Whoa DAT slow down. First you diss the deaf for not havin phones then take a shot at the blind?? Who's next, the halt, lame, and crippled. 
Now I am one who has hearing loss (but with aids can hear), a back that goes out more than I do (but I know to limit what I do) , and can barely see with out my glasses (ok I can't drive without them even though they have Braille at some drive-thru's). The sad part of all this is that I am in better shape than most dummies heck I don't even rate one of those handicapped stickers they are so proud of.
And, I seem to be on the poll list for a couple organizations (Rasmussen was the last one to call and there is another here in NH who's name escapes me at the moment). Just why I do not know. How the calls go depend a lot on the phone I am on and the phone the caller is on. Usually a cheap cell phone call is impossible to hear, ditto fast talkers, low talkers and those with a pronounced accent (think Indian or Southern ).
Not at all, you're jumping to the unfounded conclusion that no deaf people have phones and everyone else does. That's not what I said at all.
Lots of houses where deaf people live have phones, because like anyone else, most of the deaf live with other people, and generally not just with other deaf people. At the same time, there area lot of normally-hearing people who don't have phones, especially landlines, and cell numbers are not as accessible for sampling. So, no phone means no call from the survey people, which is what I said.
If the caller does have a number, all they usually really know is that it's a phone number to a residence. They have no way of knowing if there is a deaf person at that number before they call.
Ergo, no phone, no call. It has exactly Jack Shit to do with whether some shit-for-brains deaf DUmmie lives where the phone is located.
