I live in a developing country where noise laws are virtually nonexistent or never enforced. If your neighbor decides to play music at full volume during the "permitted" hours, smash everything, and scream loudly every day from 7 a.m. to 10 p.m., there's nothing you can do. The police won't come, and if they do, they'll simply say, "It's their apartment, they can do whatever they want."
Can you protect yourself if your neighbor makes a lot of noise during the day, during the permitted hours, but does so without interruption?
What penalties are provided for noisy neighbors?
Is it difficult to protect your rights in such cases?
