Homework Help: Intensity of sounds - Hearing Aid

  1. May 17, 2006 #1
    A person wears a hearing aid, which makes a sounds louder by 50 dB. This a) means the sound intensity is increased by 100,000 times.
    b) This also means that the amplitude of the soundwave is increased by ______ times?

    I know Intensity is portportinal to (Amplitude)^2... so does that mean I squareroot the 100,000 times of the intensity to find part b?
