This cold has been causing noticeable high-frequency deafness. My hearing is normally excellent for my age across all frequencies; I do have trouble (and have had all my life) picking out conversation from background noise, but that isn't a hearing problem, that's a brain processing problem. I keep my headphones permanently plugged into the laptop, so if it beeps (as it does when I get a Mastodon or Discord notification), the beep will come through the headphones and therefore be extremely quiet. Normally I can hear that from the kitchen; at the moment I can't hear it at all, so I have to rely on the visual cues if I am sitting in front of the laptop. Since that doesn't necessarily imply that I'm looking at the screen (I may be doing crafts or scribal work), I'm currently missing a lot of them.
And then there's the air fryer. On Friday I made banana loaf, and I slightly goofed about the cooking time (each loaf takes 40 minutes, rather than the 30 I had in my head), so the air fryer was still going when I put my headphones on to wait for my sister to show up on the regular Friday evening Zoom call. I could hear that just fine, headphones notwithstanding, as it is a low-frequency purr. I could also, naturally, hear when it stopped. But I couldn't hear the beep at all, and that startled me; I'd normally take that for granted.
Yesterday morning I ran the washing machine, which has a much quieter beep. I wasn't wearing the headphones. I couldn't hear that, either.
So I went here: https://sound-tester.com/frequency-test I then tested my hearing range, and found I couldn't hear anything above about 9 kHz. In the process, I discovered that quite a lot of people over 40 can't either, cold or no cold. I'm over 60. Even so, I know what I'm used to being able to hear!
This morning I tested again. I'm now topping out at about 9.3 kHz, which is a significant overnight improvement, and it tells me I'm finally on the mend. About time, too, because I've had the dratted cold for more than a week now. I look forward to finding out what the top of my hearing range normally is!
