and un-"yucky."
@dforbesjr992 жыл бұрын
The explanation does make sense. The holes the air is being pushed through are constantly changing size due to the rotation of the fan. Compared to the nice sounds where the holes are of constant size
@ZacharySalman2 жыл бұрын
@@dforbesjr99 No, the changing size of the holes doesn't have any relevance to the "yuckiness" he was previously referring to, and he was wrong to imply that it did. The same hole size change was occurring with the "nice" sounding holes. The "yuckiness" he was referring to is an uneven placement of the holes, causing the pulses of air to be irregularly timed. The demonstration with the saw makes some sense as the sound frequency is actually being modulated irregularly because the holes are spaced unevenly around the disk, but when he demonstrates with the real siren, it disproves his point, because the holes in it are evenly spaced. The real siren he uses is actually the same thing as the "nice" sound on the saw. The only thing happening with the siren is the pitch increasing, there isn't any of the "yucky" as he described it earlier. "The faster it spins the yuckier it gets" doesn't make sense because, again, the only thing changing is the pitch, while the frequency, though increasing, is still even and regular.
