Vestibukar Exam Questions Flashcards
When asked to describe the hearing loss
- The type of hearing loss (SNHL)
- Mild to moderate
- Any other testing (tymps was done sand results are bnirmal/normal)
- Results are normal/ abnormal.
- What does the HL indicate? (Normal middle ear, abnormal middle ear, infection)
History examples:
Family history - see any conditions and any undiagnosed mild HL
Hearing concerns at home and at school
NHSP
Speech and language concerns
Is there any further testing that we can do aside from behavioural test
Speech testing or OAEs helps use a battery approach and functional difficulties in every day life.
Proffessionals that help alongside an audiologist
- ENT
- Paediatrician
How to condition a patient to a task. (6 marks)
- Condition needs to be performed at a supra threshold limit.
- The first task can be performed so that the task is understood and that demonstrated what to expect.
3.the infant needs to be told to wait for the sound when it is their turn - Each time the child responds you praise them appropriately
- If the child plays without no sound, you tell them to wait until the sou; is heard, so repeat any mistakes to condition them well.
What are some issues with sound field testing?
- Does not tell you information of the hearing loss or indicative SNHL
- Also goes to both ears at the same time so loss could be unilateral, or bilateral.
Hearing validation and its uses
1) Questionnaires looking at hearing range in a specific situation
2. Ling sounds* tests aided hearing across a range of of frequencies using speech sounds and listen and drop game.
3) aided speech tests* Mcormick Test or FAAF, shows the abi,it’s to discriminate between speech sounds. Shows that side h is being understood as well as detected.
4) aided gain* looks at the quietest sounds that child respond at with aids on and being tested in a sound field.

When the child is three years old, what behavioural test can we do?
Play Audiometry
What is the principle behind VRA
A child will locate to a sound source, the orientation response if it hears it.
Discuss the type of choice if stimuli for VRA or why is it that VRA work?
The conditioning stage is of
classical conditioning where a relationship is established between the sound stimulus and a reward this is
now–conditioned orientation response the COR.
For VRA the reward and stimulus do not
need to be spatially the same and removing location makes the test more operant in nature.
The OR will habituate so strong re-enforcement is needed.
What is the choice of stimuli and reinforcer that is used for VRA?
Narrow band noise/Warble tones so no standing waves that would be present with pure tones. Re-enforcer
should be interesting as the more interesting the more location responses you will get.
What are some issues with VRA
Does. It tell if the loss is conductive or sensoneural HL or unilateral or bilateral
Things to check before doing VRA on a child?
If the child’s neck is able to move left or right and check with the parent.
Also check otoscope and do otoscope questions
What are some next steps after doing VRA to determine and diagnose the hearing loss?
1) Insert phone VRA - this is more preferred than heard phones and you get preferred ear results (unilateral/bilateral)
2) BC - tell us if the loss is conductive or SNHL
3) tympanimetry - help find out if the loss causes middle ear problems
