Someone else out there understands what it means to have noisy neighbors.  They made a CD you can play that has annoying sounds on it. It comes with earplugs so that you don’t get bombarded with your own stuff. 

As fun as it may sound, if your neighbors are that noisy, it’s unlikely they’ll hear whatever noise you throw their direction.  Either from the hearing loss or over their noise, this may just frustrate more.  But it may be worth that one time you get on their nerves. 😉
