I developed a few tests but they are too long. I am looking at alternative solutions.
Have you tried to search on brain auditory evoked potentials? Pretty much sure there is something on this topic.
My Z-Bell Testing is a quick screening that we use with brain injured people. 6 minutes for the "quick and dirty" pass/fail which category (autonomic or central nervous system) is the culprit. 10 more minutes for a more detailed evaluation of how to remediate the auditory filtering ability.
I wish there was more time. I love to collaborate. When my next grant goes in I will contact you.... what a great idea! Thank you!.
Hi Karen, This is part of the ER routine. I was looking more for a cross modal or auditory test that may relate to recovery. Hinting towards a biomarker type.
Hi Gabriela,
I think it depends on what type of injury you are trying to assess.
If a patient has a temporal bone fracture and auditory nerve injury, probably simple audiometry is the best test.
If you want to see the effects of global traumatic brain injury (central, not peripheral injury) on hearing, a more cortical test like the dichotic listening test might be useful.
Traumatic brain injury is such a heterogeneous illness. Some patients may have an epidural hematoma and can be totally fine after surgery. Others may have diffuse axonal injury and can be comatose for a while. They then may wake up with attentional issues - the dichotic listening test might pick up on that. Similarly, some people with "concussions" have trouble focusing and paying attention after their injury. Dichotic listening test might pick up some auditory attentional issues.
Hope that is helpful.

I usually use the test on the Dean - woodcock neuropsych battery. You simply stand behind the patient and rub you're thumb and forefinger together on either side of the head next to the ears and ask if the person to tell you which ear, right, left, or both hears the sound
You may want to take a look at the Ling 6-Sound Test Everyday.
http://www.audiologyonline.com/articles/using-ling-6-sound-test-1087.
The examiner covers their mouth and says sounds and it is meant to judge if an individual can participate in a conversation. Dr. Parente's suggestion is basically a bone conduction assessment and the Ling would be looking at sensorineural.
