- How does one determine the dB of a leaf blower.
- Relevant Equations
- db = 10log(p1/p2)
I have a leaf blower that states the sound level is 75dB. My question is, at what distance is this measured. It seems that as you get closer to the source, the dB number will increase drastically. If I double the distance from the source, then the power should go down by a factor of four or 6 db. Is this correct?
