Hearing aid

The first mention of a hearing aid was made in 1588 by an Italian Giovanni Porta. In a book entitled Natural Magick, he described wooden aids shaped like animal ears.

Carmelite monk Père Sebastian Jean Truchet invented the ear trumpet in the 17th century. His pioneering model was basically a long horn with a large pointed opening at one end.

Electrical hearing aids were invented in 1901 by Miller Hutchinson. These first hearing aids weighed 16 lbs and had to be placed on the user's lap or on an adjacent table.
