Hello, I'm contemplating building a DIY overflow detailed on this site. I had a few questions regarding the style of overflow. I'm considering these two designs:

First, my main concern is sound, as this will be in my bedroom. Which of the two will be the quietest?
Secondly, it seems that the design of the second link is more like a true overflow design, with the input of water into the sump is coupled with the amount of water the pump is putting back into the main tank. While the overflow in the first link has its own inherent flow rate (based on the diameter, etc.) since it is a siphon. Therefore, I will need to adjust either the overflow rate or the pump's rate to match the two. Are these observations correct?
Lastly, the noise of the overflow (the gurgling) is air being sucked int othe siphon, correct? This will happen either at the intake and/or where the vent tube meets the tee, where it again sucks air in. To minimize this, can I just use multiple overflows with lowered flow rate in each to prevent air from being sucked in? What about expanding the diameter of the piping AFTER the tee to prevent a siphon from building?
Sorry, the post was longer than I was expecting. Thanks for your insight and response!
