Crunch test: could hearing loss steal the joy of a crispy biscuit?
NCT ID NCT04923087
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study investigates whether older adults with age-related hearing loss (presbycusis) can still hear and enjoy the sound of a crunchy biscuit while eating. Researchers will compare a crunchy biscuit with a soft one in 100 seniors aged 65 and older, asking them if they hear the crunch and if it gives them pleasure. The goal is to see if offering crunchy foods could help improve appetite and nutrition in elderly people who often struggle with soft, bland diets.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Crunchy biscuit (Protibis) vs soft biscuit (Nutra Cake)
- What this could lead to
- If seniors with hearing loss can still hear and enjoy crunching, caregivers may offer more textured foods to boost eating pleasure and nutrition.
- What could go wrong
- This is a small, early-stage observational study. Results may not apply to all seniors, and the biscuits themselves are not a treatment for hearing loss or malnutrition.
