  1. all sounds have
    • loudness (intensity)
    • pitch (freq)
    • temporal (time) characteristics (duration)
  2. degree of loss
    • mild
    • moderate
    •  severe 
    • profound
  3. type of loss
    • conductive
    • sensorineural
    • mixed
    • dB is top to bottom
  4. degrees of hearing loss by the numbers
    • w/i normal limits=0-25, children it is 15
    • mild=26-40
    • moderate=41-70
    • severe=71-90
    • profound=91+
  5. what do auds test by
    air and bone conduction
  6. what does air conduction test
    • the degree of hearing loss, only air conductin testing is needed 
    • tests outer ear to nerve
  7. what does bone conduction test
    • determines the type of loss but must be done with air conduction
    • only tests the inner ear and nerve
  8. what is considered to be normal hearing
    • both ac and bc have to be under 25 db
    • a gap of no more than 5 db
  9. hearing threshold
    softest level at which a person respond to a sound 50% of the time
  10. conductive hearing loss
    • affects outer and middle ear
    • usually not permanent
    • often medically treated
    • left untreated loss can become permanent
    • AC is greater than BC and BC is normal meaning that it is below 25 db
  11. sensorineural loss
    • affects inner ear sensory and ore
    • auditory nerve
    • permanent hearing loss
    • not treatable with medicine but may be helped with amplification
    • in inner ear or nerve
    • BC AND AC are equal and not normal meaning that they are both below 25 db and are within gap of 10 db
  12. mixed hearing loss
    • combo of sensorineural and conductive
    • possibly medically treated (only be for conductive)
    • may affect outer, middle, inner ear and nerve
    • again AC is greater that BC and both are not normal, gap of 10 db or more
  13. when trying to figure out the degree of loss, what do you look at
    look at AC O OR X
  14. When you look at type, what do you look at
    look at bone conduction < (RIGHT) OR >
  15. what happens to an audiogram when combined with a speech banana
    • becomes a graph of speech loudness v hearing
    • soft speech is hard to hear
    • loud speech is easier to hear
  16. are vowels or consonants louder in pitch
    • vowels are lower in pitch and are spoken more loudly than consonants
    • all vowels are voiced and have a voice tract that is fairly open
    • consonants are higher in pitch meaning they are harder to hear
    • vowels also carry the power of the word, consonants carry the meaning
  17. most students with normal hearing usually hear about how much of what is said
    • 3/4 of what is said
    • depends on:
    • distance
    • noise
    • reverberation
    • and hearing loss
