      • Nausea
  • Population
    • Recent acoustic trauma
    • Barometric trauma
      • Weightlessness
  • Diagnosis
    • Malfunctioning inner ear
      • Overstimulation
    • Physical activity
      • Habituation
stenger testing
Stenger Testing
  • Symptoms
    • Tinnitus
    • Unilateral hearing loss
    • Sporadic pain
  • Population
    • Anyone
      • Children
      • Middle-aged industrial workers
  • Diagnosis
    • Pseudohypacusic
    • Normal ABR
    • Stenger test positive
stenger testing ii
Stenger Testing II
  • Auditory phenomena
    • Simultaneous bilateral tone presentation
      • 10 dB HL difference between ears
    • Only louder tone is heard
  • Stenger administration
    • Bilateral, simultaneous presentation
      • 10 dB HL difference between ears
      • Poorer ear presented at 10 dB HL, 0 dB HL in good ear
        • Adjust both ears analogous to normal audiometric threshold
    • Stenger negative
      • Response to good ear
    • Stenger positive
      • No response to threshold
bilateral pseudohypacusic
Bilateral Pseudohypacusic
  • Yes-No test
  • Procedure
    • Present tones above/below threshold in each ear
    • Subject: yes-no to each presentation
      • Temporal arhythmicity
  • Are no responses correlated to onset of presentations?
    • Best with children
pulse count method
Pulse-Count Method
  • Rapid succession of tones presentations
    • Arhythmic presentations
    • Vary ear of presentation
    • Tones above and below admitted threshold
  • Subject responds with the total number of tones heard
    • Does total correlate with actual tones presented above threshold
  • Modification
    • Present all tones above threshold
why choose psuedohypacusis
Why choose Psuedohypacusis?
  • Veteran benefits

      • Post WWII peak (half of reported cases)
      • Hearing histories for modern soldiers (1-4%)
