Hearing impaired since 4, deaf since 16, pianist since 3, AMA!
I started playing piano at age 3, diagnosed with bilateral sensorineural hearing loss at age 4, when I began to wear hearing aids.
At age 16, I quite literally woke up deaf, the ~25% of my remaining hearing having gone down to 3% while I slept.
I received a cochlear implant at age 17, I'm now 25, still playing piano. I can listen to music, dance, use a cell phone, tons of normal stuff.
Ask me anything!
Edit: okay, I need sleep! I'll reply to any further questions in the morning.
