AirPods Pro 3 weird noise

I bought an AirPods Pro 3 recently, but I notice that when I'm walking in my apartment hallway, both earbuds will always make weird noises, no matter if it's in transparency or noise-cancelling mode, but when I walk outside or in my room, this never happens, is it because my AirPods is a defect? Or because this is a common issue everyone is experiencing
