Yes for both. But it mainly amplify the sound. It also cut out the background noise such as wind which sound much like static. There is mult program inside it as I could turn it to a certain program and it block everything while I can hear only telephone or headphone when I listening to my MP3. I am more then 80% lost in my ears so it help. My brother that is hearing wear my hearing aid one time. He say that little pup that was half block away sound like a great Dane next to his ear...lol.

The pitch black would kill me. I need light and dark together. If I was in room with pure light. It would burn me but I be weaker in pitch black as I wouldn't be able to hold my form together well if I use my ability.
