Real World Assessment of listening challenges and Hearing Aid Benefit through a Client-Oriented Scale of Improvement (COSI) and Ecological Momentary Assessment approach

Key Points

• To evaluate the impact of hearing loss on daily life and the effectiveness of hearing aids using real-world methods.
• Used client-oriented scale of improvement (COSI) to measure perceived benefits of hearing aids.
• Employed ecological momentary assessment to capture listening challenges in daily life situations.
• Analyzed data from real-world environments rather than controlled settings.
• Identified key areas where hearing aids improve user experience in complex scenarios.
• Demonstrated that standard clinical assessments may not reflect real-life listening difficulties.
