Noisy Neighbours

Hi guys,

I'll keep this short. So my neighbour of 7 years, broke up with her fiancee and quickly moved on with another man. This is not the topic though. The new man spends so much time around my neighbour's house and he's lovely however he is incredibly loud. They got another dog together who doesn't stop barking and barks at 3/4/5am in the morning. She also has become very loud with loud banging at random times of the day, loud music and slamming of doors. Her other neighbour has a toddler and a young child so I feel more sorry for them.

AIBU in thinking that she should be respectful of her neighbours and keep the noise down?
