Natural listening environments are filled with competing sounds. One mechanism that helps overcome this challenge is spatial release from masking (SRM), whereby spatial separation between a target signal and interfering sounds improves perception of the target....
No actionable clinical change at this time; findings are foundational neuroscience that may eventually inform early hearing assessment norms, but no clinical protocol is yet indicated.
Understanding the developmental timeline of spatial hearing in infants could inform future benchmarks for auditory processing assessments and the timing of interventions in children with hearing loss.
- 01Infant brains show cortical tracking of speech in competing-sound environments as early as the first year of life.
- 02Spatial release from masking — the benefit of hearing a target voice from a different direction than noise — begins emerging in infancy.
- 03EEG-based cortical tracking measures were used to capture neural responses in pre-verbal infants.
- 04Findings published in Journal of Neuroscience (2026), a high-impact peer-reviewed journal.
- 05Study advances understanding of early auditory development beyond simple detection thresholds.
Infant cortical tracking of speech reveals emerging spatial release from masking within the first year of life.
