    There seems to be a missing piece of information. Unless you also know either the intensity recorded by the second observer or the intensity generated at the speaker, it's not possible to answer this. Are you sure you typed in the question completely?

    If someone is weak in intensity, does that mean they're not very bright? :) Sorry, I couldn't resist the pun. LOL.
