5.AUD-PTA

Audiology SLP314

QuestionAnswer
What is pure-tone audiometry? The measurement of hearing thresholds for pure tones of various frequencies using standardized equipment and procedures
What two things must happen before conducting an audiometric test? 1. Case history 2. Otoscopy
What 4 pieces of info should the case history collect? 1. Nature of hearing problems (past and present) 2. Family history of hearing loss. 3. History of noise exposure 4. Other medical probs and prior amplification
What two areas are inspected during an otoscopy? 1. Ear canal 2. Ear drum
What 4 things does otoscopy look for in ear canal? 1. Foreign objects (esp. children) 2. Ear wax (refer for cleaning) 3. Inflammation/irritation 4. Dried blood
What does otoscopy look for during ear drum inspection? 1. Coloration 2. Distension/ bulging 3. Fluid 4. Scars or tears 5. "Cone of light" (healthy)
What instrument measures pure tone hearing thresholds at various frequencies? Audiometer
What does 0-dB HL represent? Normal-hearing sensitivity for the average young adult ear.
What frequencies are tested during pure-tone audiometry? 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, 8000Hz
What is the decibel range on an audiogram? -10 to 110 dB
What term refers to physical measurement of sound with meter? dB SPL (sound pressure level)
What intensity measure do audiometers use? dB HL (hearing level)
What frequencies does the human ear hear more easily? Middle frequencies.
What frequencies require greater intensity for the human ear to hear? Low and high.
What is an audiometric threshold? Level at which tones are heard 50% of the time.
What is the difference in max intensity output between air conduction headphones and the bone vibrator? AC = 120 dB BC = 50-75 dB
What frequency and intensity level does an audiometry test begin with? 1000Hz at 30dB
If a tone is heard, decrease or increase intensity at what interval? Decrease by 10dB steps.
If a tone is NOT heard, decrease or increase intensity at what interval? Increase by 5dB intervals.
When should hearing threshold be recorded? When patient indicates hearing 50% of the time (2 out of 3 or 4 presentations).
What are intermediate frequencies and when should they be tested? Intermediate frequencies are semi-octaves (half-way between standard testing frequencies). Test them when threshold difference between octaves is 20dB or greater.
How do you calculate pure-tone average? Average of AC thresholds at 500, 1000, and 2000 Hz.
What range is normal hearing? -10 to 15 dB
What range is slight hearing loss? 16 to 20 or 25 dB
What range is mild hearing loss? 20 or 25 to 40 dB
What range is moderate hearing loss? 41 to 55 dB
What range is moderate-severe hearing loss? 56 to 70 dB
What range is severe hearing loss? 71 to 90 dB
What range is profound hearing loss? > 90 dB
What is degree of hearing loss based on? Pure-tone average (PTA)
What are three types of hearing loss? 1. Conductive 2. Sensorineural 3. Mixed
