How distance effects isolation
Posts: 1
June 25, 2016 - 7:20 am


In theory, If I have a full range sound (lets say a rock band) playing at 120db outside on the grass with no walls, is there a way to measure how much reduction in decibels would occur per foot of distance? Or is it source dependent needing to measure the db at 1 foot away from the source and then figuring out the attenuation by doubling the distance?

Im just curious if I can get an idea of how much isolation I would need in order to get down to a specific db by my property line.

It is best to do a seven day noise time study yourself. You will measure frequency and SPL over a seven day period using an iphone. What is the noise source and who is the receiver?
