Yes, I do have that sometimes.
Sometimes, all of sudden it feels like I'm hearing things. Sometimes it's like a VROOOOM kind. Sometimes, it's banging.
Whenever it's banging, I try to make my own noises opposite of banging noises to see if I really can hear. Same for VROOOOM kind too. It seems like I was imagining several times. The last time I "heard" something was about a week ago. I haven't wore my Cochlear Implant for like 4 to 5 yrs.
