Is it normal to have difficulty concentrating on visual intake?

Here how it goes.
I find it difficult to concentrate on what I'm seeing if my attention is catch,more like hijacked,by somebody talking or weird unusual sounds nearby that shouldn't be there?And to feel very anxious about those sounds?To the point of wanting to run away or find the source of the unusual sounds to kill it?It also happens with other sensorial input.Such as tactile stimulation.
And I end up being disoriented and disorganized because my attention is constantly attracted to those sounds. Which I know are there because I can tell the difference between a real sound and music running in my head.
