Hi-decibel employee

[angelove]

We have a summer intern who is incredibly loud - I can hear him fifty yards away. Whether he's on the phone or talking to someone in person, the volume is always turned all the way up. I'm not hypersensitive - everyone else is annoyed by him, and he's affecting the work of others in the office. We have actual walled offices too, not cubicles, so his voice carries through the walls. It's highly unlikely that he's going to be offered a permanent position anyway, so should I say something to him about the volume? If so, any suggestions on how to do it tactfully?

ETA: This has been an ongoing problem since June, and "Could you please keep it down? I'm in the middle of a big project" works only temporarily. It's time for drastic measures ...
