A while back I asked my GP if there was anything that could be investigated regards my seemingly worsening hearing problems (while I've always had auditory processing problems, hyperacusis has grown over time and tinnitus was new to me)
She said she'd arrange a referral, and shortly afterwards I got a text with a link to a document that had a phone number for me to call to make a hearing test appointment. I say again:
a phone number for me to call to make a hearing test appointment
No other options, just the phone number. I tried Googling around it, and no, just the phone number and a street address.
I tried the phone number, and there was a lot of hold music—loud, Vivaldi (a lot of sudden up and down volumes and pitches, a real nightmare for me), interspersed with quiet moments in which in unclear voice would tell me how important it was, before hurting my ears with Vivaldi again. And I don't mean like "haha that music hurts my ears", I mean like, it hurts.
Eventually I gave up and figured I'd go to the physical place.
The receptionist had a mask and a speech impediment and there were fans whirring. Suffice it to say: the conversation was difficult.
Eventually I understood enough to understand: I could not make an appointment there, the only way was to call the phone number. To make a hearing test appointment.
Basically, the HoH equivalent of "if you need the key to the accessible toilet facilities, ask at the café upstairs"
