Do the writers think we're idiots?

Everybody knows that walking barefoot is quite noisy. The process of putting down and removing bare feet from the floor creates a distinct sound. Especially on wooden floors, where it's next to impossible to be quiet when barefoot. So why have the characters walking around barefoot on wooden floors? A certain suspension of disbelief is always to be expected in any film, but do the writers seriously expect us to pretend that we aren't aware that bare feet makes a sound?

Because you know what makes much less noise than walking barefoot? WEARING SOCKS! Furry slippers or even sneakers will also make much less noise when touching the ground. So why not have all the characters wearing thick socks? Heck, they should probably be wearing triple pairs of socks, just to be extra protected!

Also: Why the hell have the characters live in a wooden house, filled with stuff that can fall onto the floor at any moment? There's even a scene where the mother straightens a picture hanging on the friggin wall! WHY?

If they really wanted to make us believe the premise, then the first thing any sane person would do, would be to move into a building with thick concrete walls, and then put PADDING ON EVERYTHING! There should have been thick carpets and pillows fastened to the walls. Every fork and plate and screwdriver would have a thick layer of tape around it, to dampen any sound should it fall to the ground. And every goddamn picture would be taken down from the walls!

Additionally: Why the hell didn't they set up a few noise-makers around the place? If these monsters only go after sound, it would be super easy to distract them, by putting up a bunch of decoys around the house. For example, you could place a few cans out in the yard and tie them up with a string that you could pull from within the house at any time.

I mean... COME ON!
