Hearing Measurement Assessment Check List
Can you…
• Give the instructions for performing air conduction pure-tone audiometry, place the earphones on the patient?
¨ Instructions emphasize listening for soft tones, guess if necessary, how to respond to tone
¨ Earphones on proper ear
¨ Earphones aligned properly
¨ Cords in back
¨ Patient at right angles to tester
¨ Patient has response button (if required by instructions)
• Obtain an air conduction pure-tone threshold for the right or left ear at 1000 Hz (or any other frequency) using a pulsed or continuous tones, record the audiometric symbol on audiogram?
¨ Right (or left) ear button selected
¨ Tone button selected
¨ Pulsed or continuous tone selected
¨ Correct starting level
¨ Adjust HL control appropriately, presents tone correctly
¨ Use ascending procedure correctly
• Obtain bone conduction thresholds?
¨ Instructions emphasize listening for soft tones, guess if necessary, how to respond to tone
¨ Bone vibrator on proper ear
¨ Placed on mastoid, no hair underneath, or touching pinna
¨ Cord in back
¨ Patient at right angles to tester
¨ Patient has response button (if required by instructions)
· Obtain an SRT for the left or right ear? Adjust the level of your voice?
¨ Mic button selected
¨ Correct ear selected
¨ Correct distance to microphone
¨ Good level of vocal effort
¨ Gain control adjusted (if needed)
¨ Correct starting level
¨ Adjust HL control appropriately
¨ Choose correct words (spondees)
• Do word recognition testing? Based on the SRT you just obtained for the left ear, select the presentation level. Present only the first 5 words.
¨ Correct dB level chosen (40 dB SL re: SRT just obtained)
¨ Correct settings for doing WRS
¨ Correct word list selected
• Calculate the WRS for full or half-word lists (25 words)?
¨ For example, if 3 words were missed out of 25 presented, what's the WRS? If 5 words were missed?
