Interpreting Audiograms

Question 1

Calculating Pure Tone Average(PTA)

Answer 1

Average the hearing thresholds at 500Hz, 1000Hz, and 2000Hz

Question 2

Compare PTA to SRT

Answer 2

Check if PTA and Speech Recognition Threshold (SRT) match (within 10dB) to verify test reliability

Question 3

Identify Impairments and Limitations

Answer 3

• Impairment of Structure: Physical issues in ear anatomy
• Body Function Impairment: Functional hearing loss
• Activity Limitation: Difficulty in tasks due to hearing loss (use speech test results)
• Participation Restriction: Challenging in social or work settings, considering Contextual Factors (personal and environmental)
