Takes years to develop, and probably affects many who don't know, after all.... How can you know what you don't hear anymore?
Huh?
Say again?

Ok, back to topic!
What I have had many times is a short (5- 15 second) high-pitched sound in one or both ears. These are often accompanied with what felt like a pressure change in affected ears.
Many people have said to be able to associate these occurences with subsequent earthquakes. So far, I have not. The last one I had was around mid-October, about 8 pm one night.

I know what I don't hear, I have a whistling kettle and the sound just disappears for a bit when it gets really high
But I have also had the pressure change thing you mentioned and that has nothing to do with my hearing ability
