Why is it ##\log_{10}## ? I don't see that anywhere in the formula the professor gave us (up top)?

Okay - what you said (in your last post) makes sense - I was just explaining it in a way that made sense to me, (although it was wrong.) Judging by what you said here about ##d_r## - am I right in how I built this equation? dBSPL = dBr - 20log(di/dr), I think that it goes like this = 80 -...

I thought quite a lot about this prior to posting actually, and I tried to write this down in a formula, but I got stuck - because my book shows Intensity as: Intensity = Energy / (Time * Area) In the question from my textbook, no Energy or Time is given, so how do I figure out a change when...

Homework Statement The sound pressure level is 80db at a distance of 30 meters. What is the dBSPL at 60 meters? Homework Equations My book has provided me the following formula: dBSPL = dBr-20log(di/dr) - but it has not explained what "di" and "dr" are.The Attempt at a Solution I've been...
