Term
| What are some benefits of binaural hearing? |
|
Definition
| Improved speech perception in quiet and in noise, improved sound localization, ease of listening, perceived benefit and satisfaction, and quality of life |
|
|
Term
| What are some disadvantages of bilateral fittings? |
|
Definition
| Cost, binaural interference, self-image, wind noise, aid management, and occlusion effect |
|
|
Term
| When one ear fit in a bilateral fitting actually makes speech understanding more difficult than when the better ear is fit only with a hearing aid |
|
Definition
|
|
Term
For a patient with hearing thresholds that are different by ___ dB or speech discrimination scores that are different by more than ___%, the following questions should be asked:
-Should a bilateral or unilateral fitting be recommended?
-If a unilateral fitting is recommended, which ear?
-Should a CROS, BICROS, or FM system be used? |
|
Definition
|
|
Term
-If each ear considered in isolation is aidable, then assume that a patient should consider a ___ fitting
-The ___ the loss in the better ear, the greater the possibility that a bilateral fitting is the best option |
|
Definition
|
|
Term
| What questions should you ask yourself when asking which ear you should fit? |
|
Definition
-Which hand does the patient have the better dexterity?
-Which ear displays better speech scores?
-Are there complications in either ear canal?
-Do they use a certain ear more? |
|
|
Term
| If there is no advantage or difference between the ears, select the ___ ear due to ___-ear advantage for most patients |

Some common characteristics for children with ANAD are...
-Inconsistent responses to ___ (but some are consistent)
-Speech understanding ___ than predicted by audiogram (but not always)
-Speech understanding poorer in the presence of ____ ___ (almost always)
-Often difficult to learn spoken language through ___ alone (but it can happen)
-Range of ___ quality (variable from day to day). |
|
Definition
| sound poorer; background noise; listening; vocal |
|
|
Term
| The SPL, across frequencies, measured in the open (unaided) ear canal for a given input signal. |
|
Definition
| Real-Ear Unaided Response (REUR) |
|
|
Term
The gain provided by the pinna and the ear canal with consequent head diffraction effects as measured in the ear
canal. Subtract the input signal level from the REUR across frequencies to obtain the REUG. |
|
Definition
| Real-Ear Unaided Gain (REUG) |
|
|
Term
| The frequency response of a hearing aid that is turned on, measured in the ear canal, for a particular input signal. |
|
Definition
|
|
Term
| The gain of the hearing instrument across frequencies, measured in the ear canal. Subtract the input signal level from the REAR across frequencies to obtain the REAG. |
|
Definition
|
|
Term
The amount of gain provided by the hearing instrument alone
calculated by subtracting the REUG from the REAG across frequencies or by subtracting the REUR from the REAR across frequencies. (REIG = REAG – REUG) |

Term
-A price-value mismatch exists in the mind of the consumer and is when the ___ for something does not equate to the ___ of the product or service
-There is a price-value mismatch in patients’ minds between ___ of and ___ of digital hearing aids |
|
Definition
| price; value; costs; value |
|
|
Term
| are tasks completed by theaudiologist to ensure a well-fitted hearing aid |
|
Definition
|
|
Term
are assessment made by the patient using outcome measures to determine if hearing aids have made a difference in their
lives |

Term
When a HA user is experiencing feedback you can...
-Ensure that the real-ear aided gain has no excessive ___. If so, ___ them, but realize that it may result in targets not being reached
– ___ the size of the vent or change from an ___ to a ____ dome which may exacerbate the occlusion effect (The low frequency gain of the hearing aid may need to be reduced)
– Decrease the ___ frequency gain of the hearing aid or the high frequency ___ ___ or ___ the high frequency compression threshold in the relevant channel with understanding that it may affect speech intelligibility or affect sound quality
–___ or ___ the earmold or earshell realizing it takes extra time and expense
– Change to a hearing aid with a more effective feedback ___ algorithm |
|
Definition
| peaks; dampen; Decrease; open; closed; high; compression ratio; increase; Remake; recoat; cancelling |

|
Term
When a hearing aid user says that their own voice sounds hollow, boomy, and/or like speaking in a barrel and other voices don't sound that way then...
-The hearing aid amplifier is excessively amplifying ___ frequency sounds
-The patient may have ____ what their own voice sounds like
-The earmold is excessively ___ the ear canal
-The vent is too ___ |
|
Definition
| low; forgotten; covering; small |
|
|
Term
| In all of the studies comparing gain obtained with manufacturer's best of first fit algorithms, how did the prescribed gain differ from that obtained with real-ear measurement? |
|
Definition
| Gain tended to be overestimated |
|
|
Term
| T/F: For children with ANAD who didn't receive adequate benefit from HAs, cochlear implants can actually help the auditory nerve function better |
|
Definition
|
|
Term
| T/F: Parents of children with ANAD have greater anxiety than peers with children who have SNHL because their child's prognosis is more uncertain |
|
Definition
|
|
Term
| T/F: Anytime an audiologist increases gain, works with venting, etc., it is important to run the feedback canceler |
|
