I am deaf with a cochlear implant, currently employed as a software developer.
You do not mention which country you're from - this answer is from a UK perspective.
As other answers have already mentioned, prospective employers are generally obligated to not discriminate against you because of your hearing impairment. This is enshrined in UK law in the Equality Act 2010, particularly section 6 and 21.
However, as you've already noticed, there is nothing to stop an employer deciding that making any reasonable adjustments is too much effort and ghosting you. This is illegal in the UK but unfortunately from my experience there is very little you can do about it, unless they make a big mistake like telling you 'why' they are no longer prepared to accept you as a candidate (Preferably in writing)
So my advice in this situation would have to be, say nothing about your hearing impairment until the interview. This prevents the employer writing you off as someone who would automatically need a BSL interpreter. (or any of a dozen assumptions that could be made...)
Remember that candidate onboarding isn't a solo activity. The people rejecting your cv offhand won't be the interviewers, it'll be someone in HR doing the initial shortlisting who thinks 'disability - potential liability - reject without a reason'
Having this conversation instead with the interviewer (Who is far more likely to be the role's actual supervisor) proved much more productive, at least in my experience. You can directly demonstrate to the employer your ability to communicate and how little effort would be required to make the necessary reasonable adjustments.
With regards to pre-main interview 'phone interviews', a company that won't make such a basic adjustment will make no adjustments elsewhere. In these cases, they have failed you. Try elsewhere.
Personal anecdote: When I was first job-hunting, my experiences were identical to yours. I made every effort to be as up-front about my hearing impairment and to summarize the minimum reasonable adjustments I would require to perform the job role. I got very few responses, which were ALL along of lines of 'sorry we do not think you're a fit for the company'
I changed tactics, deciding to tell prospective employers nothing about my hearing impairment until the interviews, which I suddenly started getting. One company made a formal offer, which they rescinded after the interview when someone 'higher up the chain' raised concerns about the reasonable adjustments. They were silly enough to declare this (and why) in an email so I ended up getting a reasonable settlement at the tribunal.
It literally took years after that to find my current employment but they couldn't be more accommodating. All communications is text-based except for mandatory client meetings (For which they changed the service used to one with automated captions - Microsoft Teams)
Best of luck finding an employer prepared to make the same effort for you.
