Description: Central auditory processing disorders (CAPD) present diagnostic challenges due to the involvement of complex neural networks responsible for sound localization, auditory discrimination, and temporal processing. This session explores the application of electrophysiological methods—particularly auditory brainstem responses (ABR), middle latency responses (MLR), and cortical auditory evoked potentials (CAEP)—as objective tools to assess central auditory function. Emphasis will be placed on clinical applicability, interpretation strategies, and integration with behavioural test findings.

Outcome Objectives: At the end of this session, participants will be able to:

1. Define the neural mechanisms underlying central auditory processing.
2. Describe key electrophysiological techniques relevant to CAPD assessment.
3. Identify electrophysiological patterns associated with central auditory dysfunction.
4. Integrate objective and behavioural findings for a comprehensive clinical evaluation.

Background: Central auditory processing involves the perceptual processing of auditory information within the central nervous system and the neurobiological activity that underpins this processing. CAPD can affect language development, learning, and everyday communication, particularly in pediatric and geriatric populations. Behavioural tests, while informative, are limited by their reliance on attention, memory, and language skills.

Electrophysiological methods provide a means of assessing auditory system integrity and processing efficiency independent of patient cooperation. Studies have demonstrated the value of CAEPs and MLRs in identifying cortical involvement and temporal abnormalities in CAPD cases. Moreover, the frequency-following response (FFR) has been proposed as a promising tool to evaluate the encoding of complex sounds at the subcortical level.

These objective measures complement behavioural evaluations and can support differential diagnosis, especially in populations with limited behavioural test reliability. As audiology increasingly incorporates neurophysiological tools into routine practice, electrophysiology-based assessments are becoming vital for evidence-based management of CAPD.

Description: This presentation will explore how various types of listening and hearing difficulties impact musical perception, drawing from a wide range of auditory conditions including sensorineural hearing loss, tinnitus, single-sided deafness, and users of hearing aids or cochlear implants. Rather than focusing solely on hearing loss, the session will provide a broader overview of how different hearing profiles affect the perception of musical elements such as pitch, melody, rhythm, and timbre. The presentation will also examine how amplification technologies influence musical experiences, and how music perception differs across populations with varying auditory capacities. Through this multifaceted approach, the talk aims to shed light on the complex interaction between hearing and music, while also highlighting gaps in current clinical practices.

Outcome Objectives:

- To demonstrate how different hearing conditions—ranging from mild hearing loss to profound deafness—affect musical perception.
- To discuss how hearing aids and cochlear implants influence the perception of pitch, melody, and rhythm.
- To raise awareness about the role of music perception as a sensitive indicator of auditory function across clinical populations.
- To encourage audiologists and clinicians to consider music perception in assessment and rehabilitation planning.
- To advocate for the development of music-based tools that can enhance auditory outcomes in individuals with hearing loss and listening difficulty.

Background: Musical perception involves intricate auditory processing skills, including frequency discrimination, temporal sequencing, and sound pattern recognition. These skills can be significantly affected not only by central auditory processing disorders but also by peripheral hearing loss and auditory asymmetries. For instance, individuals with single-sided deafness may experience spatial and harmonic imbalance, while tinnitus sufferers may report disrupted pitch perception. Hearing aids and cochlear implants, though successful in improving speech intelligibility, often provide a limited or distorted musical experience due to constraints in frequency resolution and dynamic range. Understanding the specific challenges faced by each group can help improve device programming, rehabilitation strategies, and patient satisfaction. This presentation will draw on existing research and clinical observations to explore the musical perception challenges and potentials of individuals with diverse hearing backgrounds, aiming to integrate music perception more deeply into audiological care.
