whole system can be evaluated with speech test. Not only test because doesn’t show site of lesion. also need to figure out what the problem is tho.

where the problem is. also needs to figure out the problem tho

youre locating the problem in the outer/middle ear zone. The point to be taken is that the faulty middle ear has a direct consequence on the speech

Question 15

sensorineural loss

Answer 15

cochlear problems (think about what audiogram would look like)

Question 16

Auditory neuropathy

Answer 16

All of your nerve fibers have to function in synchrony for them to work. In some people this synchrony is lost cuz the nerve fibers don’t fire together.

Question 17

Ossicular chain discontinuity

Answer 17

A 10 db conductive loss isn’t gonna do that much. So you need a bomb to go off in your middle ear to have speech recognition problems. This makes the point that probs in different parts of the auditory system have to be of different magnitudes to effect communication. Conductive has to be massive problem, inner hair cells—if you’ve lost 40% youre in deep trouble. The farther up the system, the more complex the input processing gets, therefore they matter more

Question 18

TBI

Answer 18
