[QUOTE="Sean Thomas, post: 137833, member: 5801"] Re: dB calculations Tim, I understand your example, it's the same as the post on the dB Technologies forum. So you are saying that the two 134dB subs will put out 140dB (+6dB) and that the OSHA web site is wrong? Mark, I have been reading about log10 vs log20 calculations. Very interesting. So the next question is when do you use which calculation? The OSHA site is obviously using log10 for it's calcs, why 10 and not 20? [/QUOTE]
