Re: distorted sounds & sensitivity post stapedectomy
I'm at 32 days, had the same symptoms as you. It's improving in small incremental doses.
After you get your packing taken out ask your surg about wearing an ear plug when around noisies (and not now before the packing is out!). I have and that's helped. However you being only 13 days out now i think you should avoid stuff like the volleyball game completely until you can make it to ear plug stage. I had the same experience walking thru a casino to the buffet. The slot machines sounded like come-to-life-Transformers-Movie-Monsters attacking me!
House of Hearing in LA says that 3-6 weeks is normal recovery and 4 months is possible.
