Hi Alex. I read your “superpower” thread, but not any others from you, so you may have addressed this already. But what caused your sudden loss? It’s not normal for that to happen You should visit an ear doctor ASAP.
As far as playing music, I have a similar situation. I had an acoustic neuroma in my left ear a few years ago. It was treated with Gamma Knife, and am lucky to have retained some aidable hearing in that ear.
As the neuroma was developing I was playing in an amplified acoustic duo. My musical partner’s wedge monitor would blare into my left ear, and it gradually started to sound like an atonal roar. I lost my ability to discern pitch and my singing suffered greatly. I had to quit that act. The distortion continued after the Gamma Knife surgery.
Now anytime I play music I have to insist on being placed all the way to the left of the stage so no sound source is being directed at my left ear. I have trouble recognizing a well-known song being played as background music in a restaurant or store. I trialed some Bi-CROS HAs and I liked them, but my audi recommended against them because he was afraid that the remaining hearing I have in my left ear would be lost without the aural stimulation from wearing an actual HA in that ear. I’ve been considering getting Bi-CROS HAs in addition to my regular HAs. That way I could wear the Bi-CROS HAs only when I was performing.
It has been challenging for me as a musician. I would think that your possibility of improvement would depend on what caused your sudden loss. Please let me know if I can answer any questions or help further.
