You are trying to overhear a juicy conversation, but from your distance of 16.0 , it sounds like only an average whisper of 20.0 . So you decide to move closer to give the conversation a sound level of 65.0 instead.

How close should you come?

    Your school subject is NOT college.

    You need to include the dimensions of the numbers you are quoting. Is the distance in meters? Is the sound level in decibels? Whatever it is, say so.

    A 45 dB increase in sound level is a factor of
    10^4.5 = 31,620
    increase in sound power per area.

    Use the inverse square law to see how close you have to get
