You can report the loud noise complaint to the Fort Wayne Police Department using the non-emergency line anytme; the number is 427-1222. Check out the city ordinance: 96.03 LOUD AND UNNECESSARY NOISE PROHIBITED http://bit.ly/fgOhBU
It is really smart of you to recognize that these will be your neighbors for some time, and that perhaps a more subtle approach would be appropriate. Since you are asking, I would encourage you to connect with the head of your neighborhood association before making that call to the FWPD. But if the noise level does not decrease after that, then yes, contact the department and request that the ordinance be enforced.
