A mother comes in worried her hearing is worse since the birth of her first kid what is likely happening -
✔️✔️Otosclerosis
A large dip in the 6000Hz in only one ear with positive tone decay is indicative of - ✔️✔️Possible retro-
cochlear tumor
Patient comes in complaining his hearing aids worked fine until they were cleaned, now they are weak
and feeding back what is the likely cause of this problem - ✔️✔️Receiver tubing is pushed in
How does an osteoma present - ✔️✔️Bony growth in external auditory canal
This is a correct answer
Which validation method can be effectively performed in a sound field envoirnment? - ✔️✔️NU-6
Which sound field test determines the benefit of directional microphones - ✔️✔️QuickSIN
acoustic impedance - ✔️✔️resistance a material provides to the passage of sound waves
During otoscopic inspection what is not a contraindication - ✔️✔️Compliance of the tympanic
membrane
What two thing verifies an audiogram - ✔️✔️SRT and PTA have to agree (Must be within 5-10 decibels
of each other
A patient brings his hearing aids in to be cleaned and sets them on the counter what type of
transmission should the receptionist be concerned about - ✔️✔️Indirect Transmission
, A patient comes in for a hearing evaluation otoscopy was clear and the results showed symmetrical
precipitous high frequency hearing loss what type of coupler should be used - ✔️✔️Open-dome
A patient comes in for a second follow-up and complains that sounds like the furnace and the fans are
too loud and annoying which feature should be adjusted? - ✔️✔️Expansion
Extending a receiver tubing past the isthmus will have what effect - ✔️✔️Give more high frequencies
give more power help with feedback and wax
What does the microphone do in a hearing aid - ✔️✔️Transducer that changes acoustic energy-
electrical wave form
Output - ✔️✔️The highest intensity that the hearing aid can produce
Small diameter tubing has its greatest effect on - ✔️✔️Decreasing High frequency gain
A patient has a severe to profound loss and doesnt mind a RIC/BTE what mold should be made -
✔️✔️Full-Shell
otosclerosis - ✔️✔️hardening of the bony tissue of the middle ear, seen more often in women than
men represents, type As tympanogram is expected
Otitis Media: - ✔️✔️BC= normal AC= Reverse slope- Type B tympanogram
Cookie Bite - ✔️✔️This audiogram is a congenital pattern that can progress quickly over time, speech
discrimination may be good, Type A tympanogram
Mumps AKA: Single Sided Deafness - ✔️✔️This pattern is referred to as Single Sided Deafness or
Unilateral Hearing Loss, The key is recognizing this in the case history. The person should report they
have had this for many years or all their life. Still shows type A tympanogram.The ipsilateral acoustic
reflex isn't working properly or is absent all together.
