Solve Hard of Hearing Question: Increase dB for Hearing Aid?

[emma123]

hi, I'm having trouble with a question and i was wondering if anyone can help me out. "To a person who is hard of hearing, normal conversation (60dB) sounds like a soft whisper. What increase in sound levels (in dB) must a hearing aid provide? How many times must the sound wave pressure be increased?" thanx
