Re: how loud is 105db?
Yup every 3db is a doubling of volume but only electronically measured with no weighting.
For a percieved doubling in volume a 6-10db increase would be required. This is because the human ear automatically attenuates low frequencies. So V-Twin are generally much quieter to the ear than a screaming IL4.
Ever noticed how you hear a V-Twin rev and you smile where as an IL4 you wince???
