Totally agree about shape making a difference. We switched to circular vents in our storm shelter last spring, and the airflow felt smoother almost immediately. Didn't expect much from such a small change, but it really did help...guess details matter more than we think sometimes.
Interesting observation—did you notice if the circular vents affected noise levels at all? I've found small shape changes can sometimes reduce echo or vibration too...curious if you experienced anything similar. Either way, nice job paying attention to those details.
I've messed around with vent shapes quite a bit in my own projects, and honestly, shape alone rarely makes a noticeable dent in noise or echo unless you're dealing with pretty specific acoustics. Usually, it's more about material and placement—like adding some insulation or soundproofing foam around the vents. Circular vents might look cleaner, sure, but if noise reduction is your goal, I'd put my money on strategic insulation every time. Just my two cents from trial and error...
"Usually, it's more about material and placement—like adding some insulation or soundproofing foam around the vents."
Totally agree on this. I've flipped a few houses with storm shelters, and insulation placement made way more difference than vent shape ever did. Circular vents might look sleek, but function beats form when it comes to noise control. Glad your shelter passed inspection smoothly—always a relief when that happens after putting in the work!

Yeah, insulation placement is key. I remember spending hours tweaking foam placement around vents in my basement remodel—made a huge difference compared to just swapping vent shapes. Glad your inspection went smoothly; that's always the best feeling after all that effort.
