The applicability of the modified bivariate plotting procedure to subjects with functional hearing loss

Area of Science:

• Audiology
• Hearing Science
• Diagnostic Testing

Background:

• Functional hearing loss presents diagnostic challenges.
• Accurate identification is crucial for timely intervention.
• Existing audiological tests may have limitations.

Purpose of the Study:

• To evaluate the effectiveness of a modified bivariate plotting procedure.
• To assess its applicability in diagnosing hearing loss in younger adults.
• To determine the diagnostic accuracy, including false-positive and false-negative rates.

Main Methods:

• The modified bivariate plotting procedure was applied to subjects under 44 years old.
• Participants had diagnosed functional hearing loss.
• Performance was measured by false-positive and false-negative rates.

Main Results:

• The procedure demonstrated a 0% false-negative rate.
• A 17% false-positive rate was observed.
• This accuracy applied to both significant and mild/high-frequency sensorineural hearing loss.

Conclusions:

• The modified bivariate plotting procedure is a reliable tool for identifying functional hearing loss.
• Its 0% false-negative rate is particularly valuable for ensuring all cases are detected.
• Further research may explore optimizing the procedure to reduce false positives.
