    sound problem Matthew98

    Hi guys,

    Q: If the sound intensity is increased by a factor of 4, what is the increase in the sound intensity level?

    Is there a misprint in the question? I would have thought if sound intensity is x4 then sound intensity level is x4?

    If it is a misprint what could the Q be?

    thanks!

      When sound intensity is doubled, the intensity level is incresed by 3. So if sound intensity is up by a factor of 4, that corresponds to an increase in intensity level of 6Db??
