19 True/False questions

  1. What is true of audiometer calibration?intensity is represented in dB HL


  2. What is true of an audiogram?intensity is represented in dB HL


  3. Damage to the middle ear, with an otherwise normal auditory system, would cause what type of hearing lossthe outer and middle ear


  4. What is PTA? (pure tone average)the average of the pure tone thresholds at 500, 1000, and 2000 Hz in each ear


  5. A client with a threshold of 45 dB HL at 1000 Hz in the right earshows hearing sensitivity that is 45 dB worse than the average normal threshold for that sound


  6. The dB HL scalethe decibel scale shown on the audiometer dial or screen; allows for comparison of the client's thresholds to average normal thresholds


  7. What is the purpose of the case history interview?to establish positive interaction between the clinician and client, obtain information that might indicate potential causes of a hearing loss, indicate whether there is a need to modify test procedures, help determine the day-to-day effects of hearing impairment on the client


  8. When both air and bone conduction thresholds show hearing loss and thresholds for bone conduction are significantly better than for air conduction, what is the type of hearing loss?mixed


  9. In pure tone threshold testing, the starting intensity level shoulda behavioral response


  10. What does bone conduction testing measure?the sensitivity of the sensorineural portion of the auditory system


  11. Air conduction thresholds outside of normal limits indicate what?that there is a dysfunction at some level of the auditory system


  12. Children at ages 5 months to 2 yearsthe average of the pure tone thresholds at 500, 1000, and 2000 Hz in each ear


  13. Puretone threshold testing requiresa behavioral response


  14. On an audiogram, a sensorineural hearing loss is present whenmay not understand even amplified speech


  15. The conductive portion of the auditory system includesthe outer and middle ear


  16. NOT a component of the basic audiological evaluationelectronic calibration is required on a yearly basis, or sooner if audiometer malfunction is suspected


  17. When establishing pure tone hearing thresholds for a new patient, the examiner SHOULD NOT do what?mixed


  18. A false elevation of low-frequency hearing thresholds would likely occur due to what?high background noise level in the testing environment


  19. A person with a profound hearing lossmay not understand even amplified speech
