Request for Audiological Testing Prior to NeuroNet Evaluation
Download the print version of this list to take to your audiologist.
-
Tympanometry: run each ear twice to ensure reliability
- Is middle ear pressure NeuroNet normal? (MEP equals -25 daPa to 15 daPa)
- Is the eardrum compliant? (SC equals .5 to 1.5)
-
Acoustic reflex thresholds:
- Are ipsilateral and contralateral reflexes present at 500, 1000, 2000 and 4000 hz?
- Does the response onset and offset correspond to the tone onset and offset?
- Are the reflex thresholds between 90 and 100 dB?
- Are contralateral reflex thresholds no more than 10 dB above ipsilateral?
-
Otoacoustic emissions
- Are emissions present across the frequency range in each ear?
- Is emission amplitude normal (not excessively large)?
-
Audiogram: air conduction
- Can this patient hear soft sounds (15 dB or softer) across the frequency range?
- Can this patient wait, listen and respond accurately to soft sounds?
- Audiogram: bone conduction (When air conduction thresholds are 20 dB or greater)
- Speech discrimination: at low intensity (35 dB) and at 0 to 5 S/N ratio
- Dichotic words dichotic digits (up to age 7-8); double dichotic digits (8 or older); SCAN C; SSW. Do at least 2 of these dichotic tests.
- Can the patient do the test without stopping the tape?
- Are there significant reversal errors?
- Are test scores within normal limits for all conditions?
-
ABR: Auditory Brainstem Response: (only test as needed; especially needed if there is a binocular vision problem)
- Is there binaural summation (better response with two ears than with only one)?
- Is the quality of the waveform maintained for fast click rates? For loud clicks?
