ambience makes a huge difference. just the sounds of the scenes kept me interested in listening through all 8 seasons of game of thrones. the crackling fire of a torch inside an underground cavern, the clanging of swords during an intensive battle, all these things make the story way more immersive and worth sticking through. i would much rather hear the sounds of a scene instead of someone just reading the story to me. it also helps a lot with describing a scene without having to say it, such as a thunderstorm masking loud noises or wading through a river. you get more information conveyed to you this way and it's done so in less words.

Great job imo. I can only speak for myself but I liked it.

Blind people absolutely do watch/listen to TV. 

As Somebody Who is both visually impaired, and a writer, composer, sound designer and voice actor with a special interest in creating audio dramas, I can say yes, I think many, many cited and blind people would agree that audio storytelling is vastly enhanced by sound effects, music and voice acting. Do not get me wrong, there’s absolutely nothing wrong with a good old-fashioned audiobook. But Audio drama is extremely immersive, and if the audio drama sub Reddit is any indication, it’s receiving a huge resurgence in popularity.

Personally, I like for there to be no sound effects when listening to an audiobook, creepy pasta or someone reading something in general. This helps me to focus my attention to the story alone with no distractions. constant quiet music is an exception to the fact, I generally prefer creepy pastas with music, and audiobooks without.
However, I don't mind in the slightest with other things like Youtube videos, movies, anime and everything else. The only times it matters to me are: when listening to an audiobook, Reading or creepy pasta.
