My experience is similar to Jacks2... Some deaf and near deaf girls moved into the then vacant home next door to me. I understand physical challenges all to well. I have more trouble with poor behavior however.
they all worked second shift and after working would crank up the subs as loud as they could get them. I've no problem with loud music usually, but at 2AM? Naturally on their days off party time seemed to keep similar hours. Additionally, the place they all worked at also hired many other hearing imparied folks... so they would routinely hold parties and continue well past midnight with thunderous booming subs shaking even the tables and seats in my home!
I asked numerous times for them to keep it to a quiet roar after midnight... all to no avail. Finally I had to call the police. Several times! They just didn't get the notion of neighborly consideration.
Ultimately they moved on... Peace and quiet again!
Until.... a bass player moved in two months ago! yeah... he plays it loud too... but not late at night, thank God.
The resolution?
Ear plugs.
