High-frequency audiometry above 8,000 Hz

Area of Science:

• Audiology
• Human auditory perception
• High-frequency hearing

Background:

• Auditory sensitivity testing is crucial for diagnosing hearing impairments.
• Limited normative data exists for high-frequency (above 8 kHz) auditory sensitivity in young adults.
• Clinical audiometry procedures may need adaptation for high-frequency assessment.

Purpose of the Study:

• To evaluate the clinical feasibility of high-frequency auditory testing (8-20 kHz).
• To gather normative auditory sensitivity data in young adult females (19-22 years).
• To validate a modified clinical audiometry procedure for high-frequency assessment.

Main Methods:

• A modified Hughson Westlake procedure was used to determine auditory thresholds.
• Forty-one female university students (19-22 years) participated.
• Thresholds were measured for both ears across frequencies from 8 to 20 kHz.

Main Results:

• The modified procedure yielded reliable auditory thresholds.
• No significant differences in thresholds were found between the left and right ears.
• Only 52% of participants responded to the 20 kHz tone, indicating reduced sensitivity at this frequency.

Conclusions:

• The modified Hughson Westlake procedure is clinically feasible for high-frequency hearing assessment.
• Normative data for young adults at high frequencies were successfully collected.
• High-frequency hearing testing using adapted clinical methods is reliable and achievable.
