Sound measure- simple question

  1. Nov 21, 2005 #1
    On a day when you are listening to music at a sound-level of 20 dB above the threshold of audibility, an average person would say that it was
    none of these
    very loud
    slightly loud
    of normal listening level
    very soft

    Well, for every 10dB increase we percieve sound as twice as loud right? So would that make this slightly loud? its only 4 times as loud as barely audible, or would that be considered normal listening level? i'm just not sure what to classify the sound as.

    You have the math right, but the qualitative response is just a bit arbitrary if you ask me >.<
