Why can we hear sound around us no matter what direction we are facing, but in order to see anything, we have to be facing in the direction of that object?

Question

Like I get that we obviously have ears on both sides of our head, but I would think that something that is directly ahead of us we should be unable to hear, since that object is basically perpendicular to our ears, but of course we can hear it absolutely fine. Why is that?

Answer 1

Because sound wraps around objects including your head. Light in the visual range doesn’t. There are energy levels or frequencies of light that can like radio but we can’t see those.
