What type of hearing loss and degree lost I have?

My hearing loss type is sensorineural hearing loss in both ears. What is a sensorineural hearing loss? My inner ear from my brain to hear the sound and speech is damage. I noticed that I can't understand speech sound especially hear high frequency sounds in the vowel letters. I always have trouble understand children, women, and foreign people's voices when I try to hear them. I have to lip read people lip to understand what they are saying even the sound doesn't sound right.

At the age 3, my degree hearing loss was mild to moderate through my early stage. I did lost some more hearing when I reach to my teenagers years. I went to moderate hearing loss. I didn't take my hearing test for a long time and found out that I lost some more. Today, I have moderate to severe hearing loss (very close to severe). I hope I won't lose anymore.

Since I am hard of hearing person, I also follow same way the normal hearing people do to protect hearing. The only way I can protect rest of my hearing what I have left, I have to follow these steps by low the volume down, turn to the left, get away from loud music, and use my Zune player for little while.
