Ear canal S bend geometry?
I am training to become an audiologist ... the theory is no problem, but the practical side is a bit more difficult!
I am now having to learn how to take ear impressions ... but the geometry of the ear canal is defeating me.
It's supposed to be S shaped ... but how does this S shape oriented? Vertical? Horizontal? Tilted?
And where the heck are the "first bend" and the "second bend"?
Any help most welcome!
[I have searched the Web far and wide - but could not find SPECIFIC details on the ear canal route]
