Reaching your ear is the sound of a drunkard who can’t find employment. You hear him before you see him because he’s behind some trash cans. Being a drunkard, he’s like, super wasted and just kind of rambling to himself, making strange sounds. No wonder he can’t find employment.
Since this guy is such a pathetic drunkard, it comes as no shock (しょく) that he can’t find employment. If he did find employment, I would be filled with both shock and awe.
