adjusting the sound for the hearing impaired is flawed with the HomePod mini
I have a significant hearing loss of 45% in both ears. The HomePod accessibility settings make it so that the volume with go louder based off how loud you speak and its environment but that isn't sufficient. Can you imagine someone with a hearing loss have to scream every question or request to there HomePod so they can hear the response. I'm sure that makes a funny picture in your head, mine too. Try living it every day...... So I think it would be best to have Siri have a separate volume control then the media like you do with CarPlay. Just saying.
