Fighting man audibly the worse for shouting? (5,7)

'audibly the worse for shouting?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'fighting man' is the wordplay.
I cannot really see how this works, but
'man' could be 'soldier' (soldier is a kind of man) and 'soldier' is found within the answer.
The remaining letters 'horse' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
