Do You Hear Sounds Not Heard or Heard Later By Others?

Sound sensitivity distracts Joe so much he becomes unaware that he has stopped walking and talking to his friend, Josh. Two friends, Joe and Josh are enjoying some time outside. Suddenly Joe stops talking and looks up. He hears the noise of an airplane flying overhead. His friend, Josh looks around hearing nothing but birds. Josh follows the gaze of his friend but sees nothing and says,"What do you see?". Joe replies, "Don't you hear the jet?" Josh looks and only sees a trail of white up in the sky.
