Dogs Barking Advice Wanted

Does anyone have advice as how to handle lots of dogs barking during the day?

I live in an apartment where we can have pets, but lately it seems to be getting out of hand.

Most of the owners are not home I've noticed.

I'm thinking one dog can get the others all started?

Maybe they are excited about a new arrival? Last night just one was barking in the morning hours. However, I noticed today it's really quit.

Thanks for any tips and advice.
