The middle ear also connects to the upper throat at the nasopharynx via the pharyngeal opening of the Eustachian
Analog ear Master". A number of U.S. (and foreign) patents on topics related to Stewart's analog ear were granted. In the order of filing dates starting in 1962, numbers are 3,294,909, 3,325,597, 3,387,093, 3,432,618, 3,378,700, 3,483,325, 3,459,034, 3,543,138, and 3,510,588. Several groups have built analog VLSI hearing chips in recent decades. Analog ear An analog ear or analog cochlea is a model of the ear or of the cochlea (in the inner ear) based on an electrical, electronic or mechanical analog. An analog ear is commonly described as an interconnection of electrical elements such as resistors, capacitors, and inductors; sometimes transformers and
