The antiphasic Chinese zodiac-in-noise (ZIN) test significantly improves hearing loss detection sensitivity compared to the diotic ZIN test. Binaural intelligibility level difference (BILD) shows promise as a sensitive indicator for hearing impairments, especially in low frequencies.
Area of Science:
- Audiology and Hearing Science
- Speech and Hearing Research
- Biomedical Engineering
Background:
- Antiphasic presentation has shown advantages in hearing screening tests like the digit-in-noise test.
- The Chinese zodiac-in-noise (ZIN) test is a tool used in hearing assessment.
- There is a need for more sensitive hearing screening methods, particularly for asymmetric and unilateral hearing loss.
Purpose of the Study:
- To evaluate if incorporating antiphasic stimuli in the Chinese ZIN test enhances its sensitivity for detecting hearing loss.
- To investigate the relationship between binaural intelligibility level difference (BILD) and hearing thresholds.
- To assess the potential of BILD as an indicator for hearing loss.
Main Methods:
- Normative data for the antiphasic ZIN test were collected from 117 normal-hearing individuals.
- The antiphasic ZIN test was then applied to 195 participants with varying degrees and types of hearing loss.
- BILD was calculated as the difference between antiphasic and diotic ZIN test results and analyzed against hearing thresholds.
Main Results:
- The antiphasic ZIN test demonstrated higher sensitivity (0.88) compared to the diotic ZIN test (0.49) in detecting hearing loss greater than 25 dB HL in the poorer ear.
- BILD showed a stronger association with low-frequency hearing loss than high-frequency hearing loss, decreasing as impairment worsened.
- Partial correlation analysis indicated that BILD was comparable to hearing thresholds in its association with hearing loss, even after controlling for age.
Conclusions:
- The antiphasic ZIN test offers superior screening sensitivity over the diotic ZIN test, especially for asymmetric and unilateral hearing loss.
- BILD is a sensitive measure for low-frequency hearing impairments and shows significant potential as a hearing loss indicator.
- The findings support the use of antiphasic stimuli in ZIN tests for improved hearing screening.
