Failing newborn hearing test

So I’m

Curious if anyone else’s LO failed the newborn hearing test in the hospital? My 7 week old was referred.

She sees a specialist next week.

However since she’s been home , I noticed she hears everything ! She gets startled from the A/c turning on, a door opening , dishes being put away. I play music and she smiles. If she’s sleeping , every little sound startles her. so I don’t know. I’m confused 😐
