I'm a musician and engineer in the US and I have chronic problems with a perforated eardrum and tinnitus. I just started going to see an otoneurologist who was finally able to have a discussion with me about my peculiar anatomy and what mechanical structures in my ears were the likely cause of my issues and what we could potentially do about them to improve and then preserve my hearing. We talked for 45 minutes with otoscope pictures of my ear canals and compared them to his. I'm going in for a Ct scan in a couple of weeks to confirm what he thought we could see from the outside, mainly that my last surgery (by someone else) put my eardrum too far forward and it isn't properly connected to the bone, and that in my other ear the location of my perforation makes a mutipath distortion problem because sound waves are also hitting the wrong end of my cochlea.

How do I know if I'm actually getting B20 at the biodiesel pump instead of B5 or straight diesel?

A lot of that smell depends on the pulping process they use. Kraft process is the stinky one. Sulfite isn't quite as bad, and thermi-mechanical doesn't really smell much.

(My father was a paper process chemist at a mill that did Sulfite and thermi-mechanical and I visited the plant a lot. The competing plant across town was a Kraft mill that reeked.)
