Hearing aid use significantly improves hearing-specific quality of life in older adults.
Hearing aid intervention leads to sustained improvements in health-related quality of life specifically related to hearing for both new and experienced users.
International Journal of Audiology · 2023
Key Findings
- 01Significant improvements in hearing-dimension scores were observed at two-month follow-up and sustained at long-term follow-up for both first-time and experienced hearing aid users.
- 02Total 15D scores significantly decreased at long-term follow-up for both user groups.
- 03Self-reported hearing abilities, word recognition scores, and hearing aid usage time were positively correlated with increased 15D scores.
Application
Design takeaway
Focus on optimizing the hearing experience and its direct impact on user well-being, acknowledging that assistive devices may not solve all associated quality of life challenges.
How to apply
When designing assistive listening devices, conduct user research to measure not only functional improvements but also the impact on specific quality of life dimensions relevant to the device's purpose.
Project actions
- 01When evaluating a design, consider using validated questionnaires to measure user well-being.
- 02Think about how your design impacts specific aspects of a user's life, not just its primary function.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large sample size.
- +Prospective observational design allows for tracking changes over time.
Limitations
The study's findings might be specific to older adults and the 15D questionnaire; results may differ for other age groups or with different quality of life measures.
Reliability & validity
The study uses a validated questionnaire (15D) and a large sample size, contributing to its reliability. The prospective design enhances validity by observing changes over time.
Think critically
If hearing aids improve hearing quality of life but not overall quality of life, what other factors might be negatively impacting the overall quality of life for these individuals, and how could design address those?
Design Principles
"Assistive technologies should demonstrably improve the primary user experience and its directly related quality of life metrics."
This research highlights the profound impact of assistive technology on user well-being, particularly for sensory impairments. Designers of assistive devices must consider not only the functional performance but also the long-term psychological and social benefits that contribute to an improved overall quality of life.
What This Means for Your Design
Wearing hearing aids makes older people feel better about their hearing, and this feeling lasts a long time, even if their overall health feeling doesn't improve as much.
How to use in your project
- 1.Reference this study to justify the importance of measuring quality of life improvements in your design project, especially if it involves assistive technology or aims to enhance user well-being.

Paragraph starter
This research indicates that assistive technologies, such as hearing aids, can lead to significant and sustained improvements in specific areas of user quality of life (e.g., hearing-related aspects). This underscores the importance of evaluating design solutions not only on their functional performance but also on their impact on user well-being, as measured by relevant quality of life indicators.
