Yes they do loosen a little, just enough to allow the braces to shift slightly. It is a very common problem. The sound you're hearing is transferring from the strut tower braces to the firewall that they are attached to. There's a round cover just rearward of the microfilter that contains one of the bolts you need to tighten. It's a big e-torx.
