A new modification of the Rinne test.

Area of Science:

• Audiology
• Otolaryngology
• Medical Diagnostics

Background:

• Rinne's test is a standard audiological diagnostic tool.
• The test's effectiveness is influenced by tuning fork application force, which is often imprecisely defined.
• Accurate force measurement is needed for reliable results.

Purpose of the Study:

• To develop and evaluate a modified tuning fork for precise force measurement in Rinne's test.
• To determine the optimal application force for improved diagnostic accuracy.

Main Methods:

• A modified tuning fork capable of measuring application force was designed.
• Rinne's test was performed on 100 ears with confirmed conductive hearing loss.
• Three distinct forces were tested: 400 g (light), 2400 g (firm), and a clinically typical indeterminate force.

Main Results:

• The application of 2400 g (23.5 N) firm pressure demonstrated superior sensitivity, specificity, and accuracy.
• Lesser forces resulted in reduced diagnostic performance.
• Precise force measurement enhanced test reproducibility and result comparability.

Conclusions:

• Optimal force for Rinne's test is 2400 g (23.5 N).
• Standardized force application significantly improves the diagnostic value of Rinne's test for conductive hearing loss.
• This modification offers a more reliable and reproducible method for audiological assessment.
