It apparently is poorly defined:
A paracusia, or auditory hallucination,[1] is a form of hallucination that involves perceiving sounds without auditory stimulus.

I would not consider what the woman in the article describes to be an auditory hallucination. She knows it isn't real. She doesn't perceive it to be actual sound. Yet, the Wikipedia article also talks about hearing voices as a form of auditory hallucination.
I have had actual auditory hallucinations a few times. The first time it was a medication side effect. I had taken too much decongestant and I would close my eyes and hear things, like people in the room with me opening drawers or something. When I opened my eyes, they were not there. So it was not real.
This has happened a few other times when I was basically very sick and stressed out. I once heard steps when no one was there. It was a bit like radio sound effect steps. It was disconnected from what it would have sounded like had someone actually been walking nearby and it neither approached nor receded, which is part of how I knew it wasn't real. I once heard someone say "Hello" and figured out this was not real, there was no one there.
Since I now know this happens occasionally, if I hear things that seem off in some way, I can check for corroborating evidence to see if it is real or not. It is very uncommon. I think it has happened like 3 to 5 times in the past 6 years. But if I am very sick, wonky things go on in my mind sometimes and I have learned to check on certain things.
I was homeless for several years. I camped in an area for 2+ years with a lot of birds. Birds, especially geese, can sound like indistinct human voices, especially a woman's voice. So during that time I regularly had to determine if actual real world sounds were human voices or bird voices because humans near my campsite were a potential threat to me. Birds were not.
That experience where I was literally hearing things, but struggling to determine exactly what the sound signified, helped make me feel comfortable double checking when I hear things and am not sure if it is real or not. If I know I am sick and under duress and what I think I hear seems off in some way, I just try to verify if it is something real or not.
