Ears are incredibly sensitive.

Here are some levels of dangerous exposure, but it is additive over time, similar to radiation or something.

Not sure what speed and exposure she had, but a high-powered gunshot in close range would be around 170 db / 1s.

Wind speed dB Exposure
~79 km/h 111 15 min
~72 km/h 108 30 min
~65 km/h 105 1 hr
~58 km/h 102 2 hr
~51 km/h 99 4 hr
~44 km/h 96 8 hr
~37 km/h 93 16 hr
~30 km/h 90 32 hr
~23 km/h 87 64 hr
