    Area of Science:

    • Audiology and hearing science.
    • Signal processing in auditory diagnostics.

    Context:

    • Standard audiometry methods have limitations in accurately assessing hearing impairments.
    • Accurate detection of subtle hearing symptoms requires advanced testing methodologies.

    Purpose:

    • To describe a novel audioanalyser system for enhanced hearing assessment.
    • To enable more accurate and differentiated analysis of auditory perception.

    Summary:

    • The audioanalyser employs continuous sweeping frequencies (20 Hz–20,000 Hz) and distinct control signals.
    • It incorporates patient self-testing for monaural/binaural assessments, allowing for fine-tuned frequency testing and comparison.
    • The system facilitates detailed analysis of sound perception, including the role of high-frequency tones and transients in auditory discrimination.

    Impact:

    • Provides unprecedented detail in audiological assessments, revealing new aspects of sound perception.
    • Offers a more accurate method for identifying hearing loss, particularly concerning high tones and transient sounds.
    • Empowers patients in their hearing assessment process, leading to greater awareness of auditory changes.
