Got into Prius "quietness" discussion. Need some help on dB.
Discussion generated desire for some 'rules of thumb' regarding dB. eg one person suggested every 3 dB increase equals doubling the volume of sound. :?:
Is that reasonably accurate ? That would say that 63dB is twice as loud as 60dB, and 66dB is twice as loud as 63dB. Can that be right ?
Accurate or not, can some of you help me, in laymen terminology, with some rules of thumb for relative dB numbers. ?
no logarithms (sp?), formulas, math, :roll: please. I appreciate & understand the relationship is not linear.
for example, what is the difference in loudness btwn 65dB & 70dB; btwn 65dB & 75dB... etc.
thanks !!
