Hi! I am a hearing aid and I am bored out of my mind.
It took years, no decades, for me to hone the skills to be a discriminating listener. At first, I could tell when sound was coming from the front versus other directions. Then, I could tell when you were speaking from when the fan was whirring or traffic was zipping by.
It took a lot of hard work but I even learned how to pull out the voice of whomever was speaking with you from the random noises in the background.
