This is realistic and varied surf waves, so it might keep you up.
Sleeping with the TV on works sometimes too.
Eat a couple of fattening buttery cookies (like Danish butter cookies) and a glass of warm milk about a half hour before you need to go to sleep. It diverts the blood from the brain (not all of it of course) to digest the fat and helps you sleep as it takes you mind off things. Do set your alarm cause your body clock might not work as expected.
Plan on moving and find out when they sleep. When your about a week before leaving, reply in kind.
A small constantly barking dog really annoys the neighbors to no avail, better yet, a rooster.
Oh sweet jesus! Come back a few weeks later and let a few roosters and chickens loose in the yard near a big shady tree, leave out some rice or corn and water so they stick around.
Watch the fireworks!! LOL!!!
Since you in the upstairs apartment, your likely causing a lot of noise unknowingly just by walking around and then asking your neighbors to be quiet. They think your crazy likely.
1: Take off your shoes when you enter, guests too. Walk on your toes, not your heels, makes a huge difference.
2: Use carpet with padding
3: Use one of those sweeper pad things instead of a vacuum cleaner on wood floors
4: Avoid rolling or floor banging objects like chairs and such
5: When they are home, be extra cat like quiet, use headphones for your stereo needs
6: Monitor your noise level with a meter so you can get a idea what sound levels travel through the walls and floors.
7: Make so little noise and be unseen by your neighbors that they think you went on vacation or something
Tell your neighbors you are trying to ultra quiet and ask them if they would keep the noise level down after a certain time, like 9 PM or something. It will shock them that you have been there all the time and they may respect your request in kind.
If not, then well, get the roosters... and a tiny barking dog....
