Is it good to separate the pair of lovebirds?

This situation arises with my friend. One of the lovebird always shouting like anything to call the birds outside from his home. The other lovebird that is silent started to shout once the other one shout. He tried to separate these two by giving one to his friend. Do you think this will solve this lovebirds care problem? I don't think so!

I feel its much better to keep them together. I asked him whether he tried any alternatives? I adviced him to change the cage position as well as rearranging furniture so to act as sound barriers.

The major reason for the birds are louder are as follows-

1. when they may be bored. So give them new toys, things to destroy, chew on etc.

2. Go outside and see how loud they really are. Ask neighbors also...

3. Try to get a new home.

It is not at all advisable to separate them. Separation will definitely worsen the situation as the remaining bird will call for it's mate.
