For everyone, understanding speech in crowded environments such as busy workplaces or social gatherings requires concentration. New RNID‑funded research from Professor Maria Chait’s lab at University College London is helping to explain the hidden effort involved....
No actionable change yet — the research is at an early, exploratory stage; pupillometry is not ready for routine clinical use, but it may eventually offer objective measures of listening effort beyond standard audiometry.
Objective measurement of listening effort (the mental energy used to follow conversations in noise) could close a significant gap in audiology assessment, where patients report fatigue and difficulty not captured by conventional hearing tests.
- 01UCL's Prof Maria Chait uses pupillometry to measure the cognitive effort (mental strain) of listening in noise.
- 02Pupil dilation is used as an involuntary marker of how hard the brain is working to process speech.
- 03The method targets "hidden" listening effort not detected by standard audiograms or speech tests.
- 04Research is RNID-funded and appears to be in an early, pre-clinical phase.
- 05Could inform future hearing device design and rehabilitation strategies if validated.
Pupillometry can measure the hidden listening effort required to understand speech in noisy environments.
