Stepping back from ANR
Roger, now you've got me thinking:-) As you say it's logarithmic but if I'm not mistaken 10w to 100w =10dbw, 10v to 20v = 20dbv. I don't know how ANR is measured so I'm guessing dba but it looks like double = 6db. In an expample I found on the web and you compare say the Rifle & Threshold of Pain there's 6db difference. That would suggest headphones with say 26db passive attenuation would reduce the sound level by a factor of 40. If you use 3db then it would be a factor well over 500 which I think would be unrealistic. David (GM3RFA) Oops!, that should have beeb a factor of 20 not 40 David
