What's New
Build history, newest first.
Initial release of the Hearing Aids & Cochlear Implants set: six cited chapters — Hearing Aids (introduction, styles & components, signal processing, prescription & fitting, verification & outcomes) and Beyond Hearing Aids (implantable devices).
Practice surfaces: six worked clinical cases on device choice and fitting, a self-assessment quiz (browse / spaced-repetition / timed), a glossary, references, and a progress dashboard.
Interactive figures from the start: the amplification spectrum, the hearing-aid styles family, an animated signal-chain diagram, an interactive compression input/output curve, an interactive prescription-target chart, a real-ear-measurement chart, and an implantable-device comparison. Animations respect prefers-reduced-motion; the pure math is unit-tested.
