I was wondering if deaf people commonly watch movies or TV with the sound on to feel the sound/music? Or is there not a sense of enjoyment if it can't be heard?
Pretty sure that depends entirely on the individual. Since being deaf (or blind for that matter) isn't as binary as it appears there are various degrees of hearing impairment. Perhaps one person is completely deaf, while another is still able to perceive certain frequencies, and yet another just needs it to be really fucking loud but if it is they hear just fine.
From my personal experience with a nearly deaf acquaintance they are using a special kind of hearing aid they can tie into their devices via Bluetooth. So they have the sound sent directly to the device specifically configured to allow them to hear.
You can be legally deaf and still able to hear sound that’s really loud. Just like you can be legally blind but able to make out really vivid and bright images.
Yep. I went to school with someone who was legally blind, though she had a large device with a camera and CRT screen to blow up the text so she could make it out.
