1. The problem statement, all variables and given/known data In general, if a sound has intensity of beta dB at 1 m from the source, at what distance d_0 from the source would the decibel level decrease to 0 dB? Since the limit of hearing is 1 dB this would mean you could no longer hear it. Express the distance in terms of beta. Be careful about your signs! I know that the relationship between the intensity and distance is an inverse square relationship, but i'm not sure what exactly the question is looking for. Do i have to find the distance when it goes to 0 or to 1 ? Because if that is zero, then even after 100m, the intensity wouldnt be zero ? im confused !
