Log distance

  1. Apr 28, 2004 #1
    Hi there, first post from me - hurrah!

    I'm currently conducting an experiment measuring sound attenuation. I've got a table for the varying distances that measurements have been taken at, and the corresponding peak voltage values taken from a CRO. I understand that I have to take the log value of the voltage over voltage at 0m - this produces the answer in a dB ratio. I am also, however, required to draw a graph of dB (20log Vmic/Vmic@0m) against log distance.

    I understand that "20log Vmic/Vmic@0m" gives me dBs - but does log distance have any bearing on the experiment? In other words.........

    20log Vmic/Vmic@0m is to dB as log distance is to ?????????

    Thank you for your time!

    Regards,

    Rich.
