Your neighbor has other plans. Ten o'clock is precisely the time when he's fired up. As you alternately stew and fantasize about locking your noisy neighbor in a closet next to a boom box playing Barry Manilow's greatest hits on perpetual auto reverse, your stress level rises. Sleep is long forgotten. You arrive at work the next morning a complete zombie.
Some people seem to fear confrontation worse than death.
If you're consistently being disturbed by a noisy neighbor, the first step you should take is to obtain a copy of your city's noise ordinance. With a copy of your city's noise ordinance in hand, you can approach your landlord first and state your case, basing your argument on the terms outlined in the ordinance. Your landlord is legally required to adhere to the terms of your city's noise ordinance. If the landlord fails to address the issue with your neighbor and the problem continues, speak to your other neighbors, and find out if they've been bothered by the noise. If they've been kept awake or disturbed by the noise, ask those neighbors to approach the landlord, too.
