What do you fly? Most of the pilots here use noise canceling headphones. I tried someone’s pair and didn’t think that they did much of anything.

When I took the reading of 114 dB I was just aft of the landing gear with a line of sight to all for engines. Actually at or just above ground idle these things aren’t really that loud compared to something like an F4 or AV8B. However, when we do engine trims and take them up to TRT the ground shakes and it’s deafening a couple hundred meters away. I keep forgetting to take my meter in for a power run hopefully I’ll remember next time.
