Quiet Enjoyment has nothing to do with noise. Quiet enjoyment means the landlord will not take action to remove you from possession. If you're on a month to month tenancy, give your notice and move in thirty days. If you're on a lease (I wonder why) you're in a position where you'll have to convince the landlord that it would be in their best interest to release you from that lease.
A proper response would require a thorough investigation into the history and background of this relationship. The information provided above is just that, information, to be used as you see fit.
Talk to your landlord and attempt to get out of your lease early.
