I think it will always require some adaptation to your needs, software development pretty much will always have at least online meetings where you talk about progress on tasks and plan which tasks each person will be working on. It wouldn't be hard to adapt it for a person who can't hear, in my opinion, but depends on the team's willingness anyway. There's already some AI tools that record meetings and can give you scripts of what was said, who said what etc. So that might be even less of an issue now.

Regardless, the hardest part would be the learning the skills and getting the first job, I'd say try it out, and if you completely get obsessed about it, go for it, it can be so fulfilling and addictive. If you end up not enjoying that much but want to do it for the money nonetheless, maybe scour through reddit to see how tough the job market is for junior developers, and that might make you rethink if you really want to invest countless hours on it and risk in the end not even being able to get a job and hating the process the whole way through. I've converted two years ago, in a period where jobs were already scarce and where less and less juniors are being hired, but I was extremely lucky. But also, I was completely hooked to it, I didn't care if I couldn't switch careers right away because all I wanted to do on my free time was programming anyway, so I was happy to slave away all the hours needed to self teach.

Good luck!
