Of course YMMV. Having spent two spells recently in hospital after surgery, it didn’t bother me in the slightest being woken for 30s every few hours. Usually it coincided with me being brought painkillers, water and snacks. All of which were welcome. There was also no issue regarding beeps in the post operative care unit that I remember. I was also given my personal belongings, as soon as I was able to structure a coherent sentence, which included headphones. Similarly to other commenters, I should point out you might not be so quick to use technology to solve this problem. Implementing technology into an area where lives are at risk (ICU) takes a long time - with good reason. I saw a comment talking about a centralised monitoring desk. Good luck finding a ward where you are always staffed enough to have someone watching that. There is a good reason sounds have remained as the primary monitoring cue for so many years.
