From stone age to data-driven tech for ears: a time travel
summary
A concise timeline and practical checklist that moves from shells and horns through vacuum tubes and transistors to digital aids in the 1990s and cochlear implants that stimulate auditory nerves not amplify sound, noting implants often use only half the cochlea so speech sounds high pitched or robotic. Notes Bluetooth adoption around 2012 and machine learning captions around 2019, plus current limits: rechargeable batteries ~16 hours and hearing tech using noise‑filtering neural nets. Concrete tips: show your face, feed audio via Bluetooth or induction loop, use closed captions, keep background music low.
