NBC HIS TEST PAPER 2025/2026 QUESTIONS WITH
SOLUTIONS RATED A+
✔✔Type A Tympanogram - ✔✔Indicates normal eardrum and middle ear function
Normal tympanic pressure peak and normal static compliance no air-bone gaps.
✔✔Type As Tympanogram - ✔✔Low compliance, stiff may result in air-bone gaps can
be seen with otosclerosis or ossicular fixation, atypically low PMC
✔✔Type Ad Tympanogram - ✔✔Hyper-compliant. May result in air-bone gaps. Can be
seen with ossicular discontinuity, atypically high PMC
✔✔Type B Tympanogram - ✔✔Markedly non-compliant stiff, air bone gaps are typical
usually the result of middle ear effusion or significant TM scarring
✔✔Atypically large ECV - ✔✔Changes in the external ear canal pressure do not result
in changes in compliance
✔✔ Most common cause of hearing loss at 4000 Hz - ✔✔Acoustic Trauma
✔✔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
