Help, about the sound effect!

Hi All!
This is the problem I have. If I hit an enemy and make a hit sound, it’s normal. But if I hit two enemies at the same time, then I will play the same sound effect of two attacks at the same time, and the sound will become very loud. If more enemies are hit at the same time, the sound will be louder. How to solve this problem?

Sound Concurrency.

Thank you very much. I will go to study!
