Interventions

  • Soundfield Behavioral Audiometry — OTHER
    Single 15-minute behavioral soundfield hearing detection task comparing conventional warble tones, narrow-band noise, and band-pass filtered familiar music stimuli (BPF-FMS). Group 1 receives BPF-FMS generated via the baseline filtering algorithm; Group 2 receives BPF-FMS generated via the optimized filtering algorithm

Study Details

Hearing tests are crucial for a child's development, but the standard test, Visual Reinforcement Audiometry (VRA), often doesn't work for those with social communication disorders (SCD) and autism spectrum disorder (ASD). A standardised filtering tool has been developed. Understanding how the results from this new music test compare to standard test results, particularly in people with hearing loss, is critical to establishing the fundamental psychoacoustic threshold relationship. This basic science research validates the acoustic methodology before any future clinical diagnostic application can be considered

Enrollment
100 participants (estimated)

Arms

  • Arm: Phase 1 Cohort (Initial Filtering Strategy)
    50 participants (35 recruited at GSTT and 15 at CHEAR Ltd) with confirmed stable permanent bilateral hearing loss, evaluated using the initial baseline band-pass filtered familiar music stimuli (BPF-FMS) strategy (Work-Package 4)
  • Arm: Phase 2 Cohort (Optimized Filtering Strategy)
    50 independent participants (35 recruited at GSTT and 15 at CHEAR Ltd) with confirmed stable permanent bilateral hearing loss, evaluated using the updated/optimized band-pass filtered familiar music stimuli (BPF-FMS) strategy refined following Phase 1 analysis (Work-Package 6

Primary Outcome Measure

Binaural Sound-field Hearing Threshold Concordance (BPF-FMS vs. Warble Tones) [ Time Frame: At time of testing (Single 15-minute appointment session) ]
