  1. a -UCL: speech

    -LDL: tone

    -60 dB or below, dynamic range is small between quiet and loudest sound.
  2. b Look for the length of the dynamic range
  3. c -Tell me when you barely hear it, clearly hear it, it's loud, it's almost uncomfortable, it's painfully loud

    -May not do all the middle ones, unless we are doing a hearing aid
  4. d - Put 2 sounds in and you measure if a third sound comes out

    -Typically screen with DP, to look at specific frequencies
  5. e Normal hearing: Barely hear it = 0 dB & Painful = 100-110 dB

    -W/ Recruitment - Must go from barely hearing it to painfully loud within a very small dynamic range (40 dB range)
  6. f 1. Plays and ongoing sound at a specific loudness, start at about 10 dB above

    2. Increases by 1 dB 20 times, if they raise their hand saying they heard the difference they heard the difference
  7. g -Looks at the OHC movement

    -We can measure the outer hair cell function (assuming they have a normal tympanogram)
  8. h That it will take a while before they can hear it, but they will hear it b/c they will have recruitment
  9. i -If they sound goes in and the OAEs come back out = IHCs are damaged

    -If the sound goes in and NO OAEs come back = OHCs are damaged - Suggesting Cochlear/Sensory loss and they have recruitment
  10. j Determines if the patients is able to notice a 1 dB increment change (JND)
  11. k -Most people with normal hearing will not be able to hear a 1 dB difference, can tell about 7 times, but not all 20

    -If they have recruitment, they will be able to respond to more than 7 and they have a cochlear/sensory loss b/c they have a small distance b/w being able to hear it and it being too loud
  12. l Put click that stimulate the cochlea at the whole time and measures what comes out
  13. m 1. Compare to ear that has a hearing loss

    2. Complete recruitment = when the bad ears hears the same as the good ear - It has to get smaller and smaller units to match the loudness perception
  14. n Use if they have one normal ear and one bad ear, to look for recruitment
  15. o Caused by the loss of OHC
  16. p -Do we have that smaller dynamic range

    -They may have a reduced dynamic range b/w where they can finally hear and where it becomes painfully loud
  17. q ...
