| What are the indications for needing an Auditory Brain Response test? |
|
Definition
|
Auditory Brain Response shows the activity of the cochlea, auditory nerve, an auditory brainstem. Client is asleep or relaxed, 3-4 electrodes placed, looks for low impedance values

|
Term
|
Definition
|
Normal ME pressure but very high ME compliance, too much mobility disruption of ossicular chain.

Term
| What is the Acoustic Reflex Threshold? |
|
Definition
| The softest intensity level at which the acoustic relfex is present. Presenting a lot of different sounds to see the lowest relfex that stiffens the ME. |

- In what ways can the Immittance test procedure help you as a speech language pathologist or DHH teacher?
|
|
Definition
|
SLP- Know how it’s going to affect their speech stimulus. The child is not benefiting from normal speech, if there is fluid in the ear and amplification is needed.
DHH- OE & ME fluid means a regular hearing aid is not going to benefit. Hearing Aid is fit when there is no fluid. Get the information needed to know about your students
with and without amplification, how well can they hear you.

Definition
1. Detect perforations (holes) in the TM
2. Check the PRESSURE EQUALIZATION (P.E.)Tubes.
3. Detect any traces of FLUID in the MIDDLE EAR.
4. Detect stiffening or breaking of the OSSICULAR CHAIN.
5. Detect any dysfunction of the AUDITORY TUBE.
6. Measure EAR CANAL VOLUME.
7. Useful in POST-OP Surgical Evaluation. |
