yes it's going to be awesome for hearing impaired party-people to use this stuff... it's also going to be a blast for everyone else.
the inclusivity will be that as a hearing-impaired person you are experiencing a good chunk of the SAME experience that hearing-enabled folks are experiencing at the same time, because yeah... hearing people are greedy for sensory fun beyond hearing as well
and don't forget vision impaired people as well... a great party will have sound, lights and physical sense now... and almost everyone will be able to experience at least two of those, so almost everyone gets most of the experience (even deaf-blind folks can enjoy the physical third so there is literally something for everyone)
And not to be glib, but if you are deaf, blind, and have been badly burned so your nerves don't work, you've got bigger problems than party issues.
