Common Signs of Central Hearing
problems
Talks or likes TV louder than normal
Unusually sensitive to sounds
Asks many extra informational questions
Confuses similar sounding words
Hears better when watching the speaker
Problems with rapid speech
Frequently misunderstanding instructions or questions
Porblems understanding in background noise
Problems with phonics or discriminating speech sounds
Frequently requests repetition.

Abbreviated Profile of Hearing Aid
Benefit
2/20/2013
Ease of Communication (EC scale)
I have difficulty hearing a conversation when Iām with one of my family
at home.
Background Noise (BN scale)
When I am in a crowded grocery store, talking with the cashier, I can
follow the conversation easily.
Reverberation (RV scale)
I miss a lot of information when Iām listening to a lecture.
Aversiveness (AV scale)
Unexpected sounds, like a smoke detector or alarm bell are
uncomfortable.

Assessment & Test
ā¢ Patient hears acoustic stimuli over
headphone (except 1st test āsees flashes).
ā¢ Has to react by pressing buttons.
ā¢ If pressed correct, speed/difficulty increases
ā¢ Through training/repetition patient will be
able to perform tasks faster and faster.

1. Visual Order Threshold..
ā is the minimum time at which you can separate 2 visual
stimuli
ā¢ This ability is very important for digesting written information
ā¢ Increase the speed with which the brain is able to digest and
process information.
2. Auditory Order Threshold..
ā is the minimum time at which you can separate 2 auditory
stimuli
ā¢ If it takes you too long, you may have difficulty differentiating
critical plosives b-d, g-k, or p-t from each other. Which results in
difficulty understanding
We assess, and customer
trains 8 CAP task (1-2)
19. SolutionforSensoryNeural

3. Spatial (Directional) Hearing
ā Is the minimum time difference at which you can localize a
sound
ā¢ Allows correct training of spatial (directional) hearing.
ā Very important to be able to perceive sounds and especially
language selectively
Ā» from different directions,
Ā» to be able to assign them
Ā» to ignore them as well.
4. Pitch Discrimination
ā is the minimum difference between two tones
ā¢ vital ability for differentiating vowels and decoding of voice
melody.
ā¢ extremely important for speaking as well as for understanding
We assess, and customer
trains 8 CAP task (1-4)
20. SolutionforSensoryNeural
HearingLoss
5. Rhythm
ā fastest rhythm you can follow
ā¢ Ability to convert perceived auditory stimuli as fast as possible
into movements.
ā¢ very important for thinking, speaking and writing
ā¢ To train hemispheric coordination.
6. Auditory Choice Reaction
ā separating two different tones and reacting as fast as possible
ā¢ Decisive for identifying time of Phonemes (spoken) and
graphemes (reading).
ā¢ To react fast and focused to auditory stimuli without visual aid
We assess, and customer
trains 8 CAP task (5-8)

7. Frequency Pattern Recognition..
ā quickly and accurately resolve auditory patterns
ā¢ An important pre-requisite for the segmentation of the
continuous stream of auditory stimuli during speech
identification and processing.
8. Duration Pattern Recognition..
ā quickly and accurately resolve auditory patterns
ā¢ An important pre-requisite for the segmentation of the
continuous stream of auditory stimuli during speech
identification and processing.
