Development of Competency Criteria for Real-Ear Measurement: Findings From a Modified E-Delphi Round 1.

Area of Science:

• Audiology
• Hearing Science
• Medical Device Technology

Background:

• Hearing aid verification is crucial for audibility and speech access.
• Best practices mandate evidence-based measures like on-ear and simulated real-ear aided response (REAR).
• Audiologist competency in REAR measurement and interpretation develops through six skill stages.

Purpose of the Study:

• To achieve consensus on critical competency criteria for audiologists performing hearing aid verification.
• To ensure effective real-ear performance evaluation across the lifespan.
• To define standards for hearing aid fitting and audiological care.

Main Methods:

• A modified e-Delphi technique surveyed 29 expert audiologists.
• 54 competency items were categorized into seven domains.
• A 7-point Likert scale assessed agreement, with 70% consensus required.

Main Results:

• Consensus was reached on 52 of 54 competency items.
• Over 90% agreement was found for competencies in calibration, equipment setup, and REAR interpretation.
• Items lacking consensus were revised for a second survey round.

Conclusions:

• Key competencies for performing on-ear and simulated REAR were identified.
• This forms a basis for audiology training and knowledge development.
• The study aims to enhance clinical practice and improve patient outcomes in hearing aid fitting.
