Description
Shawn S Goodman leads a team modeling how the inner ear's echo grows with sound level, in a 2026 paper. The echo, a faint tone the ear itself makes, reveals how healthy the cochlea is. Its growth curve shape shifts with the test setup, which clouds what the curve says about hearing.
Their method fits the curves with a hidden growth model borrowed from structural equation work. A smooth S-shaped curve stands in for the ear's hidden nonlinearity, while a linked fit handles noisy readings. Data from twelve young adult ears, plus simulated tests, showed the fit stayed sound when signals were weak. It also recovered standard curve traits like slope and threshold. The team aims the tool at future hearing diagnosis work.
