Noise coming from the screen of the iPhone XR?

My iPhone XR screen got hit a bit hard by my arm last week by mistake. On the same day of this incident, the screen made a weird loud noise when I swiped up but the problem is that I am not sure if it is the screen or not. But thankfully this noise happened once only. A day after, I became a bit worried if I caused any damage so I began observing the phone. I realized that sometimes the screen makes a noise when I touch it. Sometimes the screen won't make any noises and is completely fine. The noise is different every time, sometimes it's like a clicking noise.

Could it be from my screen protector? Or is it hardware damage? My screen protector is a bit thick so I am not sure if it coming from that screen protector.
