Unit of sound/noise is decibels

  1. Sep 5, 2008 #1
    Hi all,i am extremely sorry that i am asking a very basic question,The unit of sound/noise is decibels,but unit of attenuation is also decibels/length, so how it could be possible as two are different things.

    Re: Attenuation

    I don't understand your question. You have two different quantities, each with its own units. Decibels is not the same as decibels/length.
